Unexpected words that become your best memories: How sentential constraint and word expectedness affect memory retrieval
Höltje G, Bader R, Meßmer JA, Zogaj D and Mecklinger A
Much is known about how the strength of contextual support from strongly constraining (SC) and weakly constraining (WC) sentences influences the online processing of expected (EXP) and unexpected (UNEXP) sentence-ending words. In the present study, we investigated the long-term mnemonic consequences associated with the processing of contextually constraint words and used event-related potentials (ERPs) to explore the memory retrieval mechanisms at work. Furthermore, we investigated false memories for expected but unpresented words. If these unpresented words remained highly accessible in memory, their false recognition as familiar would manifest in a larger early frontal old/new effect, the putative ERP correlate of episodic familiarity. Behavioral results indicated that strongly expected and highly unexpected words were more likely to be recognized, whereas memory for moderately expected words was attenuated. However, the anticipated early frontal old/new effects in these conditions did not materialize. Instead, the retrieval of highly unexpected (SC-UNEXP) words was characterized by a late parietal old/new effect, reflecting a reliance on recollection-based processes. Unexpectedly, during retrieval SC-UNEXP words also evoked a late frontal positivity, a pattern usually associated with the inhibition of unpresented expected words during encoding. This suggests that the retrieval of these words reactivated inhibitory mechanisms akin to those activated during encoding. Additionally, expected lures that were correctly identified as new elicited a broadly distributed positive slow wave, indicative of recollective processing in support of a recall-to-reject strategy. This latter effect was observed irrespective of the predictive strength of the contextual support.

Precision neurodiversity: personalized brain network architecture as a window into cognitive variability
Mohammad SI, Azzam ER, Vasudevan A, Ismail SM, Ayaz H and Prasad KDV
Precision neurodiversity marks a shift in neuroscience from pathological models to personalized frameworks that view neurological differences as adaptive variations. This review synthesizes current knowledge on the Personalized Brain Network architecture and its relationship with cognitive variability in both typical and neurodiverse populations. The study examines advancements in connectome-based prediction modeling, normative modeling, dynamic fingerprinting, and machine learning methods that characterize individual-specific neural networks. Recent findings indicate that the Personalized Brain Network profile reliably predicts cognitive, behavioral, and sensory phenomena. Additionally, deep generative models demonstrate high fidelity in synthesizing connective cells. Recent studies have identified distinct neurobiological subgroups in conditions such as attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder that were previously undetectable by conventional diagnostic criteria. However, research has revealed significant network-level differences among these subgroups. Researchers have identified age-resistant biomarkers in specific brain regions, and genetic mutations significantly influence the connectivity patterns of individuals. Clinical applications span a range of neurodevelopmental conditions, including autism, ADHD, dyslexia, and talent. Network variability predicts executive functioning, social perception, and sensory processing abilities. However, successful translation requires overcoming challenges related to statistical power, reproducibility, ethical implementation and community participation. The convergence of advanced neuroimaging, artificial intelligence, and personalized medicine offers unprecedented opportunities for tailored interventions, while celebrating neurological diversity as a source of human strength.
Targeting the parietal memory network with tDCS in MCI: study protocol for a randomized controlled trial
Cankaya S, Akturk A, Karakus A, Hanoğlu L, Mardinoglu A and Yulug B
Mild cognitive impairment (MCI) is a critical transitional stage in dementia related disorders. In that context, dorsolateral prefrontal cortex (DLPFC), and lateral parietal cortex (LPC) are subjected to neuropathological changes in MCI. Furthermore, alterations in parietal memory network (PMN) integrity and default mode network (DMN) also occur in MCI. Transcranial direct current stimulation (tDCS) is a promising neuroprotective tool that might interfere with cognitive decline in Alzheimer's disease-MCI (aMCI) and Parkinson's disease-MCI (PD-MCI) when applied to DLPFC or LPC separately.

At the same time, technological innovation is driving a shift toward AI-powered diagnostics, immersive learning tools, and neurostimulation-based interventions.
Aesthetics, illusion of success and age interactions: disentangling effects in the closed-loop design with sham neurofeedback training
Naas A, Rohrbach S, Shabestari PS, Neff P and Sonderegger A
This study examined the influence of the aesthetics of visual feedback stimuli in neurofeedback training (NFB). Previous research shows a lack of specific design standards in NFB research and its application. Beyond limited literature on continuous and intermittent feedback presentation effects, most NFB design parameters remain largely understudied. Studies in the context of interface design has pointed at possible effects of aesthetics and task difficulty, indicating an interaction effect of aesthetics on performance and perseverance in difficult task conditions. The study at hand evaluates whether similar effects emerge in the context of NFB. In order to address this question, aesthetics and NFB illusion of success were manipulated experimentally in a sham NFB study ( = 24) following a 2 × 2 within-subjects design. The main dependent variables were perseverance behavior, subjective workload, motivation, and EEG activity. Results indicated an interaction between pleasing design, illusion of success, and participant age affecting perseverance and physical demand. Alpha-1 band amplitudes were modulated by an interaction between pleasing design and age, and a main effect of the illusion of success emerged. Surprisingly, only the illusion of success variable appeared to exert a meaningful influence on the workload and motivation context. Discussing the observed results, the study partially confirms the hypothesis of aesthetics affecting the outcome when the task is difficult in the context of NFB. The relevance of the age variable is addressed, and potential effects in the context of executive functioning and technology adoption processes are considered. Results encourage further research on the topic of NFB design optimization, including verum NFB in the patient population to increase NFB therapy potential.
Human neural correlates of emotional well-being (EWB): a preliminary systematic review and meta-analysis of MRI studies based on a recent consensus definition
Luo J, Lay CM, Richter CG, Turnbull A, Richlan F, Park CL and Hoeft F
Emotional well-being (EWB) is a multifaceted construct essential for human health, conceptualized as an umbrella term for related psychometric concepts such as psychological well-being (PWB), positive mental health, health-related quality of life, thriving, and subjective well-being (SWB). However, varying definitions have prompted calls for a consensus definition. Understanding the neural mechanisms of EWB is crucial for health and intervention efforts, yet findings remain inconsistent in both empirical studies and systematic reviews. The inconsistencies in prior systematic reviews may arise from diverse definitions, an emphasis on task-independent over task-dependent modalities, and biases introduced when statistical analyses are lacking.
Supporting autistic adults with complex communication needs in making their voices heard: examining an adaptation of the framework
Beauchamp MLH, Scorah J and Elsabbagh M
Autistic adults with speech, language and/or cognitive challenges are often excluded from research, particularly from studies examining first-person perspectives, as these generally require that participants have strong speech, language, and cognitive skills. The current pilot study extends previous work and examines whether the framework can be adapted for use with a pre-existing interview the - version (CANDID-R).

The effects of aquatic and land-based interventions on children with developmental coordination disorder
Ferreira LF, de Souza CJF, de Oliveira JA and Freudenheim AM
Knowledge about the effects of aquatic intervention on children with developmental coordination disorder (DCD), as well as the maintenance of these effects over time, is still scarce. We believe that there is a need to advance our knowledge of this subject, for which we have set ourselves the following objectives: (1) to test whether the effects of aquatic and land-based interventions influence the motor performance of children with DCD; (2) to check whether these effects persist over time; and (3) whether the effects of aquatic and land-based interventions bring motor performance values closer together between children with DCD and those with typical development.

Cocco ES, Thouant CL, Pietrosanti L, Infarinato F, Manzia CM, Romano P, Torcisi RSM, Franceschini M, Verrelli CM and Pournajaf S
Parkinson's disease (PD) is the second most common neurodegenerative disease in the world and involves impairment of both motor and cognitive functions, significantly affecting the quality of walking and consequently the quality of life of people affected by this disease. This study analyzed the relationship between gait alterations and cognitive deterioration, using validated clinical tests and an innovative indicator, the -bonacci gait number, which quantifies gait harmonicity, symmetry, and consistency. Kinematic data collected during the 6-Minute Walk test on 19 people with PD (pwPD) and 15 healthy adults were analyzed. The results highlighted a significant negative correlation between gait harmonicity and cognitive performance (-bonacci gait number-Time Up and Go Dual Task;  = 0.797,  < 0.05). Finally, mediation analysis showed that global cognitive function (MoCA) indirectly influences gait harmonicity through TUG-DT. The results suggest that gait in pwPD is strongly modulated by executive-attentional functions, supporting its cognitive modulation rather than a purely automatic nature. This study allowed to explore the complex relationship between cognitive functions and the motor system, deepening how these interactions influence and refine motor behavior. Therefore, rehabilitation programs combining motor exercises and cognitive training could be more effective in improving gait quality, reducing the risk of falls, and improving person's quality of life.

The effects of weight-bearing manipulations on gait and its underlying neural control mechanisms in toe walking children
Gwerder M, Visscher RMS, Spescha A, Hosseini Nasab SH, Kim YK, Zibold R, Brunner R, Taylor WR, Viehweger E and Singh NB
In toe walking children, impaired maturation of neuromotor control often leads to persistent use of immature motor programs. Understanding the underlying etiology of toe walking in children with cerebral palsy (CP) and idiopathic toe walking (ITW) is crucial for advancing rehabilitation strategies. This study examined gait adaptations and H-reflex responses to varied weight-bearing conditions to determine whether children with ITW and CP exhibit distinct neuromotor control strategies compared to typically developing (TD) peers.

Golińska-Drobienko PB, Sawicki A, Bieleninik Ł, Schinwelski M and Bidzan M
Cognitive impairment is a prevalent nonmotor symptom of Parkinson's disease (PD), significantly affecting patients' quality of life. Considering the gap in understanding the relationship between cognitive impairments in Parkinson's disease and executive function, this study aimed to investigate the association between three cognitive statutes: normal cognition condition (PD-NCC), mild cognitive impairment (PD-MCI), and mild dementia (PDD), and the performance of the Anterior Attentional System in individuals with Parkinson's disease.
The cost of language: functionally over-dominant language circuits in the human brain may limit cognitive abilities and non-verbal executive functions
Lipp HP
Evolutionarily, the most recent connective system in the human brain is the language circuitry. However, its presence may impose restrictions on higher executive functions apparent as non-verbal talents in art, science, and management- essentially a conflict between talking and doing. Since the associative cortex underlies thinking, the question then is how much of it is assigned to language functions, and how much is left for associative networks that support non-verbal functions such as planning and parallel processing. Arguments: (i) The determinant of neocortical network organization is the motor cortex, which acts as the main attractor for all processes in the hemispheres yet is split in two sub-attractors formed by disproportionally enlarged zones of origins for two bundles, the corticospinal tract co-driving movements of arms and hands, and the corticobulbar tract to the motor nuclei of the cranial nerves innervating the vocal tract, tongue and face. (ii) This arrangement must entail different functional properties of the associated networks. The language network faces executive limits because the linear generation of words becomes dominated by cerebellar feedback from lingual processing ("one word generates the next"), while the non-verbal networks have more freedom in generating mental goals and movements. (iii) Functional imbalance between these neocortical networks results from altered connections caused by neuronal competition during brain development, either by epigenetic events or by selectable genetic factors. (iv) The descent of the larynx in humans during the paleolithic period and the following self-domestication and neoteny during the last 30,000 years have favored the expansion of the cerebral language network. Voices gained prosody and melody, thereby transmitting fine-grained levels of emotions between individuals, facilitating the evolution of collective cooperation in agricultural economies. On the other hand, with the advent of densely populated kingdom states, emotional voicing also enabled mass control of people for warfare and social stratification of societies. This new environment entailed genetic adaptation of a large population segment resulting in moderately lowered cognition, firstly by expansion of the language network permitting emotional association of simple memes and words, possibly supported by additional mechanisms conserving a child-like stage of brain development responsible for word-linked beliefs.
Neurobehavioral concomitants of alcohol use in older healthy adults
Nixon SJ, Torres SA, Boissoneault J, Garcia CC and Lewis B
Few laboratory studies permitting granular analyses of alcohol use on neurobehavioral processes in older adults have been reported. This study, reporting baseline data from an on-going longitudinal project, seeks to address this gap. Toward that end, working memory (WM) processes were targeted using the continuous recognition version of the Mnemonic Similarity Task (MST). Healthy male and female drinkers aged 65-80 years completed self-report measures of substance use, negative affect and demographics prior to testing. Drinking patterns were quantified on the basis of typical standard drinks/day (D/D). Behavioral data were obtained in a two-button forced choice paradigm. Neurophysiological data were obtained for each stimulus presentation with analyses focusing on a mid-frontal negative shift occurring ∼ 300-500 ms post stimulus (FN400) and a posterior positive shift occurring ∼ 550-800 ms after stimulus presentation (LPC). To constrain the models, for the behavioral analyses correlations between D/D, measures of negative affect, stimulus condition ("new," "identical," or "similar") and performance were conducted. They indicated that only accuracy in labeling "new" items was related to D/D. Subsequent least squares regression revealed that D/D was inversely related to accuracy for new items. In a sensitivity analysis removing THC users, the D/D effect was retained. Correlations incorporating mean amplitudes for the FN400 and LPC failed to reveal identifiable patterns. Consequently, separate mixed models (e.g., stimulus condition) for FN400 and LPC were conducted. D/D was not predictive of the FN400 for any stimulus condition. It was negatively related to the LPC mean amplitude. In analyses, the effect was most notable for "new" stimuli. After removing THC users, the magnitude and direction of the D/D effect was retained, although the p value fell short of significance. Primary models failed to reveal sex main or interaction effects. However, exploratory analyses justify their continued study. These data lend preliminary support for the hypothesis that sustained drinking among older adults may negatively impact neurobehavioral processes. They are also consistent with expectations that alcohol effects may be modest and constrained by specific process. Importantly, these outcomes will be expanded through on-going longitudinal study, extending investigation to study of alcohol-related cognitive decline.
