In healthy aging, prior knowledge becomes increasingly important to guide visual exploration during episodic encoding and retrieval and can hinder performance when incongruous with to-be-learned information. It remains unclear, however, how the dynamic integration of visual information and prior knowledge is altered in neurodegenerative disorders, and whether this impacts oculomotor behaviour. Here, we explored how degradation of the conceptual knowledge base in semantic dementia (SD) impacts the acquisition and retrieval of new information, and how such changes relate to oculomotor behaviour. Ten well-characterised cases of SD were compared to 12 disease-matched cases of Alzheimer's disease (AD) and 24 healthy older Controls. Participants completed a visual search task followed by a surprise memory task where target objects were displayed in either semantically congruent or semantically incongruent locations. Oculomotor performance was evaluated by measuring the time participants spent exploring target congruent areas in each condition. Relative to Controls, visual search and memory performance was significantly compromised in AD, as indexed by slower response times, reduced task accuracy, and more extensive visual exploration directed towards target congruent areas. In contrast, SD patients scored in line with Controls for all behavioural and oculomotor measures on the visual search task when target objects were displayed in semantically incongruent locations. Overall, our findings suggest that degradation of the semantic and episodic memory systems in dementia differentially impacts visual exploration and memory retrieval depending on stimulus congruency.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"218 ","pages":"Article 109250"},"PeriodicalIF":2.0,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144841302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated whether and how the non-human primate brain encodes the naturalistic dynamics (plausibility) of biological and non-biological motion in temporal and spatial domains by presenting monkeys with video clips of biological and non-biological motion under three conditions: (1) normal (forward and upright), (2) temporally reversed, and (3) spatially inverted. Whole-brain analyses revealed that the superior temporal sulcus (STS) preferentially responded to forward, upright biological motion, reflecting sensitivity to naturalistic dynamics (plausibility) in both temporal and spatial domains. Within the STS, a consistent posterior-to-anterior gradient was observed in both monkeys: temporal plausibility was encoded posteriorly, spatial plausibility anteriorly, and both in the intermediate region. These results suggest that the primate STS is selectively tuned to the naturalistic dynamics of biological motion, with its posterior subregion contributing to the evaluation of temporal plausibility, which may underlie time-direction judgments in specific perceptual contexts.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"218 ","pages":"Article 109247"},"PeriodicalIF":2.0,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144859398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research suggests that sleep, particularly rapid eye movement (REM) sleep, may have a role in processing the emotional load of past events.

Some studies have reported increased emotionality in dreams as the night progresses, possibly reflecting ongoing emotional processing in the sleeping brain. However, findings on how dream affect evolves throughout the night remain mixed. In this study, we investigated how emotional intensity in conscious experiences during sleep changes across the night and sleep stages. Participants (N<sub>subjects</sub> = 20) were subjected to a multiple awakening paradigm, where they were awakened 4–5 times throughout the night and asked to recall their dreams (N<sub>dreams</sub> = 61). Additionally, they rated the emotional intensity of their experiences using a structured cued questionnaire. Emotional intensity in dreams increased significantly throughout the night, with late-night dreams being more emotional than dreams collected during earlier sleep. Contrary to our expectation, this increase was not driven by dream reports obtained from REM sleep awakenings. Moreover, late-night dream reports were also significantly longer than those from early sleep, yet the length of the dream reports did not correlate with their emotional intensity. This suggests that the emotionality of dreams is not directly linked to the ability to recall the dream or its narrative complexity. Instead, it could be driven by emotional processes occurring independently throughout the night, or by other factors that regulate our access to dream experiences and their emotional content.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"218 ","pages":"Article 109248"},"PeriodicalIF":2.0,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144841303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the chosen hand, motor evoked potential (MEP) amplitudes started increasing 156 ms before the reaction time, with no differences across stimulus and response interference conditions. In the unchosen hand, MEP amplitudes did not differ significantly from baseline throughout response preparation.

The phenomenon, termed action-induced suppression, highlights the predictive processes in sensorimotor integration but remains controversial regarding the underlying mechanisms. The predictive coding framework posits that action-induced suppression is a general, non-action-specific process driven by predictions. In contrast, the Dual-Stream Prediction Model (DSPM) argues that motor-based and memory-based predictions are mediated by distinct processes — motor predictions rely on precise action-perception mappings and temporal synchrony, whereas memory predictions are based on learned associations. To test these competing theories, we compared auditory ERP responses elicited by self-initiated keypresses (motor-based) and visually cued auditory events (memory-based) in a matching judgment task. Results revealed significant suppression at the P2 component, when the prediction matched the auditory feedback only in the motor-auditory task but not in the visual-auditory task. The findings qualitatively replicated common observations of action-induced suppression; the suppression effects are at a later component rather than N1, indicating the interaction between prediction and perception at a higher level, such as syllable categorization in the current experimental design. Surprisingly, we observed N1 enhancement to the auditory probe in both conditions, with greater enhancement in the motor-auditory task compared to the visual-auditory task. The enhancement effects likely reflect a prediction-induced attentional-like modulation at an early auditory processing stage, potentially driven by the demands of the matching judgment task. Together, these findings support the DSPM by demonstrating functional dissociable mechanisms of motor-based and memory-based predictions.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"218 ","pages":"Article 109242"},"PeriodicalIF":2.0,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144772985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We highlight key challenges in this endeavour, arising from the structural and functional properties of LPFC, including large spatiotemporal receptive fields, dynamic tuning, and integrative connectivity. To address these challenges, we introduce topographic similarity analysis (TSA), an approach inspired by representational similarity analysis (RSA). We discuss the potential of TSA for detecting reorganization of functional topographies with learning and changing task demands, with empirical work applying TSA to macaque cell recordings underway. This work motivates further exploration of topographies across a richer task space.
