Activation was higher for actual movement than for imagined movement. Across the postoperative period, movement-related activation decreased in magnitude, relative to an imagined-movement baseline. Movement-related activation also became more focused, postoperatively, on hand-related brain regions, in contralateral sensorimotor cortex. Some movement-related brain activation was relatively stronger for the right hand, postoperatively, consistent with the fact that the patient had been right-handed, preoperatively. To our knowledge, this is the first hand-transplant recipient to exhibit more pronounced brain activation, post-transplantation, for actual movement relative to imagined movement.

In this study, 92 patients were examined to determine which impairments continue to affect multiplication performance even in the chronic phase after a first-time unilateral left-hemispheric stroke. Our results revealed a strong association between impaired multiplication performance and the disconnection of left long-term memory (para)hippocampal areas from left frontal and right parietal regions. Thus, unlike previous findings in the acute stroke phase, our results in the chronic phase emphasize the importance of (para)hippocampal regions for successful multiplication performance. We suggest that the affected areas and connections in chronic patients with persistent multiplication problems not only indicate areas that are crucial for the relearning of arithmetic facts, but also those crucial for the learning of arithmetic facts in general. More generally, we suggest that the acquisition of arithmetic facts depends on structural integrity of a network centered around the left (para)hippocampus, while the retrieval of consolidated arithmetic facts from memory relies on the integrity of a left-hemispheric network involving angular gyrus and middle temporal gyrus.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"192 ","pages":"Pages 78-89"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional research has focused on the role of alpha oscillations as an endogenous pacemaker for the human internal clock, yet there is limited evidence supporting this idea. An alternative hypothesis proposes that alpha oscillations may underlie a sampling mechanism, where higher alpha frequencies correspond to increased information sampling, resulting in more accurate temporal judgments. In this study, we tested the internal clock versus sampling rate hypothesis by examining the relationship between Individual Alpha Frequency (IAF) and fine-grained time perception. Using resting Electroencephalography (EEG) and Signal Detection Theory (SDT), fifty healthy volunteers performed a time-discrimination task with 100 and 500 msec standard durations. Our results demonstrate that temporal sensitivity (d’) but not temporal bias (c) is influenced by IAF, with higher IAF leading to more accurate time estimates (higher d’). The correlations were observed over frontocentral topographies consistent with previous reports of neural networks involved in time processing and were most pronounced at 100 msec relative to 500 msec, likely due to fluctuations in IAF across multiple cycles. In conclusion, our findings support the relationship between IAF and temporal sensitivity. These results challenge the pacemaker hypothesis and instead suggest a distributed mechanism where alpha oscillations enhance the precision of temporal sampling. Our study adds to the growing body of evidence highlighting the role of IAF in sensory sampling as a generative mechanism for temporal sensitivity as opposed to subjective time perception.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"192 ","pages":"Pages 183-195"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145257519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the specificity of prediction for other musical features has not been fully addressed. The present study investigated whether predicted instruments are decoded from the EEG signal during omission to examine the specificity of prediction in the timbre dimension. Thirty-five participants listened to unfamiliar melodies with simple (high predictability) or complex (low predictability) timbre change rules while watching a silent movie. The EEG was recorded when a tone expected to be played by one of four specific timbres (celesta, electric piano, marimba, organ) was omitted. The results showed that the amplitude of an omitted stimulus potential, oN1, did not differ between high and low predictability conditions. However, the support vector machine was able to decode the type of musical timbre during omission better than random chance in the high predictability condition but not in the low predictability condition. These results suggest that EEG signals contain information about which instrument should be played during omission, but this information is not manifested in traditional event-related potentials.

However, the brain signal variability underlying self-processing remains scarcely treated in the literature. Additionally, less is known about whether the processing of self-referential visual content can be modulated by facial expressions of emotion, as these resemble more natural situations than neutral expressions. This study therefore investigated the brain signal variability underlying self-referential visual processing and its possible interaction with emotional facial expressions, as indexed by multiscale entropy analysis (MSE). This metric captures the temporal complexity or variability contained in neural patterns at varying timescales. Thirty-two participants were presented with distinctive facial identities (self, friend, and unknown) displaying different facial expressions (happy, neutral, and angry) and performed an identity recognition task. Our results showed that brain signal variability decreases in response to self-faces compared to other identities. Similarly, brain signal variability also decreases for friend faces relative to unknown faces. This reduction in complexity could be indicative of greater efficiency during the preferential processing of personally relevant stimuli. Furthermore, the data observed here show that self-processing is unaffected by facial expressions of emotion, suggesting an independent processing of identity from more dynamic facial information, particularly when the task demands are focused on identity recognition. These results provide novel evidence of the moment-to-moment brain signal variability involved in the identity of the self and others. The evidence presented here adds to a growing literature highlighting the relevance of neural variability for understanding brain-behavior relationships.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"192 ","pages":"Pages 1-17"},"PeriodicalIF":3.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed a significant decrease in left-hand temperature in the incongruent condition, compared to an increase in the congruent condition. SCR amplitude correlated with temperature: cooling was associated with reduced SCRs, while warming predicted stronger responses.
