The desynchronization of this rhythm from baseline to the processing of visual stimuli is used as an index to better understand the development of visual attention. However, development trajectories of desynchronization remain underexplored. Additionally, it is unclear whether development of desynchronization is sensitive to task demands or if it reflects broader developmental changes. To investigate these questions, EEG data were collected from infants aged 6, 9, and 12 months while they passively viewed a fixation cross followed by 10-s trials of a female face or novel object tracked down the screen. Dominant rhythm desynchronization was calculated by subtracting power during the fixation period from power during each task condition. The results revealed significant desynchronization in response to faces at occipital electrodes for all age groups. The magnitude of the desynchronization also increased from 6 to 9 to 12 months of age in response to faces over right occipital electrodes. No significant desynchronization was observed for object stimuli. These findings suggest that dominant rhythm desynchronization develops across infancy and is sensitive to stimulus type. The increased desynchronization for faces compared to objects highlights infants' general preference for faces relative to objects.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the key anatomical pathways through which the cingulate cortex influences behavior is its efferent connection to the locus coeruleus (LC). This brainstem region is responsible for noradrenaline (NA) release and is critical for various cognitive and behavioral functions. However, the specific impact of cingulate subregions on the LC-NA system remains unexplored. This study investigated how the different cingulate cortex areas affect LC-NA activity by measuring pupil-evoked responses (PERs) as an index of LC-NA activity. Using intra-cortical stimulation across the eight cingulate areas in rats, we found that anterior cingulate cortex and midcingulate cortex subregions evoked rare autonomic responses but significant pupil dilations whose amplitude increased along the caudo-rostral and dorso-ventral axes. By using the DSP-4, a neurotoxin-selective ablation of the LC-NA system, we suppressed PER and confirmed the role of LC-NA activity in this response. The differential influence of cortical areas on the PER demonstrates that each subregion of the rat cingulate cortex has the potential to differentially activate the LC-NA system, suggesting a clear parcellation of the rodent cingulate cortex, likely corresponding to functional specialization.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143968924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown that structural changes occur in the brain due to late-onset blindness, including cortical thinning in visual cortical regions.

We evaluated the cortical thicknesses of 10 Argus II participants, 10 blind participants, and 13 sighted participants. The Argus II patients on average had a thicker left cuneus cortex and lateral occipital cortex relative to the blind patients. The duration of the Argus II use significantly partially correlated with thicker visual cortical regions in the left hemisphere. Furthermore, in the 2 case studies (scanned before and after implantation), the patient with longer device use (44.5 months) had an increase in the cortical thickness of visual regions, whereas the shorter-using patient did not (6.5 months). Overall, the Argus II participants' cortical thickness was on average significantly rejuvenated in 2 higher visual regions, and participants using the implant for a longer duration had thicker visual regions.

A total of 123 college student dyads completed a creative ideation task and a contrast task while their brain activity was simultaneously recorded using functional near-infrared spectroscopy. Results identified three distinct ideation pathways-flexibility, persistence, and convergence-that collectively drove group creativity, accompanied by three interbrain synchrony states. STATE2, characterized by enhanced prefrontal-temporal interbrain synchrony, positively predicted group creative performance, whereas STATE3, marked by reduced frontal-parietal interbrain synchrony, negatively predicted it. Specifically, STATE2 facilitated group creativity through three mediating pathways: (1) the flexibility pathway alone, (2) combined flexibility-persistence or flexibility-convergence pathways, and (3) a sequential flexibility-persistence-convergence pathway with chain mediation effects. These findings provide neurobehavioral evidence for the triple-pathway model, underscoring the pivotal role of prefrontal-temporal interbrain synchrony in group creativity. They further demonstrate the dynamic, multi-pathway nature of group creative ideation, showing that a single cohort can flexibly employ three interchangeable pathways to generate novel ideas collaboratively.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144156001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe the major effective connectivity between the hippocampal memory system and the anterior temporal lobe (ATL) semantic memory system in humans. Then, we present and model a theory of how semantic representations may be formed in the human ATL using slow associative learning in semantic attractor networks that receive inputs from the hippocampal episodic memory system. The hypothesis is that if one category of semantic representations is being processed for several seconds, then a slow short-term memory trace associative biologically plausible learning rule will enable all the components during that time to be associated together in a semantic attractor network. This benefits from the binding of components provided by the hippocampal episodic memory system. The theory is modeled in a four-layer network for view-invariant visual object recognition, followed by a semantic attractor network layer that utilizes a temporal trace associative learning rule to form semantic categories based on the inputs that occur close together in time, using inputs from the hippocampal system or from the world.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143981586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the neural level, event boundaries have been shown to align with boundaries between neural states-stable patterns of brain activity maintained over time. These neural states provide a valuable window into the neural underpinnings of event perception. To investigate how neural state boundaries relate to memory across the lifespan, we used the data-driven Greedy State Boundary Search method to implicitly identify neural state changes in younger and older adults' electroencephalography data during movie watching. Memory for the movie was tested and related to (1) neural state correspondence across individuals and (2) the degree to which the pattern of activity changes at boundaries. Neural state boundaries significantly aligned across people, but did not differ with age nor relate to memory. The degree of change at neural state boundaries also did not differ with age, but was positively related to memory for the movie. These findings suggest that age differences in the perception of naturalistic events may be less pronounced than previously thought, at least when measured implicitly, and that greater distinction between successive neural states relates to better memory for one's experiences regardless of age.","PeriodicalId":9715,"journal":{"name":"Cerebral cortex","volume":"35 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12086427/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144092880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
