Despite comprehensive information about the posterior limb, there is limited and conflicting information about the anterior limb in the literature. We aimed to show the anatomical relationships of the AC with neighboring structures by using white matter microdissection and magnetic resonance (MR) tractography, primarily on the anterior limb of the AC. Twenty cadaveric human brains and three sheep brains were prepared according to Klingler's method. White matter fiber microdissections were performed. MR tractography was done in 20 specimens. This study defined the body and anterior and posterior limbs of the AC. The anterior limb leaves the body from the inferior side at the level of the anterior perforated substance and olfactory tract. It then courses anteroinferolaterally, curves towards the orbital gyri, and terminates at the olfactory trigone. The posterior limb of the AC divides into rostral (anterolateral) and caudal (posterolateral) parts. The anterior limb was more prominent in sheep than in human brains. This study accurately delineates the anatomy and variations of the anterior limb of the AC in human and sheep brains for the first time in the literature to the best of our knowledge. The anterior limb of the AC is larger in sheep than in humans. An increased importance of olfaction could be the evolutionary explanation for this difference. The MR tractography results shown are unique for this delicate anatomy.</p>","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 8","pages":"143"},"PeriodicalIF":2.9,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Animal models of aging have shown that these behavioral impairments are associated with neuroarchitecture modifications in the prefrontal cortex (PFC) and hippocampus; however, most studies have focused on rats or lack multiple key ages. In this study, we evaluated spatial and recognition memory in male mice at critical ages [3 months (M), 6, 12 and 18] using the Morris water maze (MWM) and novel object recognition test (NORT), respectively. Moreover, we quantified dendritic arborization, spine density and the type of spines in the PFC, CA1 hippocampus and nucleus Accumbens Core (NAcC). Locomotion, assessed in the first phase of NORT, revealed age-dependent reductions. Notably, the 18 M group revealed significant recognition memory deficits. Spatial memory impairments were especially evident at the 12 M group in the MWM. Spine density was increased at 6 M in the NAcC, whereas a reduction was noted at 12 M and 18 M in the PFC. Morphological assessment of spines indicated age-dependent changes, including a notable increase in the proportion of thin spines in the CA1 and PFC regions. However, dendritic arborization remained largely unchanged across the examined brain regions and age groups. Overall, our findings observed age-dependent alterations in memory and morphological alterations in spines in mice, emerging as possible contributors to cognitive decline.

Studies of the Lateral Geniculate Nucleus (LGN) often use proton density (PD) scan protocols, repeated up to 40 times, then manually segment the LGN structure from the average image. Efficiency is crucial when conducting MRI scans: minimising time spent on structural scanning can increase time available for complementary functional MRI scans and/or reduce scanning costs. In this study we asked how segmentation accuracy depended on the number of PD repeats. Four raters segmented the LGN of five participants, using different numbers of PD scans in the average image (1, 2, 4, 8, 16, 24, 32, 40), and an additional experienced expert rater segmented the LGN for just the 40PD average for all participants. We compared how the rater LGN masks at each scan average level overlapped with the expert masks. One rater performed the segmentation for the 40PD average on four separate days, to measure intra-rater variability across repeats. We also used a state-of-the-art automated segmentation process to compare the reliability to manual segmentation. We found that the average overlap between rater masks and the expert masks increased up to the 16PD scan average level, after which there was no additional benefit to including more PD scans. The automated segmentation masks were comparable to the overlap between the raters (40PD) and expert masks.</p>","PeriodicalId":9145,"journal":{"name":"Brain Structure & Function","volume":"230 7","pages":"140"},"PeriodicalIF":2.9,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144942966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst previous studies have mapped intracranial EEG (icEEG) from non-epileptogenic brain regions, they often neglect age and sex effects. Further, they are limited by small sample sizes due to the modality's invasive nature. This study substantially expands the subject pool compared to existing literature, to create a multi-centre, normative map of brain activity which considers the effects of age, sex and recording hospital. Using interictal icEEG recordings from [Formula: see text] subjects across 15 centres, we constructed a normative map of non-pathological brain activity by regressing age and sex on relative band power in five frequency bands. A linear mixed model was implemented to account for the hospital effect. Variable importance was assessed using standard statistical measures, and regression coefficients (and their standard errors) were analysed at both whole-brain and regional scales. Recording hospital significantly impacted normative icEEG maps in all frequency bands, and age was a more influential predictor of band power than sex. The age effect varied by frequency band, but no spatial patterns were observed at the region-specific level. Certainty about regression coefficients was also frequency band specific and moderately impacted by sample size. The concept of a normative map is well-established in neuroscience research and particularly relevant to the icEEG modality, which does not allow healthy control baselines.

NCS projections overlapped partially but uniquely targeted the orbitofrontal and insular cortices. Dopaminergic pathways exhibited connectivity with the striatum, thalamus, and prefrontal cortex, while noradrenergic LC projections displayed lateralized connectivity to occipital, temporal, and frontal regions.
