Article Abstract
Patients with neurodegenerative diseases exhibit diminished basal forebrain (BF) volume compared to healthy individuals. However, it's uncertain whether this difference is consistent between sexes. It has been reported that BF volume moderately atrophies during aging, but the effect of sex on BF volume changes during the normal aging process remains unclear. In the cross-sectional study, we observed a significant reduction in BF volume in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) compared to Healthy Controls (HCs), especially in the Ch4 subregion. Notably, significant differences in BF volume between MCI and HCs were observed solely in the female group. Additionally, we identified asymmetrical atrophy in the left and right Ch4 subregions in female patients with AD. In the longitudinal analysis, we found that aging seemed to have a minimal impact on BF volume in males. Our study highlights the importance of considering sex as a research variable in brain science.

Both the medial prefrontal cortex (mPFC) and thalamus have been implicated in pain regulation. However, the roles of the mPFC-thalamus connection in pain and how the mPFC modulates nociceptive processing within the brain remain unclear. Here, we show that the mPFC neurons that project to thalamus are marked by expression and deactivated in both acute and chronic pain.

Aim: The bed nucleus of the stria terminalis (BST), situated deep within the basal forebrain, serves as a key relay in circuits regulating emotion, stress, and autonomic responses. Despite its clinical relevance, particularly in anxiety-related disorders, its detailed white matter connectivity remains underexplored. This study aims to provide an in-depth anatomical description of the BST and its structural affiliations, with an emphasis on its surgical and neuromodulatory relevance.

Down syndrome (DS), stemming from the triplication of human chromosome 21, results in intellectual disability, with early mid-life onset of Alzheimer's disease (AD) pathology. Early interventions to reduce cognitive impairments and neuropathology are lacking. One modality, maternal choline supplementation (MCS), has shown beneficial effects on behavior and gene expression in neurodevelopmental and neurodegenerative disorders, including trisomic mice.

The nucleus accumbens (NAcc) and ventral pallidum (VP) are key nodes in the mesolimbic reward pathway that facilitate stimulus salience, including the regulation of social motivation and attachment. Primate species display variation in social behaviors, including different levels of impulsivity, bonding, and aggression. Previous research has implicated neuromodulation of the reward pathway in the differential expression of various social behaviors, suggesting that differences in neurotransmitter innervation may play a role in species-specific patterns.

The basal forebrain (BF) acts as a pivotal relay station in the transmission of arousal signals, projecting to both cortical and subcortical structures. Among its downstream targets is the lateral habenula (LHb), which recent research has implicated in the modulation of sleep rhythms and in mediating the loss of consciousness associated with anesthetic agents. In our study, we utilized optogenetic manipulation to selectively modulate the BF neuron projection pathway to the LHb, thereby examining its impact on behavioral and electroencephalographic responses to isoflurane anesthesia.
