Generation of human nucleus basalis organoids with functional nbM-cortical cholinergic projections in transplanted assembloids

3 weeks 4 days ago
The nucleus basalis of Meynert (nbM), the major cholinergic output of the basal forebrain, regulates cortical modulation, learning, and memory. Dysfunction of the nbM-cortical cholinergic pathway is implicated in neurodegenerative and neurodevelopmental disorders, including Alzheimer's disease (AD) and Down syndrome (DS). Here, we generated human nbM organoids (hnbMOs) from human pluripotent stem cells (hPSCs) containing functional cholinergic projection neurons. Then we reconstructed...

The Genetic Architecture of the Human Corpus Callosum and its Subregions

3 weeks 4 days ago
The corpus callosum (CC) is the largest set of white matter fibers connecting the two hemispheres of the brain. In humans, it is essential for coordinating sensorimotor responses and performing associative or executive functions. Identifying which genetic variants underpin CC morphometry can provide molecular insights into the CC's role in mediating cognitive processes. We developed and used an artificial intelligence based tool to extract the midsagittal CC's total and regional area and...
