Structural vascular alterations have been proposed as contributors to schizophrenia, yet direct anatomical evidence remains limited. Using unbiased stereological methods, this study examined whether microvessel architecture is altered in key subcortical regions of the human brain. ... Read More

Presenilin-1 familial Alzheimer’s disease mutations cause progressive microvascular degeneration in the hippocampus. These vascular defects arise independently of amyloid plaque deposition. ... Read More

Prolonged social isolation selectively impairs hippocampus-dependent contextual fear memory. This effect is associated with CA1 shrinkage and reduced synaptic PSA-NCAM expression. ... Read More

Floor plate–derived human dopamine neurons show robust survival and functional integration after transplantation. This approach advances stem cell–based therapy for Parkinson’s disease. ... Read More

Hippocampal neuron loss occurs in APP/PS-1 transgenic mice independent of local amyloid plaque burden. These findings indicate that non–plaque-related mechanisms contribute to neurodegeneration in Alzheimer’s disease. ... Read More

Aging leads to significant loss of both principal neurons and inhibitory interneurons in the dorsal prefrontal cortex. In contrast, ventral prefrontal regions remain structurally preserved.... Read More
