Common shrews exhibit large, reversible seasonal shifts in brain and regional volumes, driven by neuronal shrinkage and dendritic retraction rather than altered cell counts. The hypothalamus, thalamus and select cortical and striatal regions show the strongest changes, consistent with energetic adaptation to winter conditions.... Read More

Parafascicular neurons express high levels of Cbln1 and innervate medium spiny neurons, and Cbln1 deletion increases MSN spine density while leaving dendritic architecture unchanged. These findings indicate a regulatory role for Cbln1 in limiting excitatory thalamostriatal input.... Read More

Early life stress suppressed LBP expression in the developing hippocampus and led to increased spine density, abnormal spine structure and impaired cognition in adulthood. LBP knockout mice showed similar synaptic and behavioral abnormalities, indicating LBP’s role in microglia-mediated synaptic refinement.... Read More

Diagnostic-level ultrasound modestly increases basal dendritic branching and activates mechanosensitive signaling pathways in developing cortical neurons, with repeated exposure amplifying markers of neuronal activation.... Read More

Neocortical pyramidal neurons can form autapses, self-synaptic loops onto their own basal dendrites that may provide a localized feedback mechanism for modulating excitatory drive.... Read More

A computerized light-microscopy system that recorded 3D coordinates and performed real-time geometric calculations enabled fast, accurate measurement of Golgi-stained neurons. The platform cut analysis time from ~24 hours to ~45 minutes and produced reproducible micron-scale measurements.... Read More
