Spatial learning circuitry fluctuates in step with estrous cycle in mice
Cyclic shifts in estradiol levels coincide with changes in dendritic spine density and the activity of place cells in the CA1 region of the hippocampus, a new study shows.

The big idea with Diego Bohórquez
His theories around the neuropod have challenged the boundaries of classic ideas regarding gut-brain communication.
Learning in living mice defies classic synaptic plasticity rule
Donald Hebb’s theory—memorably summarized as “cells that fire together, wire together”—does not explain the shifting hippocampal connections in mice learning to navigate a virtual environment, according to a new study.

Exclusive: Layoffs revoked at U.S. National Institute of Neurological Disorders and Stroke
After more than a month of uncertainty, 30 previously purged employees at the institute no longer face termination.
‘Ancient’ brainstem structure evolved beyond basic motor control

Hessameddin Akhlaghpour outlines how RNA may implement universal computation
Could the brain’s computational abilities extend beyond neural networks to molecular mechanisms? Akhlaghpour describes how natural universal computation may have evolved via RNA mechanisms.

Immune cell interlopers breach—and repair—brain barrier in mice
The choroid plexus, the protective network of blood vessels and epithelial cells that line the brain’s ventricles, recruits neutrophils and macrophages during inflammation, a new study shows.
