Machine learning spots neural progenitors in adult human brains
But the finding has not settled the long-standing debate over the existence and extent of neurogenesis during adulthood, says Yale University neuroscientist Juan Arellano.

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.

Expanded view of hippocampal function comes into focus
After decades of debate, the region’s role is being rewritten. Rather than using sensory input to simply log key points in time and space, the hippocampus may serve to contextualize our experiences and memories—and ultimately make predictions about the future.

Gazing at a location from afar activates place cells in chickadees
The results help explain how the hippocampus can recall information about a place without an animal physically revisiting it.

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.

Sleep doesn’t just consolidate memories; it actively shapes them
The rapid eye movement (REM) phase preserves newly acquired memories, but deeper non-REM sleep helps to adapt and update them, according to “heroic” day-long electrode recordings in rats.

What infant fMRI is revealing about the developing mind
Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.

Molecular changes after MECP2 loss may drive Rett syndrome traits
Knocking out the gene in adult mice triggered up- and down-regulated expression of myriad genes weeks before there were changes in neuronal function.

Single-neuron recordings are helping to unravel complexities of human cognition
As this work begins to bear fruit, researchers “are becoming less afraid to ask very difficult questions that you can uniquely ask in people.”

Timing tweak turns trashed fMRI scans into treasure
Leveraging start-up “dummy scans,” which are typically discarded in imaging analyses, can shorten an experiment’s length and make data collection more efficient, a new study reveals.

Perimenopause: An important—and understudied—transition for the brain
Many well-known perimenopause symptoms arise in the brain, but we still know little about the specific mechanisms at play. More research—in both animals and humans—is essential.
