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.”

Targeting NMDA receptor subunit reverses fragile X traits in mice
The subunit acts as a “volume control” on signaling that shapes the density of dendritic spines, the new work suggests.

Coding bonus: Bats’ hippocampal cells log spatial, social cues
The neurons represent not only an animal’s place in space, but also the distinguishing features of its fellow bats, including their sex and social status.

Remembering Eleanor Maguire, ‘trailblazer’ of human memory
Maguire, mastermind of the famous London taxi-driver study, broadened the field and championed the importance of spatial representations in memory.

More than two dozen papers by neural tube researcher come under scrutiny
One of the studies, published in 2021 in Science Advances, received an editorial expression of concern on 21 May, after the journal learned that an institutional review of alleged image problems is underway.
