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.

Inhibitory cells work in concert to orchestrate neuronal activity in mouse brain
A cubic millimeter of brain tissue, meticulously sectioned, stained and scrutinized over the past seven years, reveals in stunning detail the role of inhibitory interneurons in brain structure and function.

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.

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.

Cracking the code of the extracellular matrix
Despite evidence for a role in plasticity and other crucial functions, many neuroscientists still view these proteins as “brain goop.” The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.

Synaptic changes shape winning mice into bullies
When a mouse repeatedly defeats its opponents, brain circuits that underlie aggressive behaviors develop more stable connections, helping to ensure continual triumph, a new study shows.

What makes memories last—dynamic ensembles or static synapses?
Teasing out how different subfields conceptualize central terms might help move this long-standing debate forward. I asked eight scientists to weigh in.

This paper changed my life: ‘Response of hippocampal synapses to natural stimulation patterns,’ by Dobrunz and Stevens
The work demonstrated how to effectively combine controlled in-vitro experiments and the messiness of natural brain patterns.

‘Star’ neuroscientist faked data in paper and grant applications, U.S. government finds
The faked data, which was part of research on the genetic mechanisms of synaptic plasticity, was used to obtain more than $1.4 million in federal funding.

Neurons making memories shush their neighbors
When neurons strengthen their synapses, they “infect” surrounding cells with a virus-like protein to weaken those cells’ excitatory connections, according to a new preprint.

Everything everywhere all at once: Decision-making signals engage entire brain
The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.

Astrocyte networks span large swaths of brain
The networks are plastic, connect brain regions that aren’t connected by neurons and may enable long-distance communication between astrocytes, a new preprint shows.
