How developing neurons simplify their search for a synaptic mate Jun 06, 2025

Show notes

Streamlining the problem from 3D to 1D eases the expedition-a strategy the study investigators deployed to rewire an olfactory circuit in flies.

'Understudied secret' in brain dampens nicotine drive in mice Jun 04, 2025

Show notes

The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Rethinking how neural activity sculpts critical periods Jun 03, 2025

Show notes

New findings on the role of neural activity in developing circuits are challenging our prior notions about the rules that govern critical periods.

To understand the brain as a network organ, we must image cortical layers Jun 02, 2025

Show notes

Human neuroscience research has largely overlooked this spatial scale-which bridges cells and brain areas. But new advances in functional MRI technology are changing that.

Amina Abubakar translates autism research and care for Kenya May 29, 2025

Show notes

First an educator and now an internationally recognized researcher, the Kenyan psychologist is changing autism science and services in sub-Saharan Africa.

Learning in living mice defies classic synaptic plasticity rule May 28, 2025

Show notes

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.

Cephalopods, vision's next frontier May 27, 2025

Show notes

For decades, scientists have been teased by the strange but inaccessible cephalopod visual system. Now, thanks to a technological breakthrough from a lab in Oregon, data are finally coming straight from the octopus brain.

Escaping groupthink: What animals' behavioral quirks reveal about the brain May 23, 2025

Show notes

Neuroscientists have long ignored the variability in animals' behavioral responses in favor of studying differences across groups. But work on the brain differences that underlie that variability is beginning to pay off.

Immune cells block pain in female mice only May 22, 2025

Show notes

Regulatory T cells in the spinal meninges release endogenous opioids in a sex-specific manner, new work shows.

The BabyLM Challenge: In search of more efficient learning algorithms, researchers look to infants May 19, 2025

Show notes

A competition that trains language models on relatively small datasets of words, closer in size to what a child hears up to age 13, seeks solutions to some of the major challenges of today's large language models.
