Emotion research has a communication conundrum
In 2025, the words we use to describe emotions matter, but their definitions are controversial. Here, I unpack the different positions in this space and the rationales behind them—and I invite 13 experts to chime in.

Memory study sparks debate over statistical methods
Critics of a 2024 Nature paper suggest the authors failed to address the risk of false-positive findings. The authors argue more rigorous methods can result in missed leads.

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.

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.
