Neurons receive thousands of signals via tree-like extensions called dendrites. Until now, these dendrites were thought to be relatively smooth cables that conduct electrical signals to the cell body.

New research from Carnegie Mellon University reveals that dendritic spines—the tiny structures that help brain cells communicate and form memories—don't fit neatly into a few categories. Instead, they ...

Structural plasticity of dendritic spines is a fundamental mechanism of learning and memory. It depends on the release of brain-derived neurotrophic factor (BDNF) and activation of its receptor, ...

If you've ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close ...

Fragile X syndrome (FXS) is the most common inherited form of intellectual disability and a leading monogenic cause of autism, yet effective treatments remain elusive. Previous work showed that ...

Synaptic plasticity in the hippocampus involves both strengthening relevant connections and weakening irrelevant ones. That sapping of synaptic links, called long-term depression (LTD), can occur ...

In a recent study published in Science Advances, a group of researchers assessed whether dendritic spine head diameter in the temporal cortex is a better predictor of episodic memory performance in ...

Over the course of life, memory fades with varying degrees, robbing older people of the ability to recollect personal experiences. This progressive, nearly inevitable process has long been ...
