How the Brain Uses Place Cells to Anchor Episodic Memories

Researchers have developed a model explaining how place cells in the hippocampus anchor both spatial and episodic memories. Grid cells in the entorhinal cortex interact with hippocampal cells to create a scaffold, linking memories to specific neural patterns.

Why PTSD Develops in Some but Not Others

Fear memories initially form broad associations, but over time, they shift to become episodic memories tied to specific timelines. This process involves the hippocampus early on, with the dorsolateral prefrontal cortex integrating the event sequence later.

How Your Brain Remembers: How Episodic Memories Form

Researchers developed a computer model that mimics how the hippocampus stores new episodic memories without erasing old ones. This model demonstrates that the CA3 region of the hippocampus serves as an anchor point for memories, allowing efficient storage in surrounding regions.

Bird Brains: Jays Show Episodic-like Memory

A new study finds that Eurasian jays exhibit episodic-like memory, a type of memory previously thought to be unique to humans. The birds were able to remember incidental details of past events, such as the visual characteristics of cups used in a food-hiding experiment.

Memory Mechanics: How Young Brains Transition from Gist to Episodic Memory

Researchers discovered key molecular mechanisms that shift children's memory formation from general or "gist-like" to event-based or "episodic". This change in memory formation typically occurs between ages four and six. The study identified that the maturation of inhibitory cells called parvalbumin-expressing (PV) interneurons, wrapped by a dense matrix called the perineuronal net, enables memory specificity and appropriately sized engrams.

Stimulation of the Cerebellum Improves Episodic Memory in Older People

Transcranial direct current stimulation (tDCS) of the right cerebellum improved episodic memory in elderly people, a new study reports. The findings open the door to developing new, non-invasive therapies to treat age-related memory and cognitive problems.

Magnetic Stimulation of the Brain Can Improve Episodic Memory

Repetitive transcranial magnetic stimulation (rTMS) applied to the left prefrontal cortex can improve episodic memory performance by reducing the power of low frequency of brain waves during memory formation.
