“Meal Memory” Neurons Found to Curb Overeating

Researchers have identified neurons in the hippocampus that store "meal memories," encoding both what and when food was consumed. These specialized memory traces, or meal engrams, form during pauses between bites, helping the brain log eating experiences.

Brain Uses Separate Synapses to Balance Learning and Stability

New research has overturned a long-held belief in neuroscience by showing that the brain uses separate synaptic transmission sites for spontaneous and evoked signaling. Traditionally thought to share the same origin, these two forms of communication actually emerge from distinct sites, each following its own developmental path.

This shows AI representations of neurons.

Inhibitory Neurons May Hold the Key to Spatial Learning and Memory

A new study explores how the brain quickly learns and remembers important locations by focusing not on excitatory neurons, but on inhibitory ones called parvalbumin interneurons (PVs). These PVs act like circuit breakers, briefly reducing their activity to allow learning-related neurons to strengthen connections. Using optogenetics and virtual reality mazes in mice, researchers found that learning was blocked when PV inhibition didn’t decrease at the right time.

Night Owls Face Faster Cognitive Decline

People who naturally stay up late, so-called "night owls", are more likely to experience faster cognitive decline than those who are early risers, according to a long-term study. Researchers found that unhealthy behaviors common in the evening, such as poor sleep, smoking, and drinking, may explain part of this risk.

Astrocytes May Hold the Key to Brain’s Vast Memory Capacity

New research proposes that astrocytes—long thought to be merely supportive cells—may significantly enhance the brain’s ability to store memories. Unlike neurons, astrocytes cannot fire electrical signals but can influence synaptic activity through calcium signaling and gliotransmitters.

The Nature of Nostalgia: How Time Transforms Emotion in Memory

New research reveals that nostalgic memories don’t remain emotionally static, they evolve over time. While these memories are typically rich in positive feelings at the time they occur, those feelings tend to fade, making space for rising negative emotions like regret and loneliness.

How the Brain Stores and Edits Memories

A new scientific review maps the cellular and molecular mechanisms behind memory formation, consolidation, generalization, and updating—revealing how memories are stored, altered, and even manipulated in the brain. Key breakthroughs now allow scientists to visualize and activate specific neurons involved in memory, offering deeper insight into how learning occurs and how fear memories may become overgeneralized in disorders like PTSD.

New Alzheimer’s Drug Boosts Brain Protection, Restores Memory

Researchers have identified a promising drug candidate, DDL-357, that improves memory in Alzheimer’s mouse models by increasing levels of a protective brain protein called clusterin (CLU). CLU helps prevent the buildup of toxic amyloid-beta plaques and tau proteins, both key drivers of Alzheimer’s disease.

Color Knowledge Tied to Language-Visual Brain Circuitry

A new study shows that our ability to recall details about familiar objects—like a banana’s typical color—depends on strong connections between visual and language-processing areas of the brain. Researchers found that stroke patients with disrupted neural pathways between these regions had weaker object-color knowledge and altered brain activity.

When Sight Meets Sound: How the Brain Binds Audiovisual Memories

Our brains don’t just remember what we see and hear, they fuse the two into cohesive memories. A new study reveals that when visual and auditory speech cues are synchronized, they trigger rhythmic brain activity that strengthens memory formation.

This shows a brain made of computer chips.

Rewiring Memory: A New Model That Learns Like a Human Brain

A new memory model called Input-Driven Plasticity (IDP) offers a more human-like explanation for how external stimuli help us retrieve memories, building on the foundations of the classic Hopfield network. Unlike traditional models, which assume memory recall happens from a fixed starting point, the IDP framework describes how stimuli reshape the brain’s “energy landscape” in real time to guide memory retrieval.
