Mapping Technology Reveals the Brain’s Secret Protein Factories

DNA is just the beginning. A new mapping technology reveals that brain cells produce proteins at wildly different rates, providing a missing link in our understanding of neurological disease.

Moderate Cannabis Use May Protect the Aging Brain

A massive study of over 26,000 middle aged and older adults reveals that those who use cannabis in moderation have larger brain volumes and sharper cognitive skills than non-users.

Memory of Food: Brain Circuits Control Appetite Through Context

Forget the "willpower" myth, new research suggests that your past experiences are the real secret to appetite control. By identifying a hidden circuit that links memory to hunger, scientists have discovered how the brain uses your environment to decide when it's time to eat, and how a "glitch" in this system leads to overeating.

Hippocampus Predicts Rewards by Reorganizing Memories

Researchers have discovered that the hippocampus isn't just for memory; it acts as a predictive model that shifts neural activity to anticipate rewards, providing new insights into Alzheimer’s.

Hidden Brain Layers Revealed in Key Memory Center

Scientists have identified a previously unseen layered organization inside one of the brain’s most important memory hubs. The CA1 region of the hippocampus was found to contain four distinct bands of neuron types, each defined by unique genetic signatures that shift subtly across the structure.

Brain Uses Molecular Timers to Decide What We Remember

New research shows that long-term memory is not stored by a single molecular switch, but by a sequence of timed genetic programs unfolding across different brain regions. Using a virtual-reality learning model in mice, scientists found that experiences are promoted or demoted through multiple biological “durability gates.”

Stress-Like Behaviors Traced to a Single ATP Circuit in the Brain

New research reveals that reduced ATP signaling in the hippocampus plays a causal role in both depression- and anxiety-like behaviors. In stressed male mice, ATP levels and the ATP-releasing protein connexin 43 were markedly lower.

Lifelong Social Bonds Keep the Aging Brain Sharp and Flexible

Rats that lived in social groups throughout their lives retained youthful memory and mental flexibility well into old age, according to new research. Even with equal physical stimulation, only socially connected rats performed as well as younger ones on complex memory tests, while isolated rats showed significant decline.

Do You Get Déjà Vu? Memory Glitches Make Time Feel Repeated

Déjà vu—the eerie feeling that a new moment has happened before—has puzzled scientists and philosophers for centuries. Neuroscientists now believe it’s a normal brain glitch tied to how memory and perception interact.

How the Brain Extinguishes Fear Memories

Scientists have, for the first time, identified the brain signals linked to extinguishing fear memories in humans. Using implanted electrodes and advanced Representational Similarity Analysis, they showed that theta activity in the amygdala increases when previously unpleasant cues are re-learned as safe.

Gene Blueprint of Neural Stem Cells in the Brain Identified

A new study has mapped the genetic blueprint of neural stem and progenitor cells (NPCs), the rare cells responsible for generating new neurons in the adult brain. Using a digital sorting algorithm and cross-species analysis, researchers identified 129 NPC-specific genes, 25 of which are already linked to neurological disorders and 15 that may explain previously unknown conditions.

Blocking Protein Reverses Age-Related Memory Loss

Aging disrupts memory by increasing levels of the protein FTL1 in the hippocampus, new research shows. In mice, excess FTL1 caused neurons to grow abnormally and led to memory decline, while reducing FTL1 reversed these impairments.
