Why Some 80-Year-Olds Have the Memory of 50-Year-Olds

For 25 years, scientists have studied “SuperAgers”—people aged 80 and above whose memory rivals those decades younger. Research reveals that their brains either resist Alzheimer’s-related plaques and tangles or remain resilient despite having them.

This shows a brain with the amygdala and hippocampus glowing red.

How the Brain Reactivates Emotional Experiences

A new study using direct recordings from human brains reveals how the amygdala and hippocampus coordinate to form and retrieve emotional memories. During aversive memory encoding, high-frequency gamma activity in the amygdala shapes hippocampal responses, which are later reactivated in the hippocampus—but not the amygdala—during memory recall.

Brain Decodes Visual Memories by Timing, Not Just Firing Neurons

A new study has uncovered how the brain efficiently encodes and recalls visual memories—by organizing them into categories and using the precise timing of neuronal activity.

Your Brain Maps the Same Path Differently Every Time

New research shows that our brain’s internal map rewrites itself every time we navigate a familiar environment. Even when mice experienced identical virtual mazes with controlled sensory input, their hippocampal neurons activated in different patterns on each run.

Hunger Sharpens Sleep Rhythms That Solidify Memories

New research shows that the brain’s slow oscillations and sleep spindles — key rhythms that consolidate memories during sleep — can be shaped by more than just age. While these rhythms have long been thought of as stable traits, studies reveal that metabolic state, like fasting before sleep, can enhance their timing and co-occurrence.

Right-Sided Brain Pathway Linked to Social Dominance

A new study uncovers how brain anatomy relates to social dominance in primates. Researchers found that the uncinate fasciculus, a tract tied to emotion and memory, strongly correlated with dominance behaviors in squirrel monkeys. This link was especially pronounced in the right hemisphere, aligning with human findings on social aggression.

The Brain’s Ripple Effect: How Memories Are Structured

Researchers have identified ripple-type brain waves as key to how humans segment and store memories. By recording brain activity in epilepsy patients watching a TV episode, they found ripples marked event boundaries in the hippocampus while supporting information processing in cortical areas.

How the Brain Selects Between Perception and Memory

The brain constantly toggles between focusing on external sensory information and internal mental representations like memories, plans, and thoughts. This seamless switching is crucial for adaptive behavior, yet the underlying mechanisms remain poorly understood.

Tiny Brain Region Orchestrates How We Segment and Remember Life Events

Our memories don’t flow like a continuous stream—they’re divided into meaningful events, thanks to a tiny brain region called the locus coeruleus. New research shows this region acts like a “reset button,” activating at event boundaries to signal the hippocampus to store distinct memories.

Hippocampus and Insula Team Up to Encode Emotional Memories

A new study explored how the hippocampus and insula interact during the encoding of emotional memories in humans. Sixteen participants with implanted electrodes viewed emotionally valenced words and attempted to recall them while neural activity was recorded.

Protein Found to Strengthen Brain Cell Connections for Memory

Scientists have identified how the brain protein cypin helps maintain strong connections between neurons, a discovery with implications for treating brain injuries and neurodegenerative diseases. Cypin ensures proper protein tagging at synapses, allowing neurons to communicate effectively and support memory and learning.

Memory Chooses Meaning Over Surface Similarities

Memory helps us make sense of the present by retrieving past experiences based on either surface-level similarities or deeper conceptual connections. A new study reveals that when a familiar mental category — like excuses or conflicts — is available, memory prioritizes structural, abstract links over superficial cues.
