Why Alzheimer’s Patients Forget Loved Ones

Researchers have discovered that the heartbreaking moment when a person with Alzheimer’s no longer recognizes family may stem from the breakdown of perineuronal nets, protective structures that support social memory. In mice, the loss of these nets erased memory of familiar individuals while sparing object memory, mirroring early human symptoms.

Newly Mapped Brain Circuit Reveals How Memories Stay Stable During Learning

A new study reveals how brain circuits between the entorhinal cortex and hippocampus stabilize memories during learning. Researchers found that synchronized signals between excitatory and inhibitory neurons in these regions help strengthen “place maps,” ensuring memories remain consistent even as new information is learned.

Epigenetic Switch to Turn Memories On and Off Created

Researchers have shown for the first time that flipping an epigenetic “switch” in specific memory-holding neurons can directly alter memory strength. By targeting the gene Arc—which helps neurons adjust their connections—scientists used CRISPR-based tools to either boost or silence its activity in engram cells within the hippocampus.

Daily Light and Sound Therapy May Slow Alzheimer’s Decline

A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset Alzheimer’s disease. After two years of treatment, participants maintained stronger cognitive performance than typical Alzheimer’s patients and showed reduced levels of tau protein, a key disease biomarker.

Psychedelics May Rewire Memory Circuits Key to Mental Health

New research suggests that psychedelic drugs may work by strengthening specific brain connections linked to memory and cognition. Scientists found that under psychedelic exposure, neurons in the claustrum—a region dense with psychedelic-sensitive receptors—intensified their communication with the anterior cingulate cortex, a region involved in mood and psychiatric disorders.

Gene Editing Reverses Age-Related Memory Loss

Researchers have identified molecular mechanisms behind age-related memory decline — and shown they can be reversed. Two studies revealed that correcting specific molecular processes in the hippocampus and amygdala, and reactivating a silenced memory-supporting gene called IGF2, improved memory in older rats.

What Makes Certain Memories Impossible to Forget?

Scientists are asking the public to share their most vivid memories to uncover why some moments feel as fresh as the day they happened. The project blends cognitive neuroscience with literature, examining how vivid memories are experienced, evolve with age, and even differ across centuries.

How the Brain Learns New Facts About Imaginary Worlds

Learning new information about the world—like details from a fantasy realm—engages brain regions distinct from those used to recall personal experiences. In a new study, participants learned fictional facts about imaginary civilizations and were later tested on what they remembered.

How Storytelling Style Shapes the Way the Brain Forms Memories

The way an event is described—through feelings or sensory detail—changes how the brain stores and recalls it. In this study, participants listened to stories that emphasized either conceptual details (thoughts and emotions) or perceptual details (sights and sounds).

Theta Brain Waves Act Like Radar to Boost Visual Working Memory

New research shows that the brain’s ability to detect subtle visual changes—like spotting an anomaly on a security monitor—depends on theta-frequency brain waves (3–6 Hz) that rhythmically sweep across the cortex. These traveling waves act like a radar, scanning different parts of the visual field and influencing when and where attention peaks.

Why Teenage Songs Define Us: The Science of Musical Memory

A global study reveals that our most emotionally resonant music tends to come from our teenage years—typically peaking around age 17. This “reminiscence bump” marks the period when our developing brains most strongly imprint musical memories that help form identity.

Astrocytes, Not Neurons, Hold the Key to Emotional Memory

New research reveals that astrocytes — not neurons — are responsible for stabilizing emotional memories by re-engaging during recall. After an emotionally intense event, such as fear, specific astrocytes become biologically tagged with adrenoreceptors, making them responsive when the memory is later reactivated.
