Bilingual Brains Build Stronger Connections Learning a second language, especially in childhood, can boost brain connectivity and support lifelong cognitive flexibility. New research shows bilingual brains have more efficient networks, benefiting attention and brain health.

A simple smell test could detect early cognitive decline, offering a new way to identify Alzheimer’s risk before memory loss begins. The nose might be brain health's new frontier. https://lnkd.in/e__fjJdB

A new study highlights that olfactory testing could offer a simple, cost-effective way to detect early cognitive impairment from home. Researchers found that older adults with mild cognitive issues performed worse on odor identification and memory tasks than cognitively normal individuals. https://lnkd.in/gynsxkUc

Psychedelics May Enhance Intimacy, Attraction, and Sexual Expression Psychedelics may do more than heal the mind—they might deepen intimacy, shift sexual expression, and enhance relationships, according to a new study of nearly 600 users. https://lnkd.in/gynsxkUc

How Sleep, Emotion, and Novelty Shape Memory Smartphones are transforming memory science. New studies show that sleep, novelty, and emotion captured via apps like HippoCamera can strengthen real-world memories—offering new tools to enhance memory in daily life. https://lnkd.in/gZ6iGuu7

Infomorphic Neurons Bring AI One Step Closer to Brain-Like Learning Researchers have developed a new kind of artificial neuron—called infomorphic neurons—that can independently learn and self-organize with nearby neurons, mimicking the decentralized learning of biological brains. Inspired by pyramidal cells in the cerebral cortex, these neurons process local signals to adapt and specialize in tasks without external control. https://lnkd.in/dPw2Bzde

Fear of Emotions Fuels PTSD-Related Conflict in Romantic Relationships People with PTSD symptoms often fear their emotions, which fuels destructive communication patterns with partners. New research shows this emotional fear may be key to breaking the cycle of PTSD and relationship distress. https://lnkd.in/gdS2u4hv

Less Deep Sleep Linked to Brain Shrinkage, Alzheimer’s Risk Less REM and deep sleep may mean smaller brain volume in Alzheimer’s-vulnerable areas, new research shows. Improving sleep could be key to protecting brain health and reducing dementia risk. https://lnkd.in/gUXG2Ux6

Genes Play a Role in Why We Love Music A new genetic study reveals that our capacity to enjoy music is partly inherited, with 54% of music enjoyment variability linked to DNA differences. Researchers analyzed data from over 9,000 twins to explore whether genetics influence how much pleasure people derive from music. https://lnkd.in/g5dZCmVB

Glutamate Unlocks Brain Cell Channels to Enable Thinking and Learning Researchers used advanced cryo-electron microscopy to capture atomic-level images of how glutamate, a key neurotransmitter, opens channels in brain cells. These channels, known as AMPA receptors, are essential for neuron-to-neuron communication and play a role in learning, memory, and disorders like epilepsy. https://lnkd.in/g9AfPDfC
