Prozac May Rewire the Brain by Loosening Rigid Neural Circuits

A new study shows that fluoxetine, better known as Prozac, does more than increase serotonin—it changes how brain cells handle energy and rebuild connections. After two weeks of treatment, parvalbumin interneurons in the prefrontal cortex became less rigid, with mitochondrial energy genes reduced and plasticity genes upregulated.

Nanoplastics Disrupt Brain Energy, Threatening Memory Function

Scientists have uncovered a mechanism by which nanoplastics impair brain energy metabolism, offering new clues into environmental contributions to neurodegeneration. The particles disrupted mitochondrial electron transfer and reduced energy production in both general and synaptic mitochondria.

Shrews Shrink and Regrow Brains, Offering Clues for Human Diseases

Scientists used non-invasive MRI to study shrews that seasonally shrink and regrow their brains, uncovering water loss as the key driver of this rare phenomenon. Despite losing about nine percent of their brain volume in winter, shrew brain cells remain alive, with aquaporin-4 proteins playing a key role in regulating water movement.

Brain Rewiring Patterns May Predict Alzheimer’s Years in Advance

Researchers have discovered that people with Alzheimer’s show unusually high neural flexibility—the constant reorganizing of brain networks—even while resting. In a large study of older adults, higher neural flexibility in the visual network predicted which healthy participants would later develop dementia.

Brain Retains Lost Limb’s Control Map, Defying Plasticity Theories

A groundbreaking study challenges decades of neuroscience by showing that the brain retains its map of a lost limb long after amputation. Using functional MRI scans taken before and after surgery, researchers found little change in cortical activity, even when participants attempted to move phantom fingers.

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.

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.

Light Exercise Boosts Memory via Dopamine and Noradrenaline

New research reveals that even light exercise, like jogging or yoga, activates key neurotransmitter systems that enhance memory by stimulating the hippocampus. In a rat model mimicking human exercise, scientists found that dopamine and noradrenaline levels increased in the hippocampus during low-intensity activity.

How Memories Take Shape at the Synapse Level

A groundbreaking new technique called EPSILON allows researchers to map the proteins involved in memory formation with unprecedented detail, providing a window into the molecular architecture of learning. This approach focuses on tracking AMPARs—key receptors that regulate synaptic strength—over time, illuminating how the brain encodes, strengthens, and stores memories.

Oxygen Boost Sparks Early Brain Growth

A new study reveals that raising oxygen tension during weeks four to six of brain organoid development significantly promotes neurogenesis, guided by the oxygen-binding protein neuroglobin. Using cerebral organoids and cutting-edge imaging, researchers monitored internal oxygen levels and linked their changes to key stages in early brain development.

Psilocybin Shows Promise for Parkinson’s Mood and Motor Symptoms

A new pilot study reveals that psilocybin—the compound found in psychedelic mushrooms—may significantly improve mood, cognition, and motor function in people with Parkinson’s disease. The compound was well tolerated, with only mild side effects, and benefits persisted for weeks after dosing. While the study was primarily designed to test safety, researchers observed meaningful and lasting improvements in multiple symptoms.
