Brain’s Working Memory Limits Tied to Learning, Not Just Capacity

A new study reveals that working memory limitations stem from learning challenges rather than storage capacity. Using a computer model of the basal ganglia and thalamus, researchers showed that holding too much information at once confuses the brain, impairing its ability to learn and use stored data effectively.

FDA Approves Adaptive DBS for Parkinson’s Patients

The FDA has approved adaptive deep brain stimulation (aDBS), a breakthrough therapy that adjusts in real time to Parkinson’s disease symptoms. Unlike traditional DBS, which delivers constant stimulation, aDBS monitors brain activity and responds with precise electric pulses to prevent stiffness and involuntary movements.

Adverse Childhood Experiences Impact Brain Development and Mental Health

A decade-long study reveals how childhood adversity alters brain development, increasing risks for mental health disorders and substance use. Researchers found that teens who experienced early adversity showed delayed cognitive control, with unusual brain activity in regions linked to self-regulation.

This shows a man, immune cells and a bed.

Poor Sleep Alters Immune Cells, Increasing Risk for Inflammatory Diseases

A new study reveals that even a single night of sleep deprivation can alter immune cell profiles to resemble those seen in obesity, a condition linked to chronic inflammation. Researchers found that sleep-deprived individuals had increased levels of non-classical monocytes, immune cells associated with inflammatory responses, similar to patterns observed in obese participants.

AI Model Predicts Brain Aging Speed to Detect Cognitive Decline Early

A new AI model can measure how fast a person’s brain is aging using MRI scans, providing a powerful tool for detecting cognitive decline. Unlike previous methods, this model tracks brain aging over time, identifying regions most affected and correlating changes with cognitive function.

Low-Normal B12 Levels Linked to Slower Brain Processing

Even when within the normal range, lower levels of vitamin B12 may contribute to cognitive decline, according to a new study. Researchers found that older adults with lower biologically active B12 had slower cognitive processing and more white matter lesions, despite meeting current nutritional requirements.

Genetic Mutation Linked to Schizophrenia Alters Brain Function

Researchers identified a rare genetic mutation in two schizophrenia patients that increased schizophrenia-related behaviors in mice. The mutation led to higher levels of glycine decarboxylase (GLDC), an enzyme that degrades glycine, reducing NMDA receptor activation.

Repurposed Blood Pressure Drug May Treat ADHD

A new study suggests that amlodipine, a widely used blood pressure medication, could help manage ADHD symptoms. Researchers tested five potential drugs in rats bred for ADHD-like behaviors, and only amlodipine significantly reduced hyperactivity.

Optimism and Pessimism Shape Resilience and Risk

Researchers examined how optimism and pessimism influenced well-being and behavior during the COVID-19 pandemic. Analyzing data from a large-scale study of older adults, they found that optimism was linked to lower stress and greater resilience, while lower pessimism was associated with safer health behaviors.

Every Breath You Take Alters Your Visual Perception

Researchers have discovered that breathing affects pupil size, with the pupil being smallest during inhalation and largest during exhalation. This newly identified mechanism is independent of external stimuli and could influence vision by alternating between detail enhancement and object detection.

How the Brain Ignores Distractions to Stay Focused

When focusing in noisy environments, the brain adjusts not by concentrating harder but by ignoring distractions that were previously disruptive. Researchers developed a neural network model showing that people fine-tune their attention based on past experiences with distractions.

Brain’s Hidden Circuitry for Risk and Reward Uncovered

Researchers have identified two distinct groups of neurons that help the brain evaluate risk and reward in decision-making. These neurons, located in the ventral striatum, separately process better-than-expected and worse-than-expected outcomes.
