Genes Behind Dyslexia Linked to Brain Changes in Motor, Vision, …
Dec 18, 2024 · Summary: A large-scale study revealed that genetic variants linked to dyslexia are associated with differences in brain areas controlling motor coordination, vision, and language. Using data from over a million individuals, researchers calculated genetic “polygenic scores” for dyslexia and analyzed their relationship to brain structures.
How Childhood Trauma Alters Brain Pathways - Neuroscience News
Feb 5, 2024 · Summary: Researchers shed light on the profound effects of childhood trauma on brain development, uncovering significant disruptions in neural networks critical for self-awareness and problem-solving. By leveraging AI to analyze brain scans, the research highlights how early abuse rewires pathways associated with emotions, empathy, and bodily understanding, potentially leading to difficulties ...
How Our Brains Process Music - Neuroscience News
Feb 20, 2024 · Summary: Researchers unlocked how the brain processes melodies, creating a detailed map of auditory cortex activity.Their study reveals that the brain engages in dual tasks when hearing music: tracking pitch with neurons used for speech and predicting future notes with music-specific neurons.
Cells Beyond the Brain Show Surprising Memory Abilities
Nov 9, 2024 · Summary: New research reveals that cells outside the brain can store and process memories, challenging the view that memory is limited to neurons.Scientists found that non-brain cells, when exposed to spaced chemical signals, activated a “memory gene” similarly to neurons. This discovery suggests that learning from repetition could be a fundamental property of all cells.
Reality or Illusion? The Human Battle with Distinguishing …
Apr 21, 2023 · The more vividly we imagine something, the more likely we are to believe it's real, a new study reports. Researchers found the brain encodes the vividness of perceived and real stimuli in a similar manner, resulting in a confusion between reality and imagination.
New Genetic Link to Autism Identified on X Chromosome
Dec 19, 2024 · Abstract. Genetic variants in DDX53 contribute to Autism Spectrum Disorder associated with the Xp22.11 locus. Autism spectrum disorder (ASD) exhibits an ∼4:1 male-to-female sex bias and is characterized by early-onset impairment of social/communication skills, restricted interests, and stereotyped behaviors.
Study Challenges Myths About Cannabis, Brain Health, and IQ
Dec 16, 2024 · Abstract. Cannabis Use and Age-Related Changes in Cognitive Function From Early Adulthood to Late Midlife in 5162 Danish Men. Introduction. Cannabis is by far the most widely used and abused drug listed on the Drug Enforcement Administration’s Schedule I, which includes drugs with a high potential for abuse.
Your Heart’s Secret: It Has Its Own Nervous System
Dec 4, 2024 · Summary: New research reveals the heart has its own complex nervous system, or “mini-brain,” capable of regulating the heartbeat independently of the brain.Conducted on zebrafish, the study identified specialized neurons within the heart, including some with pacemaker properties, challenging traditional views of heartbeat control.
Video Games Boost Cognition, Exercise Improves Mental Health
Oct 19, 2024 · Summary: A large-scale study has found that playing video games boosts cognitive abilities, but has no impact on mental health, while exercise improves mental well-being without affecting cognition.Over 1,000 participants completed cognitive tests after playing video games and completing a lifestyle survey. The results showed that frequent gamers performed cognitively like people 13.7 years ...

A new study has identified three psychological profiles that influence brain health, cognitive decline, and dementia risk in aging adults. Profiles with high protective traits, like purpose and openness, show better cognition and brain integrity, while those with low protective traits or high negative traits face accelerated brain atrophy and mental health issues.
