Dopamine Plays Key Role in the Heart’s Stress Response
Summary: Researchers have discovered how stress-induced cardiovascular changes are controlled by the brain. Experiments in rats show that activating the lateral habenula, a stress-sensitive brain region, triggers changes in heart…
Immune System Gene Linked to Hyperactivity, ADHD and Autism
Summary: Researchers have uncovered a link between the immune gene regulator STAT1 and hyperactive behaviors in mice, offering new insights into neurodevelopmental disorders like autism and ADHD. STAT1, vital for…
Childhood Stress Disrupts Attention, Sleep, and Dopamine Balance in Adults
Summary: New research links childhood adversity with later attention deficits, sleep disruptions, and specific dopamine imbalances in the brain. Focusing on critical developmental windows, scientists found that disrupted care early…
Key Biochemical Trigger of Huntington’s Disease Progression Identified
Summary: Researchers have identified a crucial biochemical mechanism that could allow Huntington’s disease to be studied before symptoms appear, offering hope for early intervention. The team found that disrupted dopamine…
Key Brain Protein Tied to Motivation and Mood Identified
Summary: A new study has identified a brain protein, vesicular nucleotide transporter (Vnut), as essential for regulating mood and motivation in mice. When Vnut was removed from brain cells called…
Unexpected Sounds Boost Dopamine, Leading to Riskier Decisions
Summary: A new study shows that unexpected sounds can cause dopamine bursts in the brain, which may lead to riskier decision-making. Researchers found that participants were 4% more likely to…
Hidden Dopamine Neurons Balance Brain Functions and Behavior
Summary: Researchers identified a small group of dopamine neurons in the striatum that play a crucial role in balancing essential brain functions such as reward, cognition, and movement. This discovery…
Study Reveals Dopamine’s Limited Role in Rapid Neural Activity
Summary: A recent study has found that dopamine signals have a minimal impact on rapid neural activity in the striatum, challenging existing theories about dopamine’s role in brain signaling. Using…
