Elevated Dopamine in Cannabis Users May Explain Psychosis Risk
Summary: New research reveals that people with cannabis use disorder (CUD) have elevated dopamine levels in a brain region associated with psychosis, such as schizophrenia. This may help explain why…
Dopamine Clock May Drive Bipolar Mood Swings
Summary: New research suggests that mood swings in bipolar disorder are regulated by two clocks: the body’s 24-hour circadian rhythm and a dopamine-based clock that influences alertness. When these clocks…
Targeting Reward Pathways to Treat Depression
Summary: New research highlights how the brain’s reward-learning system can guide personalized treatments for depression. By studying two brain signals, expected value and prediction error, researchers identified markers that predict…
Dopamine and Serotonin Drive Emotional Word Processing
Summary: Researchers have uncovered how neurotransmitters in the brain respond to the emotional content of language, shedding light on the intersection of emotion, cognition, and communication. Using advanced techniques, the…
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…
