Stress-Like Behaviors Traced to a Single ATP Circuit in the Brain

Summary: New research reveals that reduced ATP signaling in the hippocampus plays a causal role in both depression- and anxiety-like behaviors. In stressed male mice, ATP levels and the ATP-releasing…

Psychedelic ‘Ego Death’ Tied to a Collapse in Alpha Brain Waves

Summary: A new study using DMT as a scientific tool reveals how psychedelics alter the brain’s alpha-wave dynamics and weaken our sense of self. The researchers found that DMT pushes…

Brain Circuit Found to Shape Risk and Impulse Differently by Sex

Summary: Researchers exploring risky decision-making in rats found that a specific reward-related neural circuit influences impulsivity and risk-taking in complex ways that depend on timing and biological sex. Manipulating the…

Triggered Hypothermia Protects the Brain After Injury

Summary: Scientists have discovered a way to induce a hibernation-like state that protects the brain after injury—without using external cooling. By activating a specific population of neurons, researchers created a…

Brain Circuits Show Why Friends’ Lies Are Easier to Believe

Summary: Researchers explored how people process deception from friends versus strangers, using brain imaging to study decision-making in gain and loss contexts. Volunteers were more likely to believe lies in…

Aggression Is Contagious: Observing Violence Primes the Brain for Aggression

Summary: A new study shows that observing violence can make individuals more likely to act aggressively later, but the effect depends on familiarity. Male mice who watched familiar peers attack…

Depression Disrupts Learning to Avoid Unpleasant Events

Summary: Depression specifically impairs the ability to learn how to actively avoid unpleasant events, though it does not affect avoidance behavior once learned. Researchers tested 465 participants across a range…

What You Expect Shapes How Much Pain You Feel

Key Questions Answered Q: How do expectations influence pain perception?A: Expectations shaped by external cues (like visual signals) and those shaped by treatment information (like placebo explanations) both reduce pain,…

Brain Tracks Emotional Transitions Through Music

Summary: New research reveals how the brain navigates emotional transitions, using music as a tool to map changing neural patterns. Scientists found that emotional responses in the brain depend heavily…

Cerebellar Serotonin Acts as a Brake to Reduce Anxiety

Summary: New research reveals that serotonin in the cerebellum plays a crucial role in anxiety regulation. Scientists found that mice with lower cerebellar serotonin levels displayed increased anxiety-like behaviors, while…
