Brain Circuitry Identified That May Be Responsible for Negative Emotional Aspects of Pain

A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.

Behavior Resembling Human ADHD Seen in Dogs

Hyperactivity, impulsivity, and inattention are more common in male dogs and young puppies, researchers say. The findings correspond to age and gender associated with ADHD in humans.

Why Do We Remember Stressful Experiences Better?

Memories of objects from stressful situations rely on similar neural activity to memories of the stressful events themselves.

Genetic Risk for Clinical Depression Linked to Physical Symptoms

Those with a genetic predisposition to clinical depression are more likely to exhibit physical symptoms including migraines, chronic pain, and fatigue, researchers report.

Brain Activity Patterns After Trauma May Predict Long-Term Mental Health

Study finds a link between post-traumatic brain activity and an increase in anxiety symptoms six months after a traumatic event.

Brain Activity Fluctuations May Hold the Keys to Psychiatric Treatment Efficacy

Moment-to-moment fluctuations in brain activity over a three-minute period can reliably predict how receptive a person with social anxiety will be to cognitive behavioral therapy.

A Potential End to Postpartum Depression

Neurosteroid replacement therapy may provide relief of symptoms for new mothers suffering from postpartum depression.

Personality Traits Linked to Hallmarks of Alzheimer’s Disease

A new study adds additional evidence to the link between personality traits and Alzheimer's risk. Researchers found brain changes associated with Alzheimer's are visible early on in people with certain personality traits. Those who scored high for neuroticism and low in conscientiousness were at increased risk of developing Alzheimer's.

Mental Illness Associated With Poor Sleep Quality

People diagnosed with mental health disorders are more likely to report poor sleep quality, including sleep disturbances and problems falling back to sleep, than the general population.

Protein Lactylation Is Induced in the Brain by Neural Activation and Social Stress

In mice, protein lactylation occurs in neurons and is correlated with lactate levels. Protein lactylation is enhanced by neural excitation and social stress. Researchers found social stress specifically enhances lysine lactylation of histone H1 proteins.
