Teenage bullying linked to lower brain glutamate, early psychosis symptoms

Researchers have found that adolescents being bullied by their peers are at greater risk of the early stages of psychotic episodes and in turn experience lower levels of a key neurotransmitter in a part of the brain involved in regulating emotions.

Study deciphers how misfolded protein drives dopaminergic neuron loss in Parkinson's

A so-called pathological protein long associated with Parkinson's disease has been found in a new study to trigger cells to increase protein synthesis, an event that eventually kills the subset of brain cells that die off in this neurodegenerative condition.

Unlocking the secrets of dopamine-driven learning in the brain

Imagine you're teaching a dog to play fetch. You throw a ball, and your dog sprints after it, picks it up, and runs back. You then reward your panting pup with a treat.

New insights into the cellular programs that promote resolution of inflammation during aging

Aging is associated with chronic, nonresolving inflammation, or "inflammaging," that can lead to tissue dysfunction.

Scientists uncover dopamine's role in learning from rewards and punishments

What happens in the human brain when we learn from positive and negative experiences? To help answer that question and better understand decision-making and human behavior, scientists are studying dopamine.

Cannabis and alcohol co-use disrupts brain development and impairs memory

The increased legalization of cannabis over the past several years can potentially increase its co-use with alcohol. Concerningly, very few studies have looked at the effects of these two drugs when used in combination.

Study finds distinct differences in how the brain releases dopamine in patients with alcohol use disorder

Dopamine is a neurotransmitter that's made in the brain and acts as a chemical messenger, communicating between nerve cells in the brain and the rest of the body.

Study implicates a specific type of brain cell as key player underlying the impact of stressors

More than 70% of adults will experience at least one traumatic experience, such as a life-threatening illness or accident, violent assault or natural disaster, in their lifetimes and nearly a third will experience four or more, according to global data.

Researchers unravel how the brain chemical dopamine relates to schizophrenia

Researchers at the Lieber Institute for Brain Development (LIBD) believe they have solved a riddle that has challenged scientists for more than 70 years: how the brain chemical dopamine relates to schizophrenia, the often-devastating brain disorder characterized by delusional thinking, hallucinations and other forms of psychosis.
