Study sheds light on how ‘dopamine neurons’ contribute to memory formation in humans

Research sheds light on how the human brain rapidly forms new memories, providing insights into potential new treatments for memory disorders. A new study examined neurons that produce dopamine, a compound that acts as a transmitter for nerve impulses….

Where brain cells get their information may determine their roles in diseases

Scientists find differences in communication pathways to two cell types implicated in psychiatric and movement disorders.

‘Party drug’ could help to treat PTSD

MDMA, the main ingredient in ecstasy, could potentially help individuals with PTSD. A recent trial adds to the evidence but more work is needed.

A rose is a rose is a rose: Mathematical model explains how two brains agree on smells

Scientists have discovered why the brain’s olfactory system is so remarkably consistent between individuals, even though the wiring of brain cells in this region differs greatly from person to person. To make sense of this apparent paradox, the researc…

Could this common diabetes drug prevent cocaine relapse?

A rat study finds that GLP-1 receptor agonists for treating type 2 diabetes and obesity may prevent relapse in cocaine addiction without side effects.

Acute and chronic changes in myelin following mild traumatic brain injury

Preliminary research using mcDESPOT magnetic resonance imaging shows changes in the myelin content of white matter in the brain following mild traumatic brain injury. Myelin changes are apparent at the time of injury and three months afterward.

EEG signals accurately predict autism as early as 3 months of age

Autism is challenging to diagnose, especially early in life. A new study shows that inexpensive EEGs, which measure brain electrical activity, accurately predict or rule out autism spectrum disorder in infants, even in some as young as three months.

Brains of young people with severe behavioral problems are ‘wired differently’

Psychologists and neuroscientists point to subtle differences in brain connectivity impacting young people with conduct disorder.

Youth tackle football participation linked to earlier onset of cognitive and emotional symptoms

Starting to play tackle football before age 12 could lead to earlier onset of cognitive and emotional symptoms among athletes who were diagnosed with CTE and other brain diseases postmortem, according to a new study.

Editing brain activity with holography

The goal of brain implants is to read neuron activity and respond by activating neurons to, for example, move prosthetics or simulate lost perceptions. Researchers have developed a device to do that, projecting a holographic image into the top layer of…
