In a new study, 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.

Scientists have proposed a new communication model to explain how brain networks can be navigated to achieve efficient information transfer.

Researchers have discovered another purpose for the gut-brain axis; relaying information to the hippocampus to store information about our environment and location.

A new study reports speech comprehension can improve as much as 10% when sound is delayed relative to vision.

Parkinson’s disease progresses differently in women than in men. A current study has now furnished the first neurophysiological evidence supporting this finding. “Numerous demographic studies have provided evidence that men contract Parkinson’s disease nearly twice as often as women.

A new study reveals the role the anterior cingulate cortex and basolateral amygdala play in observational learning.

Researchers say schizophrenia should not be considered to be just a disorder of the mind, as schizophrenia can also impact other organs. A new study reveals people with schizophrenia often have an over active immune system and other physical disorders.

Transcranial magnetic stimulation allows researchers to better understand how brain networks interact to make word choice decisions.

A new study reveals, in combination with genetics and environmental factors, placenta health during fetal development may play a role in schizophrenia. Researchers report genes associated with schizophrenia may turn on in the placenta during complicated pregnancies.

Researchers report a simple saliva test that measures cortisol levels at specific times of the day, can identify those at risk of stress and depression.

A new study reveals older adults with greater symptoms of depression have a smaller brain volume and a 55% greater chance of vascular lesions in the brain than those who do not have depression.

New research reveals the prefrontal cortex may play a role in coordinating the level of consciousness through the cholinergic system.

Finally this week, researchers report meditation and yoga are more effective at reducing stress than Chi in soldiers. Additionally, those who meditate showed stronger executive control.
