The body of knowledge about the human brain is growing exponentially, but questions big and small remain unanswered. Researchers have been using electrode arrays to map electrical activity in different brain regions to understand brain function. Until now, however,...
Many patients with neuropsychiatric disorders such as anxiety or depression experience negative moods that lead them to focus on the possible downside of a given situation more than the potential benefit.
MIT neuroscientists have now pinpointed a brain region that...
A resort vacation provides a strong and immediate impact on molecular networks associated with stress and immune pathways, in addition to short-term improvements in well-being, as measured by feelings of vitality and distress, say researchers.Credit: © Jocelyn / Flickr

These images of mouse brains compare laser scanning photostimulation maps of all the neurons connected to one central neuron in control mice (left) vs. mice dosed with valproic acid (VPA) to induce autism-like symptoms (right). The researchers focused on...
A newly identified protein can be manipulated to make opioid painkillers effective at lower doses while also muting the reward mechanism that leads to addiction, Mount Sinai researchers have found.
The protein, RGSz1 (Regulator of G protein signaling z1), which is...
Childhood bullying inflicts the same long-term psychological trauma on girls as severe physical or sexual abuse, suggests a new survey of college students.
The study, which involved 480 college freshmen through seniors, indicated that the detrimental effects of bullying may...

We use others' eyes - whether they're widened or narrowed - to infer emotional states, and the inferences we make align with the optical function of those expressions, according to new research published in Psychological...
Repeat ketamine infusions decreased -- and for some, eliminated -- suicidal thoughts in outpatients with treatment-resistant depression. Credit: © ryan melaugh / Flickr
Repeat intravenous treatment with low doses of the anesthetic drug ketamine quickly reduced suicidal thoughts in a...
A team of scientists has mapped out how our brains process visuals we don't even know we've seen, indicating that the neuronal encoding and maintenance of subliminal images is more substantial than previously thought.
"Our results indicate that what is...
While measuring brain activity with magnetic resonance imaging during blood pressure trials, UCLA researchers found that men and women had opposite responses in the right front of the insular cortex, a part of the brain integral to the experience...
