Electrical stimulation of dopamine neurons alters human learning, offers potential for rehabilitation after injury or addictive behaviors

Stimulation of a certain population of neurons within the brain can alter the learning process, according to a team of neuroscientists and neurosurgeons at the University of Pennsylvania.

Contraception changes affect relationships

Women’s sexual satisfaction in long-term heterosexual relationships may be influenced by changes in hormonal contraceptive use, research from the University of Stirling shows.

Behavioral problems often manifest in children when their preschool teacher is  depressed

Depression in preschool teachers is associated with behavioral problems ranging from aggression to sadness in children under the teachers’ care, new research suggests.

Older migraine sufferers may have more silent brain injury

Older migraine sufferers may be more likely to have silent brain injury. Ischemic silent brain infarctions are symptomless brain injuries and are a risk factor for future strokes. Researchers suggest people who have both migraines and vascular risk fac…

Neurosurgeon uses depth electrodes for speech mapping

Neurosurgical researchers have conducted a small study looking at deep brain electrode implantation as a possible alternative to the traditional WADA test used prior to epilepsy surgery. The WADA test is considered the gold standard for identifying the…

The brain: Key to a better computer

Your brain is incredibly well-suited to handling whatever comes along, plus it’s tough and operates on little energy. Those attributes — dealing with real-world situations, resiliency and energy efficiency — are precisely what might be possible wit…

Dads can parent, too: Neural pathway to parenthood seen in mice

Galanin neurons in the brain’s medial preoptic area that appear to regulate parental behavior, a mouse study finds. If similar neurons are at work in humans, it could offer clues to the treatment of conditions like post-partum depression. “If you look …

This is your brain on meditation: Brain processes more thoughts, feelings during meditation, study shows

Meditation is more than just a way to calm our thoughts and lower stress levels: our brain processes more thoughts and feelings during meditation than when you are simply relaxing, a coalition of researchers has found. “The study indicates that nondire…
