Familial hemiplegic migraine type 2 (FHM2) causes a malfunction of astrocytes in the cingulate cortex. Manipulating astrocytes in the cingulate cortex reversed the disfunction, preventing an increase in migraine-like symptoms in mice carrying the FHM2 defect.
Study reveals how the brain's opioid system is linked to mood changes associated with depression and anxiety. Neuroimaging revealed, in those with depression, there is a decreased number of opioid receptors in specific areas of the brain.
Researchers document neural changes associated with hypnosis.
Researchers have identified a neural link between depression and sleep problems. The study reports brain regions associated with short term memory, self and negative emotions are strongly connected in those with depression, and this may lead to bad sleep quality.
Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes.
Researchers report a single session of transcranial magnetic stimulation can significantly reduce drug cue reactivity for those with substance abuse problems.
Researchers have identified altered gene expression in the prefrontal area of the brain in those with schizophrenia. The study reports schizophrenia may have evolved as 'side effect' of human brain development.
A new study reveals researchers have identified areas of the brain which are different in those who regularly smoke and drink alcohol. Researchers discovered the medial orbitofrontal cortex, an area of the brain implicated in reward, has higher functional connectivity in drinkers. In those who smoke, the lateral orbiotfrontal cortex, an area of the brain linked to impulsive behavior, has lower functional connectivity. The study suggests nicotine may increase overall brain connectivity, which may lead to increased smoking behaviors.
