Researchers report the neural code of the prefrontal cortex is more efficient than the amygdala in both humans and primates. The lower resistance of the amygdala to errors in humans may play a role in exaggerated survival responses, such as those seen in anxiety and PTSD.
Patients with psychosis who have higher levels of an antioxidant called glutathione responded more quickly to medications and had improved outcomes. Researchers estimate a 10% increase in antioxidants could lead to reduced time spent in hospital for those with psychosis.
Researchers identify areas of the brain which help us to plan whether to attack or defend our position.
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.
Yoga has a positive effect on the structure and function of key brain areas associated with memory. Findings provide evidence that yoga may hold promise in mitigating age-related and neurodegenerative decline.
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.
For some, insomnia may be caused by failing to neutralize emotional distress. Researchers speculate the sleep disorder could be caused by brain circuits that regulate emotion.
Neuroimaging reveals areas of the brain associated with visual and auditory processing are more active when anxiety slowly increases during horror movies. After a shocking scene, brain areas associated with emotional processing, threat evaluation, and decision making increase in activity.
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.
