Transcranial focused ultrasound (tFUS) can help elevate mood and decrease activity in brain networks associated with psychiatric disorders when directed at the ventrolateral prefrontal cortex.
A person's dependency on their smartphone predicts greater loneliness and depressive symptoms, and not the other way around.
An eLife study reveals mantis shrimps have mushroom bodies in the brains. A key player in memory and learning in insects, mushroom bodies have not previously been identified in crustaceans. Researchers believe their finding could shed light on how brain structures evolved in arthropods.
Researchers report we may see similarities between different languages as a result of the brain's preference for efficient information processing.
Using MEG neuroimaging, researchers identify abnormalities in functional activity in brain regions which look structurally normal on conventional MRI scans. The findings could help with early detection of primary progressive aphasia.
Vision appears to play a more dominant role than motor movements when it comes to encoding memory of large-scale spaces. The findings address a long-standing debate as to whether or not body movements aid the learning of physical spaces.
Findings shed light on repulsion, or why the brain treats similar environments as though they are more different than a pair of environments that have nothing in common.
Neurons in the bed nucleus of the stria terminalis (BNST) appear to regulate food intake. The neurons appear to form part of a network that controls appetite loss in mice.
Ten minutes of idle thought can tell us a lot about the potential risk of depression, researchers say. Those who tend to ruminate and were more past or negatively focused in their idle thoughts had an increased risk of depression.
Learning is optimized in computer models when there is an error rate of 15%. Researchers say the 85% accuracy rule may also apply to humans for optimal perceptual learning.
Sleep deprivation increases the levels of serotonin 2A neurotransmitter receptors within 6 - 8 hours. Abnormal serotonin 2A receptor function is associated with hallucinations, cognitive impairment, and is linked to psychiatric disorders such as schizophrenia.
