Future research into the underlying causes of neurological disorders such as autism, epilepsy and schizophrenia, should greatly benefit from a first-of-its-kind atlas of gene-enhancers in the cerebrum (telencephalon). This new atlas identifies and locates thousands of gene-regulating elements in a region of the brain that is of critical importance for cognition, motor functions and emotion.
Using an innovative brain-tracing technique, researchers discover a way to 'untangle' neural networks. The findings offer insight into how specific brain regions are connected.
Researchers have identified a comprehensive circuit mechanism that governs how emotional states can influence movement through connections in the basal ganglia. The mechanism represents a way in which emotional states relate to changes in action control in depression, anxiety, and OCD.
Different types of reward have unique effects on the basal ganglia nuclei. Food rewards influence the left hemisphere of the brain, while erotic rewards engage the right lateral globus and left caudate. Financial rewards engage the basal ganglia bilaterally.
A pathway linking the basal ganglia to the thalamus enhances sensory discrimination and is used to suppress 'background noise'. The pathway, which is controlled by the prefrontal cortex, selectively suppresses sensory input as it flows to the thalamus.
Researchers have successfully recorded neural activity in the human striatum.
According to a new study, disruptions in brain networks can be seen with neuroimaging technology in people with MCI and Parkinson's disease.
