What is fronto striatal?
Frontostriatal circuits are neural pathways that connect frontal lobe regions with the basal ganglia (striatum) that mediate motor, cognitive, and behavioural functions within the brain. They receive inputs from dopaminergic, serotonergic, noradrenergic, and cholinergic cell groups that modulate information processing.
What does the prefrontal lobe do?
The prefrontal cortex performs functions of cognitive control, and is prominently – though not exclusively – involved in working memory organization via central executive processes.
What is the DMN in the brain?
The default mode network (DMN) is a network of interacting brain regions that is active when a person is not focused on the outside world, measurable with the fMRI technique.
What is the role of the prefrontal cortex in decision making?
The prefrontal cortex also plays a big role in personality development. It helps people make conscious decisions according to their motivations. Over time, this can lead to certain tendencies in behavior, such as a person acting friendly toward others because they want to be popular.
What is the function of striatum?
The striatum is one of the principal components of the basal ganglia, a group of nuclei that have a variety of functions but are best known for their role in facilitating voluntary movement.
What is the cerebellum responsible for?
Maintaining balance: The cerebellum has special sensors that detect shifts in balance and movement. It sends signals for the body to adjust and move. Coordinating movement: Most body movements require the coordination of multiple muscle groups. The cerebellum times muscle actions so that the body can move smoothly.
What role does the default mode network DMN play in consciousness?
In particular, the default mode network (DMN) of the resting brain is thought to be altered by changes in consciousness, including the meditative state. This reflected a trait effect of meditation, highlighting its role in producing durable changes in temporal dynamics of the DMN.
