Frontostriatal circuit 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.hese circuits are involved in neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease as well as neuropsychiatric disorders including schizophrenia, depression, obsessive compulsive disorder (OCD) , and attention-deficit hyperactivity disorder (ADHD) .

The Frontal Lobe of the Human Brain The Frontal Lobe. When traumatic brain injury occurs to the frontal area, it is impacting the brain’s largest lobe. Located at the front of each cerebral hemisphere, this lobe is responsible for conscious thought, voluntary movement, and individual personality characteristics.

Frontal Lobes The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990).The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior.here is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990).

- You are here. Areas of the Brain and their Functions. The frontal lobes are part of the Cerebral Cortex and are the largest of the brain's structures. They are the main site of so–called 'higher' Cognitive functions. The frontal lobes contain a number of important substructures, including the prefrontal cortex, orbitofrontal cortex, motor and premotor cortices, and Broca's area.

Dopamine tends to limit and select sensory information arriving from the thalamus to the forebrain.

definitions - Striatumreport a problem The ventral striatum is clearly delineated by tracing the subicular (subiculum) territory. This corresponds to the olfactory tubercle and the nucleus accumbens, which is not a nucleus, but is a striatal part made up of striatal elements. The ventral striatum is generally associated with limbic structures, such as the amygdala, hippocampus, midline thalamus, and certain regions of the prefrontal cortex. In addition, the ventral striatum is strongly innervated by dopaminergic fibers from the ventral tegmental area (VTA), known as the mesolimbic dopamine system, and has the highest density of serotonergic inputs in the striatum. In its present connotation, the term “ventral striatum” was introduced in 1975 by Heimer and ...

Basal ganglia The subthalamic nucleus (STN) is a diencephalic gray matter portion of the basal ganglia, and the only portion of the ganglia that produces an excitatory neurotransmitter, glutamate. The role of the subthalamic nucleus is to stimulate the SNr-GPi complex and it is part of the indirect pathway.

Frontal Lobes The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990). The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior. The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size.

Frontal Lobe Brain Injury Our frontal lobes are the part of the brain that has evolved tremendously as we separated ourselves from the animal kingdom. The large lobes are located basically in our foreheads back to the mid-temple area. The frontal lobes provide the integration of all other brain functions into a seamless whole.

Frontal system FRONTAL SYSTEM - A weather system involving one or more fronts. Commonly used with extratropical storms having warm and cold front regions. A frontal system which forms when a cold front overtakes a warm front. When the air behind the front is cooler than the air ahead, it is called a cold occlusion, when the air ahead is milder, it is a warm occlusion. Offshore. The coastal water zone seaward of inshore waters.

- Frontal lobes are a large brain region representing 30% of the cortical surface. Cerebral cortex can be partitioned in two ways: (1) structurally or (2) functionally. Frontal lobes have three major divisions: motor, premotor, and prefrontal regions.
