Huntington's disease is a genetically transmitted disease that primarily affects the nervous system. It is characterized by loss of neurons in certain parts of the brain, especially the caudate nucleus and putamen regions. Symptoms typically begin...
The basal ganglia tissue is composed of the caudate nucleus, putamen, and globus pallidus. This area of the brain has a blood supply that can easily be blocked or suffer damage. If blood supply to the any part of the brain is interrupted, the...
Children with ADHD have difficulty paying attention and are hyperactive and impulsive, according to the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-IV-TR). These symptoms are considered diagnosable when they are maladaptive and...

Dopamine is a chemical that your brain and other parts of your body produce to exert various effects throughout your body. The striatum is one part of the brain where dopamine exerts an effect. Disturbances in the actions of dopamine are at the...
Dopamine is a critical neurotransmitter, a chemical that relays nerve impulses through the brain to control diverse processes such as muscle movement, the sensation of pleasure and emotions, and motivation. Conditions such as Parkinson's disease,...
The liver is an organ located just below the diaphragm in humans and is made up of four lobes. The left lobe, right lobe, quadrate lobe and caudate lobe make up the structure of the liver. Each of the lobes of the liver consist of liver lobules,...
Driving requires a person to integrate information from multiple visual and auditory sources. Visual information that needs to be processed includes activity on the road, your mirrors and the instrument display. Similarly, auditory information...
The human body requires proteins to efficiently conduct enzyme and hormonal functions. Insulin, for example, is a protein hormone that regulates blood sugar levels and enhances fatty acids absorption into your baby’s system; fatty acids are...
Obsessive-compulsive disorder, or OCD, is an anxiety-based disorder impacting over three million American adults in a given year, notes Family Doctor. OCD has no single cause, but the presence of this disorder increases the likelihood of having...
Dopamine antagonists are chemicals that occupy dopamine receptors without stimulating them. They thus compete with dopamine for its natural binding sites and hence lower the effects of available dopamine. This can have the same neurological...
Dopamine is a neurotransmitter that the nerves use to send signals. A dopamine deficiency can be the result of trauma, a lack of oxygen, certain medications, toxins and disease. In Parkinson's disease, nerves in an area of the brain that release...
