Transcript of Dopamine presentation
Helps regulate movement and emotional responses
Enables us to move towards a reward that we see
Regulates emotional responses and movement What is a Neurotransmitter? Electrical impulses travel down the Axon of a neuron, releasing neurotransmitters as they cross a gap between two neurons - a synapse
Neurotransmitters are the messengers of the body
They transmit information from one neuron to another, ensuring that an electrochemical signal can be passed down the nervous system.
Dopamine is a type of neurotransmitter
It is found in humans and animals, vertebrates or invertebrates Where in the Brain is Dopamine produced? Dopamine is produced in several parts of the brain, including the substantia nigra and ventral tegmantal areas It is then released by the hypothalamus What does a Dopamine deficiency cause? When nerves in the area of the brain that release dopamine (substantia nigra) degenerate, it is a sign of Parkinson's Disease
This is when the patient shakes uncontrollably and muscles of the patient begin to jerk - Movement is a problem
Scientists hypothesize that Restless Leg Syndrome and Periodic Limb Movement Disorder are also caused as a result of a Dopamine deficiency - although these are just hypotheses. Dopamine used as a drug Dopamine can be used as a drug to treat heart conditions
It provides additional strength by stimulating heart muscles
Could also be used to improve kidney blood supply Drugs like cocaine and amphetamine increase levels of dopamine in the brain
High levels of dopamine link a drug users' view of taking the drug to a reward or pleasurable experience
This encourages the user to take drugs again Symptoms of excess Dopamine levels Can cause hallucinations and delusions, marked by the mental illness Schizophrenia
Excess dopamine makes you feel nauseous, and feel as if your tongue is burning
Doctors claim that excess dopamine levels lead to symptoms expressed by schizophrenic people
