What primary neurotransmitters are involved in schizophrenia?
Dopamine. Increase in dopemine is a possible cause for schizophrenia.
What Parts of the brain thought to be involved in schizophrenia?
Typically, the temporal lobe and limbic system are involved in schizophrenia. Lesions, malformations, or simply dysfunction in dopaminergic neurons of these areas of the brain can result in the positive and negative symptoms of schizophrenia. Since excess dopaminergic activity is indicative of schizophrenia, antipsychotic drugs that block dopamine receptors are the usual treatment for this illness.
Disorders caused by dopamine?
A lack of dopamine causes Parkinson's disease. As dopamine is an interneuron synaptic neurotransmitter, it controls the passage of impulses along different neurons. If it can't regulate the signal, this leads to frequent involuntary movements as in Parkinson's.
Cocaine stimulates the synapses of specific neurons that release dopamine and other monoamines by?
blocking the dopamine or monoamine reuptake into the presynaptic axon ending
Where is dopamine located?
Dopamine is produced in the substantia nigra of the brain as well as in the ventral tegmental area (VTA) of the midbrain and the arcuate nucleus of the hypothalamus.
What neurotransmitter is associated with schizophrenia?
Schizophrenia is often associated with a high level of the neurotransmitter dopamine.
Schizophrenia is thought to occur when a person has overactivity within this particular neurotransmitter system?
Dopamine is most involved in schizophrenia.
Schizophrenia is related to increased levels of what?
Schizophrenia is related to increased levels of dopamine.
What primary neurotransmitters are involved in schizophrenia?
Dopamine. Increase in dopemine is a possible cause for schizophrenia.
What Parts of the brain thought to be involved in schizophrenia?
Typically, the temporal lobe and limbic system are involved in schizophrenia.

Since excess dopaminergic activity is indicative of schizophrenia, antipsychotic drugs that block dopamine receptors are the usual treatment for this illness.
What disorder is neurotransmitter dopamine closely linked to?
Schizophrenia
Too much of this neurotransmitter can cause schizophrenia?
An over-abundance of dopamine is thought to contribute to the development of schizophrenia.
Schizophrenia may be the result of the overproduction of?
Dopamine. which is a neurotrasmitter in the brain.
Is it true that schizophrenics have an excess of dopamine?
That is one of the theories. The other theory is tied to the function of dopamine. Dopamine inhibits another chemical called GABA. Without any GABA dopamine doesn't really do anything. The other theory is that they have normal levels of Dopamine and low levels of GABA. These theories came about by the observation that anti-dopamine drugs help the symptoms. The simple answer is we're not quite sure yet.
Which of the following statements accurately describes how drugs act on the brain?
Drugs act on the neurons in the reward pathway of the brain. Drugs increase the release of dopamine.
Inhibitors for schizophrenia?
Dopamine or serotonin antagonist e.g. risperidone or amisulpride.
