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.
Yes, an excess of dopamine is associated with schizophrenia.
It is theorized that schizophrenia is associated with an over-abundance of dopamine, so most antipsychotics block dopamine receptors.
An excess of the neurotransmitter dopamine may cause schizophrenia.
Not true .
Dopamine and Serotonin are two neurotransmitters that are important in psychosis
As far as we know, dopamine is the main culprit in psychosis. Autospies have shown excess dopaminergic receptors in the brain's of people who suffered psychosis. Other neurotransmitters are also affected.
Schizophrenics Anonymous was created in 1985.
They are postulated to be 1) excess secretion of dopamine, 2) deficiency of serotonin, and 3) deficiency of norepinephrine (among others).

Mesolimbic pathway - true. It travels from the ventral tegmental area to the nucleus accumbens.
True.
False

Most likely Dopamine which in excess accumulated in the brain cause schizophrenia.
Some are, but most aren't.
