They also are much less likely to cause weight gain and sedation than the older medications. Medications in both classifications work at dealing with schizophrenia, although not every person reacts equally.
Axons
When an electrical impulse travels down a nerve cell's axon, it releases a little chemical copyright called a natural chemical. The copyright mosts likely to the following cell down the line, and triggers it to create a new impulse. Antipsychotic medicines prevent this by blocking particular receptors.

They may help reduce a few of the debilitating signs and symptoms associated with schizophrenia, such as listening to voices, hallucinations and illogical reasoning, and being questionable of others.
They do this by obstructing the dopamine receptors on neurons-- imagine two populaces of brain cells sharing locks, one with D1 and the other with D2 receptors-- so that the drifting dopamine can not bind to these neurons and cause their action. Instead, it obtains reuptaken back right into the presynaptic vesicles and neutralised or ruined by a chemical called monoamine oxidase.
