what is the science behind hallucinating voices?

You are hearing the voice of God, it's not science. It's faith.

great well, thanks. is there anything else you would like to add? what is the mechanism by which the hallucination is heard? is it just a random pulse of electrons like a short-circuiting wire?

Basically still unsure, but it's correlated with low grey matter volume, changes in connectivity, lesions on the brain, etc.

We probably keep voices we've already heard before in our memories and using drugs chops and screws them like YouTube videos where they mix and match audio to get soundbites or entire songs that never happened in real life.

When there is increased DA in brain some neurons fire for no reason and brain interprets it as sound. Maybe. Maybe not.

Arnold pls

i think much of the consesnsus is that its due to misattributing your own thought to external influences.

in fact many symptoms of schizophrenia can be seen in terms of misattributions of agency.

a large proportion of schizophrenia hallucinations and delusions seem to stem from things called passivity experiences where people think that outside forces e.g. ufos, cia, god are controlling their thoughts or their actions. contrary to some popular belief, visual hallucinations in schizophrenia are relatively rare, usually not very complex and usually not very distressing.

One increasingly common framework is through prediction error. the brain is a predictive machine (for various reasons) and relies on making predictions of sensory input from the environment in order to function and infer causal structure in the world. Errors in prediction can be used to update inadequate models depending on the certainty (precision) of these errors.

People think that neuroanatomical and neurochemical abnormalities mean that precision of prediction errors are amplified so schizophrenics update models of the world abnormally.

Prediction errors are also suppressed in order to attribute agency. Because a major problem of the brain is how do you differentiate between sensory input caused by yourself and by the rest of the world? By using prediction information from frontal-motor parts of the brain to suppress prediction errors in posterior sensory areas. obviously external influences wont have motor-frontal predictions so external prediction error wont be suppressed in the same way. the easiest example of this you can do on yourself is that you cannot tickle yourself but other people can. this is an example of motor predictions from yourself suppressing sensory information on your body when you tickle yourself.

schizophrenics tend to be able to tickle themselves.
frontal and temporal (where auditory is) means that we dont suppress auditory prediction errors from internal thought properly and misattribute it to the outside world.

internal thought uses the same parts of the brain as when talking outloud and hearing real things in the world. disconnection between frontal and temporal (where auditory is) means that we dont suppress auditory prediction errors from internal thought properly and misattribute it to the outside world. [they also say that neurotransmitters in general (all of them) have a role in modulating precision in prediction errors and prediction which is why they may have a big role too]

people also say dysfunction in frontal parts which is common in schizophrenia may also make it worse and contribute to it because thats involved in monitoring actions and organizing and regulating thought.

this id say is probably the most complete (though not very precise) explanation we have at the moment.

last line meant to say frontal-temporal disconnection means

Never knew god was such a dick

also note, disconnection doesnt necessarily mean a literal physical severing of connections but simply that the brain activity between two different areas are out of sync and this can be for a variety of reasons.
