Identifying these autoreceptors' vital role in Nov 2, 2024 · Abnormal levels producing too much or too little of the neurotransmitter; Abnormal receptor sensitivity, meaning that the “locks” on neurons aren’t responding properly to dopamine as a “key” Too few receptors, meaning dopamine can interact with fewer neurons; Too many receptors, meaning dopamine can interact with more neurons The dopamine hypothesis of schizophrenia or the dopamine hypothesis of psychosis is a model that attributes the positive symptoms of schizophrenia to a disturbed and hyperactive dopaminergic signal transduction. This illustrates: a. Understanding the roles of dopamine provides insight into these neuropsychiatric conditions. D. Additionally, research has been looking at the receptors sensitivity rather then the “amount” your body makes because the receptors will actually dictate that.
