1- Neuroscience has profoundly expanded our understanding of psychiatric disorders like depression, anxiety, and schizophrenia, illuminating the intricate workings of the brain and its influence on mental health. Neuroimaging techniques such as fMRI and PET scans have allowed researchers to observe brain activity and pinpoint areas implicated in these disorders. For instance, reduced activity in the prefrontal cortex and hyperactivity in the amygdala have been associated with depression and anxiety, shedding light on the neural circuits involved in these conditions (Mayberg, 2003). Similarly, schizophrenia has been linked to abnormal neurotransmitter activity, particularly dopamine dysregulation, which has guided the development of antipsychotic medications (Howes & Kapur, 2009).
