Insanity Vs Insanity

Decent Essays

Introduction The defense, Not Guilty by Reasoning of Insanity (NGRI), has been a controversial topic because of the way “insane” is determined. A normal, mentally competent person is able to distinguish between right and wrong because they know consequences and can be remorseful, whereas an “insane” person, a psychopath, is incapable of feeling these things. This brings up the question of how insane criminals should be sentenced compared to a mentally competent one. In the scientific realm, psychiatrists use tests, like the Psychopathy Checklist-Revised, to determine the likeliness of recidivism of a psychopath (Kiehl & Buckholtz). MRI’s can test a psychopath’s brain and show the different characteristics of the prefrontal cortex that alters their emotions and causes the behavioral changes (Sapolski). There are limitations to these examinations and therefore in court, this biological and psychological evidence does not stand as concrete, so some challenge the validity of the insanity plea and is thought as a way to get away with a crime. The judicial system needs to alter the way insanity is defined to fit certain psychological and biological parameters in order to provide a definite ruling.

Psychopathy and Damage to the Prefrontal Cortex In all humans’ brains, the prefrontal cortex (PFC) is the determining factor for empathy, morals, and emotions. The problem comes when the PFC is damaged, which causes alterations in the mental state. University of Wisconsin-Madison’s School of Medicine and Public Health reveals that the damage to this part of the brain is due to reduced structural integrity and less activity in the PFC, determined by diffusor tensor images (DTI) and functional magnetic resonance imaging (MRI). Because doctors determine the behavioral integrity of a person by the function of their PFC, it is the main focus for determining psychopathic tendencies (“Psychopaths’ Brain Show Differences in Structure and Function”). So psychiatrists are now able to examine an MRI of a brain and look at the prefrontal cortex to determine if they have a higher liability of having behavioral inconsistencies or psychopathic qualities, therefore providing a visual confirmation of a mental deformity.
