John_Mann,
The destruction or alteration of small parts of the brain during life have such a dramatic and profound effect on a person.
The fact that brain injury can alter the self, strongly implies that the brain is the true seat of the self.
The evidence shows that our identity, personality and behaviour are completely determined by the physical configuration of the brain, and that a change to this configuration can alter or eliminate any of them.
The following neurological disorders, for example, provide undeniable evidence that our identity, personality and behaviour are unified with the brain, and can be dramatically influenced by causes beyond our control which affect the brain:

* Anterograde or pure amnesia
* Near-total retrograde amnesia
* Callosal Disconnection
* Alien Hand Syndrome
* Paralysis and Denial
* Capgras’ Syndrome
* The Strange Case of Phineas Gage
* Frontotemporal Dementia
* Euphoria and Emotional “Deadness”
* Psychosis and Depression
* Behavioral Alterations Caused by Tumors
* Akinesia
* Environmental Dependency Syndrome
* Aphasia
* Akinetic Mutism
* Pain asymbolia
* Synesthesia
Brain injury and neurological disorders prove that consciousness is fundamentally a physical phenomenon and that the brain mediates and controls all aspects of consciousness; every part of the mind is entirely dependent on and controlled by the brain.
