• Resumen

  • One area in which humans have made great progress is in discovering the physical or neural correlates of consciousness--what consciousness in the brain "looks like." One way to investigate is to see what changes when consciousness is reduced or absent, as happens when people are in a vegetative state, with no sign of awareness. Brain scans show that such people usually have damage to the thalamus, a relay center located smack-bang in the middle of the brain. Another common finding is damage to the connections between the thalamus and the prefrontal cortex, a region at the front of the brain, generally responsible for high-level complex thought. Brain scanning reveals that three areas of the brain play a pivotal role. Here, Bor discusses the theory of consciousness also known as the global neurons workspace model.
