Document Summary
Pioneer in the modern scientific study of mind. If the nervous communication be cut off between the brain and other parts, the experiences of those other parts are non-existent for the mind. The eye is blind, the ear deaf, the hand insensible and motionless. And conversely, if the brain be injured, consciousness is abolished or altered, even though every other organ in the body be ready to play its normal part . Damage to the brain associates w/specific changes in mental functioning. Nervous system: network within the body that function to manipulate external and internal info. Specialized for rapid communication of signals throughout the body. The brain: locus of central control in the nervous system. Consists of several hundreds of billions of cells interconnected by hundreds of trillions of connections. Each connections is a locus of signal transfer between cells so cells are always intercommunicating. Brain is made up into 2 general classes of cells : neurons and glia.
