Document Summary
Sandra witelson (mcmaster) is known for having one of the most extensive collections. Chapter 3: the biological bases of behaviour of preserved human brains: got to study albert einstein"s brain, his brain was alike to all other brains, had a wider parietal region and a distinct sylvian fissure. Communication in the nervous system: behaviour depends on rapid information processing, the nervous system is a complex communication network in which signals are constantly being transmitted, received, and integrated. The neural impulse: using energy to send information: hodgkin and huxley worked with axons in squids 100 x larger than those of humans. The neuron at rest: a tiny battery: neural impulse is a complex electrochemical reaction, resting potential of a neuron is its stable, negative charge when the cell is inactive. The all-or-none law: either the neuron fires or it doesn"t, neurons can convey information about the strength of a stimulus.
