Document Summary
Chapter 1 nerve cells + nerve impulses. Biological psychology: the study of the physiological, evolutionary and developmental mechanisms of behaviour + experience. Neuron: brain cell, conveys messages to one another, muscles + glands. 2 founders of neuroscience, charles sherrington + santiago ramon y cajal. Italian camillo golgi found way to stay nerve cells with silver salts, could completely stain some cells while not affecting others. Interneurons cells dendrites + axon are entirely contained within a single structure. Radial glia: guide migration of neurons + axons during embryonic development, when finished, most differentiate into neurons, others into astrocytes + oligodendrocytes. Blood brain barrier protects brain, neurons cannot be replaced as easily as skin/blood cells. This barrier keeps out everything, not functional for any other part of body. Some small, uncharged molecules pass, like vitamins + drugs that affect brain, for others brain uses active transport. Brain needs thiamine (vitamin b1), to use glucose.
