Document Summary
Lecture two, cognitive neuroscience, cognitive psychology, matthew shane, What is cognitive neuroscience: relates cognitive processing to its neural substrate. Some may consider cognitive neuroscience can be considered as an. Information goes downn to cell body and depending on summation and info is sent to axon terminals and info may or may not be carried to dendrites which are the receivers (this happens over and over) Neurons: the building blocks of the nervous system. Neurons: cells specialized to receive and transmit information in the nervous system: each neuron has a cell body, an axon, and dendrites. Myelin: you can think of myelin as insulation. Just like a house that is better insulated keeps heat in better, axons that are. Myelinated keep signals in better: axon is covered by myelin, only some axons have myelin not all, axons with myelin are more efficient, myelin looks white on images (white matter is myelin, gray matter is nt myelin)
