Document Summary
The study of the physiological basis of cognition. The idea that a topic can be studied in a number of different ways, with each approach contributing its own dimension to our understanding. We can study the physiology of cognition at levels ranging from the whole. Example of physiological levels of analysis: brain, to structures within the brain, to chemicals that create electrical signals within these structures. Chemical processes neurons activated brain structures activated groups of brain structures activated perception, then later. Chemical processes neurons activated brain storage storage activated. Cells that are the building blocks & transmission lines of the nervous system. A network that can be seen in stained brain tissue under a microscope, which was believed to be continuous. Provides a complex pathway for conducting signals uninterrupted through the network. The idea that individual cells transmit signals in the nervous system, & that these cells are not continuous with other cells as proposed by nerve net theory.
