Document Summary
No t e b o o k: cognitive psych. Cognitive neuroscience: the study of the physiological basis of cognition, involving an understanding of both the nervous system and the individual units that comprise that system. Cognitive neuroscience aims to understand how the brain represents the world around us and how those representations give rise to our accessible cognitive representations. Levels of analysis: a topic can be understood by studying it at a number of different levels of a system. Neurons: cells that are specialized to receive and transmit information in the nervous system. Each neuron has a cell body, an axon, and dendrites. Nerve net: a network of continuously interconnected nerve fibers, which functions as a continuous network. Neuron doctrine: the idea that individual cells called neurons transmit signals in the nervous system. Cell body: part of a cell that contains mechanisms that keep the cell alive.
