Document Summary
Cognitive neuroscience: the study of the physiological basis of cognition. Taking a physiological approach provides important insights into how the mind works. Neurons: cells that are the building blocks and transmission lines of the nervous system create and transmit information about what we experience and know. During that period could not resolve small details, and without these details, the nerve net appeared to be continuous. Cell body: the metabolic center of the neuron keeps the cell alive. Dendrites: branch out from the cell body is to receive signals from other neurons. Axons (nerve fibers): long processes that transmit signals to other neurons. Synapse: a small gap between the end of a neuron"s axon and the dendrites or cell body of another neuron. Neural circuits: neurons are not connected indiscriminately to other neurons, but form connections only to specific neurons. Receptors: neurons that are specialized to pick up information from the environment (e. g. neurons in the eye, ear, and skin)
