Document Summary
Cognitive neuroscience: study of the physiological basis of cognition. Neurons: building blocks and transmission lines of the nervous system. Nerve net: network that was believed to be continuous, provided a complex pathway for conducting signals uninterrupted through the network. Neuron doctrine: idea that individual cells transmit signals in the nervous system, and that these cells are not continuous with other cells as proposed by nerve net theory. Cell body: contains mechanisms to keep the cell alive. Dendrites: branch out from the cell body to perceive signals from other neurons. Axons/nerve fiber: transmits signals to other neurons. Synapses: small gap in between the end of the neuron"s axon and the dendrites or cell body of another neuron. Neural circuits: neurons are not connected indiscriminately to other, but form connections only to specific neurons, many neurons are connected together to form. Action potential: recorded from an axon in response to 3 levels of pressure stimulation: light, medium and strong.
