Document Summary
Relat b/w attended stim and person"s perception. Relat b/w an env stim and a neuron"s firing rate. Relat b/w brain activity and a person"s percep. Receptor neurons specialized to transduce specific type of energy. Stim receptor cell body axon. When pressure applied convert to neural resp signal travels down axon next neuron. 4 basic parts: cell body (soma) all of the things that keep the cell alive, dendrites collects signals from other neurons. Appendages that come off the cell body (look like branches: axon (nerve fiber) communicate signal from point a to point b within the neuron. String set of neurons together neural networks. Lots of k+ ions inside of the cell. Lots of na+ ions outside the cell. When neuron is a rest, inside of the cell has electrical potential of -70 mv relative to the outside of the cell. When neuron fires, sodium rushes into cell causing electrical potential to change from -70mv to.
