Document Summary
To understand how the mind works, we need to do both behavioural experiments and physiological experiments. Levels of analysis- a topic can be studied in a number of different ways, with each approach contributing to its own dimension of our understanding. Neurons- small units that create and transmit information about what we experience and know. Neuron doctrine- the idea that individual cells transmit signals in the nervous system, and that these cells are not continuous with other cells (cajal) Edgar adrian: recorded electrical signal from single sensory neurons, resting potential- when there are no signals in the neuron, the neuron has a charge of. 70mv more negative than the outside (-70mv = resting potential: nerve impluse- a series of action potentials that are transmitted down the axon due to the stimulation of the receptor. As the impulse passes the recording electrode, the charge inside the axon rises to.
