Document Summary
Techniques for recording the brain"s electrical activity include: single-cell recording, electroencephalographic recording, event-related potential recording. Some animal species are preferable to others for studying given behaviours, examples: investigators favor nonhuman primates and cats for recording the single-cell activity of visual functions. These species have excellent vision: barn owl used for studying auditory function. They have excellent hearing and it automatically orients its head to locate the sound of its prey: rats used for recording single-cell activity associated with spatial behaviour. They are small enough to be physically active in a limited space. An electrode that is close to a neuron will provide a large amplitude signal. Graphs for single-cell studies are usually drawn with x-axis scaled on the order of seconds: this allows researchers to correlate the serial action potentials produced by a given neuron with the ongoing behaviour of the animal.
