Question

multiple choice question
which terms refers to large, rhythmic voltage changes, resulting from the synchronized activity of the cerebral neurons, that can be recorded by electrodes placed on the scalp?
o brain waves
o membrane potentials
o circadian rhythms
o action potentials

Explanation:

• Brain waves are large, rhythmic voltage changes from synchronized cerebral neuron activity and can be recorded via scalp - placed electrodes.
• Membrane potentials are the electrical potential across a cell membrane (not large - scale, scalp - recordable from cerebral neurons).
• Circadian rhythms are 24 - hour biological cycles (not related to voltage changes from cerebral neurons recorded on the scalp).
• Action potentials are rapid changes in membrane potential of a single neuron (not large - scale, scalp - recordable from synchronized cerebral neurons).

Answer:

brain waves
