D) axonal conductance.

Question

Quizplus · Accepted Answer

Richard Caton's measurement of fluctuations on a voltmeter from electrodes placed on the scalp of a human subject was the first recording of what we now call the electroencephalogram (EEG). The EEG measures the electrical activity of the brain and is commonly used in neuroscience and clinical settings to diagnose and monitor various brain disorders. B) Action potentials are the electrical signals that travel down the axon of a neuron, while D) axonal conductance refers to the movement of ions through the axon. C) Magnetoencephalography (MEG) measures the magnetic fields generated by electrical activity in the brain.
