Question

EEG is the recording of the   _________

(a) signal from axons of the pyramidal cells

(b) signal from the dendrites of the pyramidal cells

(c) cyton secretions

(d) axon secretions

This question was posed to me in homework.

The query is from Electroencephalography in section Diagnostic Investigation in Neurology and Cardiology of Clinical Science

Answer 1

The correct choice is (b) signal from the dendrites of the pyramidal cells

Explanation: Pyramidal cells are those which are close to the surface of the cranium. Dendrites are the extension of cytons, i.e. the cell body of neurons. The dendrites take the impulses, the impulses enter the cyton, travel through the axon and reach the axon terminal from where they are transmitted further.
