Potential fluctuations measured in an EEG are mainly generated by pyramidal neurons.
Is it true that potential fluctuations measured in an EEG are mainly generated by pyramidal neurons?
Yes. Potential fluctuations measured in an EEG are primarily generated by the synchronous activity and intracellular currents in the long apical dendrites of cortical pyramidal neurons.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved literature consistently supports the foundational neurophysiological consensus that scalp-recorded EEG potentials and macroscale current dipoles are principally driven by the synaptic activity and intracellular currents flowing through the extensive apical dendrites of cortical pyramidal neurons.
