Keep every channel on its baseline
Fixed-pitch traces make focal changes legible before they become a conclusion.
ELECTROPHYSIOLOGY / REVIEW PRINCIPLES
Read the signal, not the screen
A disciplined window for EEG and implant telemetry review.
LOW <4
ALPHA 8–12
HIGH >32
Read rhythm before amplitude
Delta <4 Hz and theta 4–7 Hz establish the low-frequency floor for review.
Mark alpha without alarming the room
The 8–12 Hz band uses a restrained red reference, not a warning state.
Leave the decision traceable
A ten-second window keeps the time ruler, channel pair, and review note together.
