Pull request overview
This PR corrects a factual neuroscience error in the EEG chapter by fixing the description of neuronal depolarization (it makes membrane potential move toward 0 mV, i.e., less negative, not more negative).
Changes:
- Update wording in the “What Is EEG?” explanation to state that depolarization makes the cell body less negative.

The "What Is EEG?" section incorrectly described depolarization as making the neuron cell body "more negative" — the opposite of what actually occurs. Depolarization moves the membrane potential toward zero (less negative).
