## Overview

eeg-signal-processing covers the full EEG analysis pipeline: from raw multichannel recordings to
interpretable neural measures. It emphasizes principled preprocessing (filtering, re-referencing,
artifact rejection), the major analysis families (ERPs, time-frequency, connectivity), and the
statistical discipline that noisy, high-dimensional EEG data demands.

EEG has millisecond temporal resolution but poor spatial resolution and a terrible signal-to-noise
ratio — most of the work is removing everything that is not brain signal while proving you did not
remove the brain signal too.

## When to use

- Designing an EEG experiment: sampling rate, electrode montage, reference choice, trial counts.
