This example calculates and displays ERDS maps of event-related EEG data. ERDS
(sometimes also written as ERD/ERS) is short for event-related
desynchronization (ERD) and event-related synchronization (ERS) [1]_.

:footcite:`PfurtschellerLopesdaSilva1999`.
Conceptually, ERD corresponds to a decrease in power in a specific frequency
band relative to a baseline. Similarly, ERS corresponds to an increase in
power. An ERDS map is a time/frequency representation of ERD/ERS over a range
of frequencies [2]_. ERDS maps are also known as ERSP (event-related spectral
perturbation) [3]_.
of frequencies :footcite:`GraimannEtAl2002`. ERDS maps are also known as ERSP

We use a public EEG BCI data set containing two different motor imagery tasks
available at PhysioNet. The two tasks are imagined hand and feet movement. Our
