Raw EEG data from a representative subject for the first block of testing for both low- and high-impedance parietal electrode sites in each of the recording environments. Data were downsampled to 10 Hz to illustrate the low-frequency voltage fluctuations over time. The sharp downward spikes are eyeblink artifacts. Note that the data from the high- and low-impedance sites were collected simultaneously, whereas the data from the warm and cool recording environments were collected in separate trial blocks.
