Time/Frequency maps.

<p>Results of the four investigated conditions from a representative contact showing a significant TASK*CONDITION interaction, with SEQ-BIO > SEQ-PHY in the gamma band (electrode F from P8). Time zero indicates the stimulus onset. All frequencies from 8 Hz to 150 Hz are shown. The segregation between alpha, beta and gamma frequency bands is clearly visible. Note the higher gamma power increase during the sequencing of the biological actions.
