Abstract
Attention is the primary cognitive process to induce a response to a stimulus. The present study aims at evaluating the activation of different brain regions while performing an attention requiring task. The analysis is achieved with the help of electroencephalography (EEG) recorded simultaneously during the entire period of execution of task. The relative theta and gamma power were significantly higher (p=0.05) during task when compared to rest, whereas in alpha band the relative power was significantly higher (p=0.05) during rest when compared to task. Event related synchronization (ERS) and Event Related Desynchronization (ERD) in relative theta power and relative alpha power respectively was observed particularly in the parietal electrodes (associated with attention). Theta synchronisation and alpha desynchronization is associated with good performance further supported by the task performance with minimal errors. These event-related changes helped sustain attention and visualization of the activated brain regions was accomplished for a better depiction of the findings.
