At LANEBI, we performed the recording of electroencephalographic (EEG) activity to study patterns of brain activity. In this technique, we place electrodes on specific regions of the scalp, allowing us to record "how" clusters of neurons in our brain are working and communicating under different conditions (eg, in resting condition or in cognitive activity).
The evaluation lasts approximately 2h30min and is preferably performed in the morning. Registration is done with the individual sitting in resting conditions, with eyes open and closed. The evaluation requires prior preparation, such as avoiding sleep deprivation and the consumption of stimulants.
NOTE: EEG is a non-invasive technique, so it does not involve perforations or cuts. The electrodes are positioned on the scalp only using a conductive paste that assists in the registration.
Each region of our brain acts differently in response to specific stimuli. In addition, the functionality of these regions may be altered in the face of different cognitive tasks and emotional states. This dynamic is reflected in the oscillations recorded by the electrodes and visualized on the computer. These oscillations can be analyzed mathematically, allowing us to study the functioning of the brain and to represent it visually through topographic maps.
