It has been thought that males tend to use their brain hemispheres more laterally than females. However,recent fMRI studies have shown that there may be no difference in brain lateralization between genders.
Functional near-infrared spectroscopy (fNIRS) presents a unique opportunity to acquire real timemeasurements of blood oxygenation changes to observe neural activity specific to the brain’s left and righthemispheres. Using an in-house built multichannel fNIRS system, brain lateralization was observed fromseven males and four females according to specially designed tasks for left and right hemisphere activation.
The Pearson correlation coefficient and a modified Lateralization Index metric for continuous wave fNIRSsystems were calculated to quantify brain lateralization. The preliminary results point to no significantdifference in lateral hemodynamic changes between the genders. However, the correlation of symmetricalchannel pairs decreased as the experiments progressed. To further develop this study, the subject’s performanceand the removal of global interference must be implemented for an improved study of brain lateralization
