Examining Brain-Cognition Effects of Ginkgo Biloba Extract: Brain Activation in the Left Temporal and Left Prefrontal Cortex in an Object Working Memory Task
(a) SSVEP amplitude at the midline prefrontal electrode location Fz. SSVEP amplitude is referenced to the mean SSVEP amplitude averaged over the 10 sec epoch for the post-placebo control task. Note the increased SSVEP amplitude increase during the “hold” component compared with the “intake” component. The GBE related increase in SSVEP amplitude is most prominent during the hold component. (b) SSVEP latency at the midline prefrontal electrode location Fz. SSVEP latency is referenced to the mean SSVEP latency averaged over the 10 sec epoch for the post-placebo control task. In the post-placebo condition, the SSVEP latency reduction during the intake component becomes less prominent during the hold component and reverses to a latency increase at the end of the hold component. Note the SSVEP latency increase associated with the GBE.
