In the human, visually evoked potentials (VEP) and cerebral oxygenation changes, as
measured by near-infrared spectroscopy (NIRS), are assessed to elucidate the relation …

We evaluated neurovascular coupling during normal aging using visual evoked potentials
(VEPs) and visu-ally evoked cerebral blood flow velocity responses (VEFRs). The …

Neurovascular coupling (NVC) is the temporal and spatial coordination between local
neuronal activity and regional cerebral blood flow. The literature is unsettled on whether age …

We performed an electroencephalography and optical topography study simultaneously
exploring electrophysiological and vascular response magnitude as a function of stimulus …

The relationship between ongoing occipital alpha rhythm (8–12 Hz) and the generation of
visual evoked potentials (VEPs) has been discussed controversially. While the “evoked …

Background and Purpose—During visual stimulation, the increased metabolic demand is
coupled with an increase of cerebral blood flow velocity (pCBFV) in the posterior cerebral …

The high metabolic demand of neuronal tissue, coupled with its relatively low energy
storage capacity, requires that increases in neuronal activation are quickly matched with …

Visual evoked potentials (VEPs) may be analyzed by examination of the morphology of their
components, such as negative (N) and positive (P) peaks. However, methods that rely on …

Gamma Band Activity (GBA) is increasingly studied for its relation with attention, change
detection, maintenance of working memory and the processing of sensory stimuli. Activity …

I. There are many reports of a region of reduced amplitude in the spatial frequency
characteristics of the occipital evoked potential generated by contrast reversing sinusoidal …
