Figure 2. BOLD fMRI and neuronal activity evoked by sensory stimulation at 9 Hz have different laminar profile.

Figure 2

a. Time courses and amplitudes of BOLD fMRI responses to forepaw stimulation across the cortical depth (mean ± SEM; n=6) demonstrate that hemodynamic responses initiated and had the highest amplitude in laminae II+III. b. Example of evoked LFP responses to forepaw stimulation demonstrates that neuronal responses initiated and had the highest amplitude in lamina IV, and then spread throughout the cortical depth. c. Normalized group results (mean ± SEM) of averaged LFP amplitude (n=5), spiking rates of MUA (n=5), and magnitude of BOLD fMRI (n=6) responses across the cortical depth.
