Figure 3. Original recordings of field potentials and cerebral blood flow in response to different frequencies of stimulation.

Figure 3

Extracellular field potentials (FP) and cerebral blood flow (CBF) in response to variations in stimulus frequency, at a stimulus duration of 8 s, and an intensity of 1.5 mA. The figure shows transformed original records of CBF and FP responses at 6 different frequencies. CBF was measured at an approximate depth of 500–1000 μm and FP at a depth of 700 μm. FP amplitudes are represented by the length of vertical lines above CBF traces that are plotted for each frequency.
