Figure 3. Example of the changes in oxyhaemoglobin (ΔoxyHb) and deoxyhaemoglobin (ΔdeoxyHb) recorded from the contralateral and ipsilateral hemispheres in a newborn lamb, together with laser Doppler flowmetry (LDF) measurement from the contralateral cortex and mean arterial pressure (ΔMABP) following a 3.3 Hz stimulus train lasting 4.8 s.

Figure 3

Shaded area shows the period of stimulation. Note increase in LDF measurement, while the changes in oxyHb and deoxyHb are consistent with a ‘negative’ functional response.
