Fig. 3

The figure displayed CSF pressure traces recorded from the same Beagle specimen during electrical stimulation. The traces represent pressure variations in the following regions: the right lateral ventricle (black trace), the right frontal pole (blue trace), the right occipital pole (yellow trace), and the lumbar subarachnoid space (green trace). In addition to CSF pressure, blood pressure and respiration rate were simultaneously recorded. A notable rise in CSF pressure was observed in all monitored regions during electrical stimulation of the OCI. This figure illustrated the synchronized CSF pressure dynamics across multiple regions, providing insights into the systemic response to OCI stimulation. LVP, right lateral ventricle pressure; FPP, right frontal pole pressure; OPP, right occipital pole pressure; LSP, lumbar subarachnoid pressure; BP, blood pressure; R, respiration.
