1) Herophilus apparently believed that 'psychic pneuma' was formed in the choroid plexus of the lateral ventricles (out of 'natural pneuma') from where it permeated through to the 4th ventricle (command centre) and activated all nerve action (there being a 'sensory pneuma' for sensory nerves, and 'motor pneuma' for motor nerves).
