Inferring the Synapse:
· Simple reflex (Sherrington's study) reflex considered in splendid neurological isolation, unaffected by activities elsewhere in the nervous system.
(doesn't exist for even the lowliest spinal reflex is modified by higher centers in the spinal cord or the brain). An itch will initiate a scratch reflex but
if you're the catchman in the trampeze act you'll inhibit it. To remove the effect of higher centers, Sherrington used the spinal animal, usually a dog,
whose spinal cord had been completely severed in the neck region. This cut all the connections between the body and the brain, so that spinal
reflexes could be studied pure.
· Excitation- method simple. Applied mild electric shocks to some point on the spinal animals (spinal dog) skin and observed whether this stimulus
