What were the studies of the experimentalists on spinal cord ?
A. 1) The role of spinal cord in nervous control was studied largely by the experimentalists of the sixteenth and seventeenth centuries.
2) They found that the Greeks concept of the brain was erroneous. Animals have shown to have the ability to respond to stimuli even when the brain was removed.
3) The animals still produced muscular movements if it’s skin was pinched or pricked.
4) The observers ‘Leonardo Davinci’ and ‘Stephen Hales’ recorded that the animal died as soon as spinal cord was damaged by pushing a needle down it.
5) It is suggested that, the spinal cord was not simply a trunk road for instructions from the brain but might be a control center in it’s own right.
