Psychology – Gleitman
What changes instead is the impulse frequency. The stronger the stimulus, the more often the
axon will fire. this effect holds until we reach a maximum rate of firing, after which further increases in intensity have no effect. Different neurons have different
maximum rates; the highest in man is of the order of 1,000 impulses per second.
Interaction between nerve cells:
· Study of reflex : Movements are controlled by spinal cord
· Pierre Cabanis ( wondered whether consciousnrss survives beheading. He concluded it does not and that the body's twitches after execution are mere
reflex actions, automatisms without consciousness. DURING FRENCH REVOLUTION)
· Reflex arc- the reflex pathway that leads from stimulus to response
Inferring the Synapse:
· Simple reflex (Sherrington's study) reflex considered in splendid neurological isolation, unaffected by activities elsewhere in the nervous system.
