The analysis of sound frequency and intensity, however, have their origins in the cochlea, and are represented in the pattern of action potential discharges found in auditory nerve fibers.
The investigators also discovered that in the exercise group, measures of vibration perception threshold, nerve distal latency, and nerve action potential amplitude in the lower limbs were more favorable after 4 years than in the control group.
Fostering a prosperous tradition of neuroscience for more than six decades, and supporting numerous future Nobel laureates, it was at the Marine Biological Laboratory that much of the basis of neurophysiology was first described--in marine organisms: retinal neurophysiology, the development and use of the voltage-clamp technique in squid by Cole and Moore (1960), the discovery of the squid giant axon, the elegant analysis of the action potential of the squid giant axon by Hodgkin and Huxley (1952), and the squid giant synapse discovery by Bullock and Harigawa (1957) used for elucidating the mechanisms of synaptic transmission.
