Magnetic Localization of the Origins of Self-sustained Oscillation in Squid Giant Axons

Noninvasive magnetic recording using toroidal probes were used to measure the distribution of action current in oscillating squid axons. The direction of action current propagation was determined by its polarity during the firstphase of oscillation. Spontaneous and induced oscillation, which differe...

Description
Summary:Noninvasive magnetic recording using toroidal probes were used to measure the distribution of action current in oscillating squid axons. The direction of action current propagation was determined by its polarity during the firstphase of oscillation. Spontaneous and induced oscillation, which differed according to the ratio of salinity in the bathing medium, were observed to originate from the same source. The results showed that the self-sustained oscillatory behavior exhibited by squid giant axons renders more stable spatial order in neural transmission.
