Does an initial phasic response exist in the receptor potential of taste cells?

Physiologica

Summary

The depolarizing receptor potentials to 0.5M NaCl recorded from frog taste cells did not exhibit any phasic response, even when the rectangular waveform of stimulus onset was employed. The quickest depolarizations recorded reached the peak in 50 msec. On the other hand, the gustatory neural response showed initial overshoot of the impulse discharge even when 0.5M NaCl was delivered at the slower rate of 0.06 ml/sec. It is concluded that the initial neural response may be associated with the rate of rise, of the receptor potential before its plateau level is reached.
