Figure 2 - Neuron and muscle cell activities.
2-1, Spontaneous activities of an intact EMNC preparation without stimulation.
2-2, Responses of an intact EMNC preparation evoked by electrical (left column) and mechanical (right column) stimuli.
2-3, Responses of an EMNC preparation evoked by electrical and mechanical stimuli after section of all afferent (left) segmental nerves.
2-4, Responses of an EMNC preparation evoked by electrical and mechanical stimuli after section of all efferent (right) segmental nerves.
2-5, Responses of an EMNC preparation evoked by electrical and mechanical stimuli after section, or partition, of the epidermis-muscle piece.
C, Contraction; N, segmental nerves; Nl, left segmental nerve; Nr, right segmental nerve; E, effector muscle response; M, mechanical stimulus-sensitive neuron response in the nerve cord. Calibration: C, 5 g and 5 s. N, Nl, and Nr, 5 mV and 50 ms. E and M, 50 mV and 50 ms.
