Intracellular activity in cricket neurons during generation of song patterns

摘要: During production of song patterns by the semi-isolated CNS Gryllus campestris, intracellullar recordings were made in fibers mesothoracic ganglion, including synaptic areas identified wing opener and closer motor neurons. The normal calling pattern some transitional songs toward courtship aggression generated absence any phasic sensory timing (Figs. 1, 4).
