Two inhibitory fibres forming synapses with a single nerve cell in the lobster.

摘要: IN the stretch receptors of lobsters described by Alexandrawicz1 dendrites sensory neurons lie in a fine muscle strand. Stretch-deformation passive pull or contraction receptor leads to depolarization and adjacent cell body axon region, thus setting up discharges. In most lobster Alexandrowicz also found two efferent neurons, thick thin ‘accessory’ fibre, forming synapses dendritic region cells. Both accessory fibres divide send one branch slowly adapting neuron other fast (Fig. 1). It has already been shown that stimulation fibre can promptly suppress discharge caused strand2. This therefore specific inhibitory role.
