A population of spiking local interneurons in the metathoracic ganglion of the locust is vigorously excited by particular sensory stimuli from the hindlegs and participates in local postural reflexes. We examined the inputs from singly innervated mechanoreceptors (hairs and campaniform sensilla) to these spiking local interneurons, to nonspiking local interneurons, and to motor neurons that are also elements of local reflex pathways. Recordings were made intracellularly from the interneurons… Expand

TLDR
Staining the central projections of the afferent neurons with dye introduced into their axons at the receptor, and the intracellular injection of dye into motor neurons and interneurons, shows that the branches of all 3 types of neuron overlap in specific regions of neuropile. Expand

TLDR
An anteromedial group of spiking local interneurons in the metathoracic ganglion of the locust is determined to determine the input connections that shape their mechanoreceptive fields on a hindleg and the output connections that define their effects on hindleg motor neurons. Expand

TLDR
The inhibition of spiking local and intersegmental interneurons in the mesothoracic ganglion of the locust Schistocerca gregaria could become significant during walking, where the excitatory and inhibitory inputs to an interneuron are likely to be evoked during the different phases of a step cycle.

TLDR
This article analyzes the mechanisms by which the tactile sensory information from different types of receptor is collated in the CNS so that spatial information is preserved and should enhance sensitivity. Expand
Central organization of common inhibitory motoneurons in the locust: role of afferent signals from leg mechanoreceptors
TLDR
Behavior and electrophysiological results indicate that reflex movements of the leg are accompanied by activity of CI neurons, and it appears that CI activity is inhibited when reflex movement of the legs are actively suppressed by the animal. Expand

TLDR
The responses of a population of spiking local interneurons, with somata at the ventral midline of the metathoracic ganglion, during stimulation of chemo- and mechanoreceptors on the legs of locusts are analyzed. Expand
Single local interneurons in the locust make central synapses with different properties of transmitter release on distinct postsynaptic neurons
TLDR
Results show that quantal contents can vary for the many synapses made centrally by one interneuron, and suggest that this variability may arise from differences in release probabilities between the sites associated with different synapses. Expand
