Mechanosensory information from exteroceptive hairs on the legs of a locust is first processed in a segmental ganglion by a midline population of spiking local interneurons for use in adjustments of posture and locomotion. Each interneuron receives excitatory inputs from a characteristic array of these receptors so that the surface of a leg is mapped onto the whole population of interneurons as a series of overlapping receptive fields. The properties of this first synaptic connection, and the… Expand

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

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
Processing of mechanosensory information from gustatory receptors on a hind leg of the locust
TLDR
It is shown that mechanosensory afferents from gustatory receptors form an elaborate detector system with the following properties: they have low threshold displacement angles that decrease with increasing stimulus frequency, they respond phasically to deflections of the receptor shaft and adapt rapidly to repetitive stimulation, and they encode the velocity of the stimulus in their spike frequency.

Correlation between the receptive fields of locust interneurons, their dendritic morphology, and the central projections of mechanosensory neurons

Parallel somatotopic maps of gustatory and mechanosensory neurons in the central nervous system of an insect
TLDR
It is shown that the sensory neurons from tactile hairs form a complete 3‐dimensional somatotopic map in the mesothoracic ganglion, and the position of a receptor on the leg is preserved in the central nervous system not only for the mechanosensory neurons from both tactile hairs and basiconic sensilla but also for chemosENSory neurons.

Transplantation of neurons reveals processing areas and rules for synaptic connectivity in the cricket nervous system.
TLDR
It is concluded that CS can be separated into two classes based on their characteristic axonal projections within each segmental ganglion and that Regenerating sensory neurons can recognize novel postsynaptic neurons if they have dendrites in the appropriate layer of neuropil. Expand
Processing of tactile information in neuronal networks controlling leg movements of the Locust.
TLDR
Recent advances in the understanding of how specific local adjustments of the hind legs of the desert locust, Schistocerca gregaria, are made in response to tactile signals from two different classes of exteroceptor on a leg are reviewed. Expand

TLDR
It is estimated that quantal amplitude of postsynaptic potential amplitude is significantly less than 0.1 mV and that several hundred quanta are released for each presynaptic spike, which accords well with a previous estimate of the number of discrete anatomical synapses and would facilitate modulation of output from the stretch receptor.

Spiking local interneurons as primary integrators of mechanosensory information in the locust.
TLDR
It is concluded that the spiking local interneurons are major elements in the primary integration of inputs from external receptors on the hindlegs, and are involved in at least two types of pathways for local interactions: 1) sensory neuron-spiking local Interneuron-motor neuron, and 2). Expand
