Tactile stimuli to a leg of a locust are detected by two classes of exteroceptors: trichoid sensilla (tactile hairs), which are purely mechanoreceptors, and basiconic sensilla, which serve a dual role as mechano- and chemoreceptors. The trichoid sensilla have the longer shafts, but because the two types of receptors are intermingled over the surface of a leg, both can be excited when the leg contacts an obstacle. This article analyzes the mechanisms by which the tactile sensory information from… 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
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.

TLDR
This method of odour stimulation of taste receptors generates less adaptation than direct contact with chemicals, and therefore represents an ideal method for stimulating taste receptors for further studies on the central pathways processing taste signals. Expand
The neurobiology of taste in insects.
TLDR
It is suggested that contact-chemosensory processing by local circuits in the thoracic ganglia directly assesses a chemOSensory quality, that of aversiveness, which is dependent on both chemical identity and concentration and that other chemical qualities such as palatability may be encoded in a similar manner elsewhere in the central nervous system. 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
Gustatory Processing in Thoracic Local Circuits of Locusts
TLDR
G gustatory coding in the relatively simple and accessible nervous system of the locust is analyzed and it is suggested that the aversiveness of a chemical, rather than its identity, is encoded directly in the local circuits. Expand
Multiple Mechanisms for Integrating Proprioceptive Inputs That Converge on the Same Motor Pattern-Generating Network
TLDR
Through a combination of short- and long-lasting, presynaptic and postsynaptic actions, one proprioceptive system is able to promote its impact on a target motor network by biasing the access of a different sensory system to the same circuit. Expand
Wing hair sensilla underlying aimed hindleg scratching of the locust
TLDR
It is concluded that input from forewing tactile hairs plays an important role in eliciting hindleg scratching and encodes the spatial location required for targeting. Expand
External proprioceptors of locust locomotor organs and their change in the course of early larval ontogenesis
TLDR
This work studies topography and structure of such important insect external proprioceptors as campaniform sensillae (CS), essential components of insect posture and locomotion regulation and participate in control of various forms of insect motor behavior. Expand
Neural processing of chemosensory information from the locust legs
TLDR
It could be concluded that chemoreceptors and specially basiconic sensilla on the tarsus, pro and mesothoracic legs play an essential role in identifying the nature of surrounding media which is intern translated as reflexes by the pro and Mesothorcic legs. Expand

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

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

Spinal termination of functionally identified primary afferent neurons with slowly conducting myelinated fibers

Results suggest that there is a highly specialized central projection of primary afferent endings which is related to sensory function and not to fiber diameter, and which receives direct input from cutaneous receptors transmitting activity initiated by innocuous stimulation. Expand

The central arbors of the proleg afferents were examined to determine whether there was an anatomical correlate to the pattern of synaptic strengths and it was found that the somatotopic mapping of afferent arbors may contribute to the specificity of synaptic connections in this system. Expand
