The escape system of the American cockroach is both fast and directional. In response to wind stimulation both of these characteristics are largely due to the properties of the ventral giant interneurons (vGIs), which conduct sensory information from the cerci on the rear of the animal to type A thoracic interneurons (TIAs) in the thoracic ganglia. The cockroach also escapes from tactile stimuli, and although vGIs are not involved in tactile-mediated escapes, the same thoracic interneurons… Expand
Characterization of tactile-sensitive interneurons in the abdominal ganglia of the cockroach, Periplaneta americana.
TLDR
The results suggest that abdominal tactile-sensitive interneurons are heterogeneous both in anatomical and physiological properties, and that tactile sensitivity was in general consistent with the morphological bias noted in dendritic branch patterns. Expand
Nociceptive Pathway in the Cockroach Periplaneta americana
TLDR
This work examines the nociceptive pathway in an insect, the cockroach Periplaneta americana, from detection of noxious stimuli to nocifensive behavior, and shows thatNoxious stimuli applied to the cuticle of cockroaches evoke responses in sensory axon that are distinct from tactile sensory axons in the sensory afferent nerve.

Rapid mechano-sensory pathways code leg impact and elicit very rapid reflexes in insects
TLDR
The short delays in this mechano-neuronal-muscular pathway from the tip of a leg to the neuromuscular synapses can very rapidly raise muscle tension in the trochanteral depressors at new leg contacts during locust landing and locomotion. Expand
Descending influences on escape behavior and motor pattern in the cockroach.
TLDR
While the thoracic circuitry is sufficient to produce directional escape, lesion or blockage of the connective affects the excitability of components of the escape circuitry, such effects are likely due to the elimination of tonic descending inputs. Expand
Neural Circuit Recording from an Intact Cockroach Nervous System
TLDR
The scope of cockroach sensory modalities that can be used to assay how an insect nervous system responds to environmental perturbations are described. Expand
Identified nerve cells and insect behavior
TLDR
Analysis of neuronal oscillators for rhythmic behavior have delineated a profound influence of sensory feedback on interneuronal circuits: they are not only modulated by feedback, but may be substantially reconfigured. Expand
Deciding Which Way to Go: How Do Insects Alter Movements to Negotiate Barriers?
TLDR
Overall, the studies suggest that CC circuits may indeed influence the descending commands associated with navigational decisions, thereby making them more context dependent. Expand
Cockroach homologs of praying mantis peripheral auditory system components

TLDR
The cuticular metathoracic structures in earless cockroaches that are the homologs to the peripheral auditory components in their sister taxon, praying mantids, are identified and the nature of the cuticular transition from earless to eared in the Dictyoptera is defined. Expand
A Parasitoid Wasp Manipulates the Drive for Walking of Its Cockroach Prey
TLDR
It is reported that the venom, rather than decreasing overall arousal, manipulates neuronal centers within the cerebral ganglia that are specifically involved in the initiation and maintenance of walking. Expand

TLDR
An overview of insect peripheral auditory systems focusing on tympanate ears (pressure detectors) and emphasizing research during the last 15 years is provided, suggesting that the many appearances of hearing could arise from changes in a small number of developmental modules. Expand

Response of thoracic interneurons to tactile stimulation in the cockroach, Periplaneta americana
TLDR
The data suggest that the type-A thoracic interneurons make up a multimodal site of sensory convergence that is capable of generating an oriental escape turn in response to any one of several sensory cues. Expand
Convergence of multi-modal sensory signals at thoracic interneurons of the escape system of the cockroach, Periplaneta americana
TLDR
The results suggest that these type A interneurons serve as a site of convergence for numerous types of sensory activity and suggest that the escape system is capable of responding to directional wind information encoded in the ventral giant interneuron in the context of a wealth of additional information.

The escape behavior of the American cockroach, Periplaneta americana, has provided a large amount of neuroethological data on the control of orientation movements. In the typical behavior, the animalExpand
Wind-activated thoracic interneurons of the cockroach: I. Responses to controlled wind stimulation.
TLDR
This paper examines response properties of various thoracic neurons to wind stimuli originating from different directions and hypothesizes that the presence of VM branches in type A interneurons permits connection with ventral giant interneurs, and this connection accounts for their short latency and directional properties. Expand
Parallel motor pathways from thoracic interneurons of the ventral giant interneuron system of the cockroach, Periplaneta americana.
TLDR
It appears that the TIAs utilize directional wind information from the ventral giant interneurons to make a decision on the optimal direction of escape and the output connections, which project not only to cells within the ganglion of origin but also to adjacent ganglia and perhaps beyond, could allow this decision to be made throughout the thoracic ganglia as a single unit. Expand
Wind-activated thoracic interneurons of the cockroach: II. Patterns of connection from ventral giant interneurons.
TLDR
The data suggest that directional wind fields are primarily the result of selective connection from specific vGIs, and preliminary evidence indicated that left-right homologues do not inhibit one another. Expand
Analysis of proprioceptive inputs to DPG interneurons in the cockroach.
TLDR
The results of this study show that proprioceptive information is processed by DPG interneurons, and all of the DPGInterneuron tested as well as other interneURons receive input from one or more of these proprioceptors. Expand
The structure and function of abdominal stretch receptors in insects
TLDR
In comparing the anatomical features of the various receptor organs, it is pointed out how they can be arranged in a series leading from neurons closely associated with the body wall, to those specialized to register stresses in connective tissue strands which are slung between suitably placed points in the segment, and finally to sensory neurons in closer association with the abdominal musculature.

TLDR
Recent experiments by Wine and Krasne show that a phasic mechanical stimulus to the tail leads to tail flicks that are always mediatecl by lateral giant fiber activity, therefore, the lateral giant is a critical decision fiber for the behavior. Expand
Ventral phasic mechanoreceptors in the cockroach abdomen.
TLDR
A pair of mechanoreceptor organs (ventral phasic receptors) have been found in abdominal segments 2 to 7 in Blaberus craniifer, and probably act as ventilation receptors in intact animals, but other functions are also likely. Expand
