Arthropods have hair plates that are clusters of mechanosensitive hairs, usually positioned close to joints, which function as proprioceptors for joint movement. We investigated how angular movements of the antenna of the cockroach (Periplaneta americana) are coded by antennal hair plates. A particular hair plate on the basal segment of the antenna, the scapal hair plate, can be divided into three subgroups: dorsal, lateral and medial. The dorsal group is adapted to encode the vertical… Expand
Mechanosensory Control of Antennal Movement by the Scapal Hair Plate in the American Cockroach
TLDR
The results strongly suggest that the S-HP has crucial roles for controlling both spontaneous and stimulated movements of the cockroach antenna. Expand
Proprioceptive input to a descending pathway conveying antennal postural information: Terminal organisation of antennal hair field afferents.
TLDR
Despite the morphological similarity of single mechanoreceptors of aHF and adjacent tactile hairs on the pedicel and flagellum, a clear separation of proprioceptive and exteroceptive mechanosensory neuropils in the cerebral ganglion is found. Expand
The mechanosensory‐motor apparatus of antennae in the Oleander hawk moth (Daphnis nerii, Lepidoptera)
TLDR
A detailed anatomical picture of the antennal mechanosensory‐motor apparatus is provided, which in turn provides key insights into its multifunctional role. Expand
Active touch in orthopteroid insects: behaviours, multisensory substrates and evolution‡
  • C. Comer, Y. Baba

TLDR
Comparisons across Orthoptera suggest an evolutionary model where subtle changes in the architecture of interneurons, and of sensorimotor control loops, may explain differing levels of vision–touch interaction in the active guidance of behaviour. Expand
The neural mechanisms of antennal positioning in flying moths
TLDR
The neural mechanisms of antennal positioning in hawk moths are described from behavioral, neuroanatomical and neurophysiological perspectives, showing that Böhm's bristles control antennals positioning in moths via a reflex mechanism. Expand
Active tactile sensing for localization of objects by the cockroach antenna
  • J. Okada, Y. Toh

TLDR
The performance during tactile orientation can be represented effectively by the frequency with which the antennae touch the attractive objects by three-dimensionally examined in American cockroaches during tethered walking. Expand
Antennal and mouthpart sensilla of Acanthoscelides obtectus say (Coleoptera: Bruchidae)
TLDR
To acquire a better understanding of the sensory orientation of bean weevils, their antennal and palpal sensilla were investigated and were unable to detect any distinct morphological differences between males and females. Expand
The antennal system and cockroach evasive behavior. II. Stimulus identification and localization are separable antennal functions
TLDR
It is indicated that cockroaches acquire basic information on stimulus identity during exploration of surfaces with flagellar receptors, but that basal receptors are triggers for escape behavior. Expand
Visual feedback influences antennal positioning in flying hawk moths
TLDR
Electrophysiological and behavioral evidence is presented to show that, in addition to the Böhm's bristles, antennal muscles of hawk moths also respond to bilateral visual input, which suggests visual feedback may be involved in slower, bilaterally coordinated movements of the antenna during visually guided flight maneuvers. Expand
Encoding of near-range spatial information by descending interneurons in the stick insect antennal mechanosensory pathway.
TLDR
Proprioceptive encoding properties of descending interneurons (DINs) that convey information about antennal posture and movement to the thoracic ganglia are analyzed and how the population of DINs could provide the neural basis for the intersegmental spatial coordinate transfer between a touch sensor of the head andThoracic motor networks is discussed.

The role of antennal hair plates in object-guided tactile orientation of the cockroach (Periplaneta americana)

  • Journal of Comparative Physiology A

TLDR
A group of mechanosensitive hairs on the basal segment of the antenna (scapalhair plate) appears to play a major role in antennal object detection in the horizontal plane, as gauged by shaving off these scapal hair plates. Expand

TLDR
At the level of the J1 joint of each antenna of the rock lobster Palinurus vulgaris a hair plate sensory organ similar to those described in insects has been observed and electrophysiological recordings of the hp sensory nerve correlated with selective mechanical stimulation of individual hairs demonstrated that each hair is innervated by a single sensory fiber.

TLDR
Results suggest that a majority of sense organs on the pedicel and scape of the male cockroach Periplaneta americana are joint mechanoreceptors. Expand
The structure, response properties and development of a hair plate on the mesothoracic leg of the locust.
A hair plate is present on the proximal anterior face of the pro- and mesothoracic tibiae of the legs of the locust Schistocerca gregaria, but not on the metathoracic legs. The hair plate is in aExpand
Central connections of sensory neurones from a hair plate proprioceptor in the thoraco-coxal joint of the locust.
TLDR
It is suggested that these pathways would limit the extent of the swing phase of walking and contribute to the switch to the stance phase in a negative feedback loop that relieves the excitation of the hairs by rotating the coxa backwards. Expand
Proprioceptors and fast antennal reflexes in the ant Odontomachus (Formicidae, Ponerinae)
TLDR
No indication of monosynaptic coupling between the antennal proprioceptive afferents and the trigger motor neurons that release the mandible strike is found, and complex neuronal interactions in the involved neuromeres are more likely to control the timing of the two reflexes. Expand
Properties of the trochanteral hair plate and its function in the control of walking in the cockroach.
TLDR
One function of the trochanteral hair plate is to limit femur flexion during a step cycle to limit overstepping of that leg in a walking animal due to exaggerated flexion of the femur. Expand

The central projections of the cold receptor axons were examined by filling two types of cold receptive sensilla with cobalt lysine on the antennae of the cockroach and appear to form a complex of glomeruli similar to the macroglomerular complex of male moths. Expand
