(2) (2) It was also observed that the projection of cercal sensory fibers in specimens reared with a single cercus differed from normal in that scattered fibers cross the midline in regions of the ganglion where none usually exist.
(3) Both of these interneurons receive excitatory synaptic input from the sensory cells of the nine most prominent columns (a, d, g, f, h, i, k, l, and m) of filiform hairs of the ipsilateral cercus.
(4) The interneurons of three groups of animals were examined; control specimens which were not treated surgically, unilaterally treated specimens which had a single cercus removed and bilaterally treated specimens which had both cerci removed.
(5) The principal afferent input to two identified interneurons was removed by surgically ablating an abdominal sensory appendage, the cercus.
(6) This is due in part to faciliation of an inhibitory synaptic input which is activated by the control cercus.
(7) The most obvious correlate of arbor type is the circumferential position of the hair on the cercus.
(8) It was found that 3 neurons from this system receive the main bulk of excitatory impulsation from the ipsilateral cercus, and only 1 of them--from the contralateral one.
(9) This continuing flexibility of the axonal arbor could also be demonstrated by allowing the amputated cercus to regenerate (Figs.
(10) Passive movements of a cercus, monitored with a position transducer, show that the PAD unit fires discrete bursts during cercal displacement.
(11) The wild-type cercus has two hairs, one lateral (L) and the other medial (M), each with an underlying sensory neuron.
(12) The cercus of the first instar cockroach, Periplaneta americana, bears two filiform hairs, lateral (L) and medial (M), each of which is innervated by a single sensory neuron.
(13) Signal processing in the proposed neural circuit is equivalent to the signal direction estimation by projecting the vector of velocity on the two stable basic directions whose orientations do not change when symmetrical changes in cercus positions occur.
(14) When axons of the sensory neurons were transected during larval development, the cell bodies and the soma-bearing portion of axons, which are located within the cercus, survived but lost their excitability for 9-10 days.
(15) Column "h" afferents were chosen because they make a large contribution to the receptive fields of GIs 1 and 2 after ablation of the contralateral cercus.
(16) The major input to these GIs is from the cercus on the axon side; when this cercus is ablated in the last instar before the adult stage, input from the other cercus becomes more effective within 30 days (Vardi and Camhi, 1982b).
(17) Neural activity in the cercal-to-giant interneurone system was lowered by blocking the movement of the mechanosensitive hairs, located on each cercus, with a facial cleansing cream.3.
(18) First, they had directional sensitivities which were appropriate to their location on the cercus; receptors of this directionality would never be made by the donor tissue if left in its original position.
(19) We have discovered mutant animals that have more hairs on the cercus; the most typical phenotype, called "Space Invader" (SI), has an extra filiform hair in a proximo-lateral position on one of the cerci.
(20) An attempt is made to relate the distribution of filiform hairs on the cercus of the second instar cockroach, Periplaneta americana, to the morphology and patterns of synaptic connectivity of their afferents.
Circus
Definition:
(n.) A level oblong space surrounded on three sides by seats of wood, earth, or stone, rising in tiers one above another, and divided lengthwise through the middle by a barrier around which the track or course was laid out. It was used for chariot races, games, and public shows.
(n.) A circular inclosure for the exhibition of feats of horsemanship, acrobatic displays, etc. Also, the company of performers, with their equipage.
(n.) Circuit; space; inclosure.
