Summary1.Cockroaches (Periplaneta americana) responded to controlled wind puffs with stereotyped turns away from the source of wind. This was followed by running in more varied directions (Fig 3, 5).2.Control experiments indicate that the wind direction, and not other cues from the wind stimulator, provides the directional information for the turn (Fig. 7).3.Cockroaches with the ventral surfaces of their cerci covered were unresponsive to controlled wind puffs. However, covering the dorsal… Expand
The escape behavior of the cockroachPeriplaneta americana
Summary1.The escape response of the cockroachPeriplaneta americana to the predatory strike of the toadBufo marinus was studied by cinematography and stop-frame analysis. Various manipulationsExpand
Escape turning behavior of the cockroach
TLDR
The results are interpreted in terms of the idea that a bilateral comparison of wind evoked GI activity determines the direction of an escape turn: this type of neural integration does not appear to be essential, however, for the determination of the amplitude of an Escape turn. Expand
Responses to wind recorded from the cercal nerve of the cockroachPeriplaneta americana
  • J. Westin
  • Physics, Biology
  • Journal of comparative physiology

TLDR
Responses to wind puffs from different directions were recorded from single sensory neurons in the cercal nerve of this animal to understand better the basis for responses to wind recorded from giant interneurons of the cockroachPeriplaneta americana. Expand
Multisensory control of escape in the cockroach Periplaneta americana
TLDR
The antennae do not represent a primary wind-sensory system, but may have a direct mechanosensory role in escape, and are confirmed in intact animals with restricted wind targeting the cerci or antennae only. Expand
Responses to wind recorded from the cercal nerve of the cockroachPeriplaneta americana
TLDR
The excitatory response peaked during the maximal wind acceleration rather than during maximal wind speed (Fig. 3A), which suggests that the sensory cells may act largely as wind acceleration detectors. Expand
The cockroach's strategy for staying alive
TLDR
Cockroaches minimize their turn when making a towards response, which could represent an effective anti-predator behavior that allows cockroaches to reach one of the preferred ETs within a relatively short time. Expand
Properties of the escape system of cockroaches during walking
TLDR
Adult male cockroaches which were fixed in place but could move their legs normally were presented with wind puffs of different amplitudes and a coherent model of the escape system was developed in which all the known synaptic interactions involving both the ventral and the dorsal GI's have a meaningful role. Expand
Functional recovery from lesions in the escape system of the cockroach
TLDR
Similarities between the recovery in the escape system of the cockroach and behavioral recovery in higher vertebrates are discussed and some general mechanisms that could account for recovery are discussed. Expand
Sensory basis for directional wind detection in first instar cockroaches,Periplaneta americana
TLDR
First instarPeriplaneta americana have only two wind-receptive filiform hair sensilla on each cercus, as compared to over 200 on the cercu of an adult cockroach, and the escape behavior of first instar nymphs, which depends on these sensilla, was oriented away from a source which delivered small puffs of wind. Expand
Behavioral compensation for altered cereal position in the cockroach
TLDR
Intracellular recordings were made from identified giant interneurons in the ventral nerve cord of the cockroach, Periplaneta americana, both before and after the ipsilateral cercus was rotated to point in a new direction to partially compensate for the initial misorientation of turning behavior.

Summary1.Controlled wind puffs of different directions and velocities were delivered to the cerci of cockroaches (Periplaneta americana), while the responses of individually identifiable giantExpand
The sensitivity of hair receptors in caterpillars ofBarathra brassicae L. (lepidoptera, noctuidae) to particle movement in a sound field
TLDR
The conditions of sound—or rather medium vibration—reception in the far-field and in the near-field of sound sources are discussed with reference to possible natural sources of vibrational stimulation for the caterpillars. Expand
The Mauthner-initiated startle response in teleost fish.
TLDR
It is concluded that the fast-body-bend is the direct result of activation of one Mauthner cell and its spinal motor neurone pool and in four species it is described examples of apparently non-Mauthner initiated startle responses. Expand
Reception of medium vibration by thoracal hairs of caterpillars ofBarathra brassicae L. (Lepidoptera, Noctuidae)

  • Journal of comparative physiology
  • 2004
TLDR
A single sensory cell innervates each of the 8 filiform hairs on the thorax of Barathra brassicae caterpillars in a purely phasic fashion, and the medium vibration in the near-field of a flying wasp is an adequate stimulus for the filiform hair. Expand
Pheromone-stimulated locomotory and orientation responses in the American cockroach
TLDR
Following removal of one antenna, the pattern of head and antennal movement changes in a manner which enhances the sweeping of the intact antenna in males of Periplaneta americana, suggesting the possibility of up-wind orientation. Expand
Excitation of Leg motor neurons by giant interneurons in the cockroachPeriplaneta americana
TLDR
Giant interneurons (GI's) of the cockroachPeriplaneta americana were stimulated intracellularly while levator and depressor motor axons of the metathoracic leg were recorded extracellularly, allowing predictions of the response of the motor neurons to different wind directions. Expand
The organization of escape behaviour in the crayfish.
TLDR
Experiments with animals whose nerve cords were cut at various levels indicate that non-giant escape either originates in or is strongly facilitated by the suboesophageal ganglion complex, indicating the normal function of the giant fibres and the general organization of escape behaviour in the crayfish.

TLDR
The structure of the thread-hairs on the cerci of the cockroach Periplaneta american during the intermoult phase has been investigated by scanning and transmission electron microscopy and apparently the oscilliation direction of each thread-hair is determined by the shape of the hair base. 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

TLDR
