Do Quiescence and Wasp Venom-Induced Lethargy Share Common Neuronal Mechanisms in Cockroaches?
It is speculated that the neuronal modulation during the quiescence and venom-induced lethargic states may occur in the central complex and that both states could share a common neuronal mechanism. Expand
Responses of Four Arthropod Prey Species to Mechanosensory, Chemosensory and Visual Cues from an Arachnid Predator: A Comparative Approach
Comparisons of multiple invertebrate prey species to direct predator sensory cues provide insight into the sensory ecology of different species of arthropod. Expand

Students in undergraduate laboratory settings learn many of the foundational principles of sensory processing in the comparatively simple, easy to study invertebrate nervous system through investigations and analyses that work well for this purpose in an undergraduate laboratory. Expand
Strong interactions between spinal cord networks for locomotion and scratching.
In immobilized spinal turtles, simultaneous delivery of types of stimulation could 1) increase the rhythm frequency; 2) evoke switches, hybrids, and intermediate motor patterns; 3) recruit a swim motor pattern even when the swim stimulation was reduced to subthreshold intensity; 4) disrupt rhythm generation entirely.

A Wasp Manipulates Neuronal Activity in the Sub-Esophageal Ganglion to Decrease the Drive for Walking in Its Cockroach Prey
It is shown that by injecting a venom cocktail directly into the SEG, the parasitoid Jewel Wasp selectively manipulates the cockroach's motivation to initiate walking without interfering with other non-related behaviors. Expand
Activation of two forms of locomotion by a previously identified trigger interneuron for swimming in the medicinal leech
It is shown that stimulation of cell Tr1, a previously identified trigger interneuron for swimming in the medicinal leech, can also elicit the motor program for crawling in isolated nerve cords, and that motor choice is independent of the firing frequency of Tr1 and amount of spiking activity.

Suppression of escape behaviour during mating in the cricket Acheta domesticus
It is found that most touch-evoked escape responses are suppressed in copulating males and it is determined that the maxillary palps are another important source of chemosensory information. Expand
Maturation of escape circuit function during the early adulthood of cockroaches Periplaneta americana.
It is concluded that the cockroach escape system undergoes further sensorimotor maturation over a period of 1 month, and that cellular changes correlate with, or predict, some changes in behavioral performance. Expand
The Parasite Moniliformis moniliformis Alters the Escape Response of its Cockroach Host Periplaneta americana
Using the acanthocephalan in the cockroach, it is shown that infected cockroaches experienced a decrease in wind-evoked escape responses, a predator avoidance behavior, that consisted of fewer Escape responses, longer latency and higher threshold for escape behavior. Expand
Descending influences on escape behavior and motor pattern in the cockroach.
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
