The eyes of the nudibranch mollusc Hermissenda have previously been shown to contain 2 classes of photoreceptors. Type B photoreceptors exhibit increased light responses and membrane excitability after repeated pairings of light and rotation and play an important role in the mediation of associatively produced reductions in phototactic behavior. Type A(More)
Hermissenda crassicornis shows both short- and long-term retention of conditioning following light-rotation pairings. Previous research has shown that prolonged training (50 trials per session, three consecutive daily sessions) produces a suppression of phototaxis lasting for days. This long-term retention reflects associative learning processes, with(More)
In the preceding paper we showed that serotonin mimics the effects of associative conditioning on Type B photoreceptors of Hermissenda. Here we show that serotonin is present in the Hermissenda central nervous system, and that it is released in a calcium-dependent manner. A large number of serotonergic cell bodies are present in the cerebropleural ganglia(More)
Hermissenda's neural and behavioral changes produced by light-rotation pairings were assessed as a function of the temporal relations between visual and vestibular stimulation. The results of in vitro simulations of conditioning indicated that simultaneous pairings (synchronous onsets and offsets of light and caudal hair cell stimulation) resulted in(More)
To determine if serotonin may be involved in associative conditioning-produced changes in the excitability and photoresponses of Type B photoreceptors, isolated nervous systems were exposed to an in vitro conditioning procedure in the presence or absence of drugs that alter normal serotonergic neurotransmission. Pairings of light and intracellular(More)
In this paper, we introduce a novel approach of stability awareness routing for efficient utilization of Bandwidth by use of Bandwidth Threshold. Earlier work on routing in MANETs had resulted in several routing protocols which targets at finding a viable route from source to destination without taking into consideration battery backup or Bandwidth(More)
In this paper, we compare a novel approach of stability awareness routing with stability aware routing for efficient utilization of Bandwidth by use of Bandwidth Threshold. Earlier work on routing in MANETs had resulted in several routing protocols which targets at finding a viable route from source to destination without taking into consideration battery(More)
Bite-strike responses of Hermissenda crassicornis, elicited by chemosensory stimulation of the lips, were found to be modified when food extracts were paired with rotation-produced stimulation of the statocysts. Animals that received repeated pairings of an extract of 1 food (conditioned stimulus, CS) with rotation exhibited suppressed bite-strike responses(More)
