Temperature compensation of neuromuscular modulation in aplysia.
Physiological systems that must operate over a range of temperatures often incorporate temperature-compensatory mechanisms to maintain their output within a relatively narrow, functional range of values. We analyze here an example in the accessory radula closer (ARC) neuromuscular system, a representative part of the feeding neuromusculature of the sea slug Aplysia. The ARC muscle's two motor n...
متن کاملSimple mechanism for stabilizing motor output. Focus on "temperature compensation of neuromuscular modulation in aplysia".
The production of distinct and appropriate behaviors under different circumstances requires that an organism’s neural circuitry be flexible and, at times, multifunctional. One means by which neural circuits or networks are accorded flexibility is through the release of neuromodulatory substances by neurons that are actually part of the circuit. This “intrinsic neuromodulation” (Cropper et al. 1...
متن کاملNeuromuscular modulation in Aplysia. I. Dynamic model.
Many physiological systems are regulated by complex networks of modulatory actions. Here we use mathematical modeling and complementary experiments to study the dynamic behavior of such a network in the accessory radula closer (ARC) neuromuscular system of Aplysia. The ARC muscle participates in several types of rhythmic consummatory feeding behavior. The muscle's motor neurons release acetylch...
متن کاملNeuromuscular modulation in Aplysia. II. Modulation of the neuromuscular transform in behavior.
In this work we use mathematical modeling and complementary experiments to study the dynamics of modulation in the accessory radula closer (ARC) neuromuscular system of Aplysia. Here we join a dynamic model of the modulation from the preceding paper to a model of the basal neuromuscular transform (NMT). The resulting complete model of the NMT allows us to predict, test, and analyze the actual m...
متن کاملRole of cAMP in the short-term modulation of a neuromuscular system in aplysia.
Neuromuscular synapses in buccal muscle I3a of Aplysia are modulated by the small cardioactive peptide (SCP), a peptide cotransmitter that is intrinsic to the motor neurons, and by serotonin (5-HT) released from modulatory neurons that are extrinsic to the motor circuit. Although the modulation of excitatory junction potentials (EJPs) and contractions by 5-HT and SCP has been studied extensivel...
