Neuromodulation Changes the Biomechanics and Capabilities of the Aplysia Feeding
INTRODUCTION Neuromodulation is often used by the nervous system to change a muscle’s response to nervous system stimulation. Invertebrate preparations are well suited for study of neuromodulation because of their experimentally tractable nervous systems and biomechanics. The Aplysia smooth muscle I2 is a good model for neuromodulation because it is a muscle with known behavioral correlates [1]...
متن کاملFeeding neural networks in the mollusc Aplysia.
Aplysia feeding is striking in that it is executed with a great deal of plasticity. At least in part, this flexibility is a result of the organization of the feeding neural network. To illustrate this, we primarily discuss motor programs triggered via stimulation of the command-like cerebral-buccal interneuron 2 (CBI-2). CBI-2 is interesting in that it can generate motor programs that serve opp...
متن کاملFeeding biomechanics of juvenile red snapper (Lutjanus
INTRODUCTION Ecomorphological studies are predicated on identifying patterns among morphology, behavioral performance and ecology (Wainwright, 1994), and have been utilized to test a variety of hypotheses concerning the relationships between feeding performance and foraging ecology among teleosts (e.g. Clifton and Motta, 1988; Wainwright, 1996). Ecomorphological studies are also useful in exami...
متن کاملBiomechanics of milk extraction during breast-feeding.
How do infants extract milk during breast-feeding? We have resolved a century-long scientific controversy, whether it is sucking of the milk by subatmospheric pressure or mouthing of the nipple-areola complex to induce a peristaltic-like extraction mechanism. Breast-feeding is a dynamic process, which requires coupling between periodic motions of the infant's jaws, undulation of the tongue, and...
متن کاملRegulation of afferent transmission in the feeding circuitry of Aplysia.
Although feeding in Aplysia is mediated by a central pattern generator (CPG), the activity of this CPG is modified by afferent input. To determine how afferent activity produces the widespread changes in motor programs that are necessary if behavior is to be modified, we have studied two classes of feeding sensory neurons. We have shown that afferent-induced changes in activity are widespread b...
