Operant conditioning of head-waving in Aplysia. I. Identified muscles involved in the operant response.
A basic goal in the neurosciences is to understand the cellular mechanisms underlying associative learning. The 2 major forms of associative learning are classical conditioning and operant conditioning. In recent years considerable progress has been made towards a cellular analysis of classical conditioning in a number of different preparations. In contrast, the cellular mechanisms underlying o...
متن کاملOperant conditioning of head-waving in Aplysia. II. Contingent modification of electromyographic activity in identified muscles.
Aplysia can readily exhibit operant conditioning of their head-waving response when bright light is used as aversive reinforcement (Cook and Carew, 1986). In the first paper of this series (Cook and Carew, 1989a), we showed that the electromyographic (EMG) activity of a discrete band of neck muscles, the lateral columellar muscles (LCMs) of Aplysia is significantly correlated with the component...
متن کاملOperant conditioning of head-waving in Aplysia. III. Cellular analysis of possible reinforcement pathways.
Operant conditioning of the head-waving response in Aplysia, as well as conditioning of the electrical activity of identified neck muscles, can be induced readily when bright light is used as aversive reinforcement (Cook and Carew, 1986, 1989b). A cellular analysis of this type of operant conditioning requires an understanding of the neural circuitry that underlies the reinforcement pathways in...
متن کاملOperant conditioning of gill withdrawal in Aplysia.
A basic question in neuroscience is how different forms of learning are related. To further address that question, we examined whether gill withdrawal in Aplysia, which has already been studied extensively for neuronal mechanisms contributing to habituation, sensitization, and classical conditioning, also undergoes operant conditioning. Animals were run in pairs. During the initial training per...
متن کاملIn vitro analog of operant conditioning in aplysia. I. Contingent reinforcement modifies the functional dynamics of an identified neuron.
Previously, an analog of operant conditioning in Aplysia was developed using the rhythmic motor activity in the isolated buccal ganglia. This analog expressed a key feature of operant conditioning, namely a selective enhancement in the occurrence of a designated motor pattern by contingent reinforcement. Different motor patterns generated by the buccal central pattern generator were induced by ...
