Sensitized by a sea slug: Site-specific short-term and general long-term sensitization in Aplysia following Navanax attack
2022, Neurobiology of Learning and MemoryCitation Excerpt :thereby reducing the probability of the lobster relocating them after it has recovered from the ink/opaline. This post-attack escape behavior by Aplysia reasonably requires full participation of the head and tail to realize maximal speed (Jahan-Parwar & Fredman, 1979; Leonard & Lukowiak, 1984,1986); protracted withdrawal of either is likely to slow the escape. After sufficient distance has been attained by the galloping sea hare, sensitization is adaptively activated to a wide range of stimuli to help protect the once-attacked sea hare from further attacks (Walters, 1991).
A comparison of hatchery-rearing in exercise to wild animal physiology and reflex behavior in Aplysia californica
2018, Comparative Biochemistry and Physiology -Part A : Molecular and Integrative PhysiologyCitation Excerpt :Finally, there may be little similarity between the energetics of vertebrate skeletal muscle and the network of longitudinal and transverse muscle fibers that form the foot muscle of Aplysia. Aplysia TWR recruits foot and tail adherence muscles used in escape locomotion (Jahan-Parwar and Fredman, 1979; Flinn et al., 2001). The same muscles are likely recruited in adherence to the substrate, such as in flume tests.
Modular deconstruction reveals the dynamical and physical building blocks of a locomotion motor program
2015, NeuronCitation Excerpt :To address these issues, we imaged populations of neurons in the pedal ganglion of the sea-slug Aplysia while reliably eliciting its motor program for locomotion. The pedal ganglion contains approximately 1,600 neurons (Cash and Carew, 1989) and wholly contains the rhythmic pattern generator (Jahan-Parwar and Fredman, 1979, 1980), motorneurons (Hening et al., 1979; Fredman and Jahan-Parwar, 1980), and associated neuromodulatory neurons (Hall and Lloyd, 1990; McPherson and Blankenship, 1992) for locomotion, thus making it a tractable target for mapping a motor program to the dynamics and structure of its underlying distributed network. This mixture of systems means that population imaging of the Aplysia pedal ganglion is representative of the analytical challenges that will become increasingly common for large-scale recordings of complex neural systems (Cunningham and Yu, 2014), as we know that the recorded populations will have captured multiple dynamical systems within them.
Neuronal Transcriptome of Aplysia: Neuronal Compartments and Circuitry
2006, CellCitation Excerpt :As with C. elegans, the identified nerve cells in Aplysia form precise connections with one another. Thus, the connections between identified cells of a neural circuit can be mapped on a cell-to-cell basis for a variety of behaviors ranging in complexity from simple withdrawal reflexes to complex fixed action patterns such as locomotion, feeding, and defense reactions (Hening et al., 1979; Jahan-Parwar and Fredman, 1979; Kupfermann, 1974; Kupfermann and Kandel, 1969). Moreover, these behaviors are modulated by various forms of nonassociative and associative forms of learning, as well as by arousal and motivational states (Cleary and Byrne, 1993; Kupfermann and Weiss, 1982; Rosen et al., 1989; Fitzgerald et al., 1997; Kandel, 2001).
