Different roles of neurons B63 and B34 that are active during the protraction phase of buccal motor programs in Aplysia californica.
TLDR
The buccal ganglion of Aplysia contains a central pattern generator that organizes sequences of radula protraction and retraction during food ingestion and egestion and, despite their similarities, B63 and B34 differ in a number of properties, which reflects their different functions. Expand
B64, a newly identified central pattern generator element producing a phase switch from protraction to retraction in buccal motor programs of Aplysia californica.
TLDR
The firing pattern and synaptic connections of B64 are consistent with the hypothesis that the neuron is part of a central pattern generator underlying buccal motor programs. Expand
Comparative neuroethology of feeding control in molluscs.
TLDR
The conclusions derived from studies on gastropod feeding are generally consistent with those from other systems, but often provide more detailed information on the behavioural function of a particular property of the nervous system. Expand
Identification and characterization of neurons initiating patterned neural activity in the buccal ganglia of Aplysia.
Two patterns of neural activity were identified in excised buccal ganglia of Aplysia californica. Both are expressed in many cells, and each can be expressed independently. Using cells B4 and B5 asExpand
Activity patterns of the B31/B32 pattern initiators innervating the I2 muscle of the buccal mass during normal feeding movements in Aplysia californica.
TLDR
The data indicate that the I2 muscle and the B31/B32 and B61/B62 motor neurons are essential constituents contributing to protraction movements. Expand
Compartmentalization of pattern-initiation and motor functions in the B31 and B32 neurons of the buccal ganglia of Aplysia californica.
TLDR
Data show that the B31/B32 cells serve two functions that are compartmentalized in different regions of the cell and are mediated via different electrical signaling mechanisms, including patterned bursts in the buccal ganglia. Expand
Nitric Oxide Is Necessary for Multiple Memory Processes after Learning That a Food Is Inedible in Aplysia
TLDR
The data indicate that NO signaling during training plays a critical role in the formation of multiple memory processes, and that the substance did not cause a pervasive modulation or poisoning of many aspects of feeding and other behaviors. Expand
Identification of the neural pathway for reinforcement of feeding when Aplysia learn that food is inedible
TLDR
A model is presented suggesting sites of action and mechanisms for learning that foods are edible or inedible in Aplysia, indicating that bilateral nerve sectioning eliminates all stimuli causing negative reinforcement of feeding due to failure to consume food. Expand
Learned changes of feeding behavior in Aplysia in response to edible and inedible foods
TLDR
Feeding behavior in Aplysia fasciata and A. oculifera is modified by pairing the behavior with reinforcing consequences, and animals remain aroused, as shown by low response latency to alternate foods. Expand
Long-Term Memory Requires PolyADP-ribosylation
TLDR
It is suggested that fast and transient decondensation of chromatin structure by polyADP-ribosylation enables the transcription needed to form long-term memory without strand breaks in DNA. Expand
