Tactile stimulation of the siphon and mantle shelf in Aplysia causes a characteristic withdrawal response of the external organs of the mantle cavity. A similar response also occurs spontaneously. Both responses are mediated by the abdominal ganglion and therefore provide an opportunity for correlating cellular functioning and behavior in a relatively simple and well-studied neuronal system. The withdrawal responses are controlled by five identified motor cells which receive two types of… Expand

The J cells appear to mediate both sensory and modulatory inputs to the circuit for tail withdrawal, and slow EPSPs were associated with an increase in the excitability of the sensory neurons, but no effect of the J cells on spike duration was observed. Expand
Hundreds of neurons in the Aplysia abdominal ganglion are active during the gill-withdrawal reflex
The number of neurons in the Aplysia abdominal ganglion is so large that it may be difficult to determine the role of each activated neuron with presently available experimental tools. Expand
Central and Peripheral Control of Gill Movements in Aplysia
Two types of gill contraction in Aplysia were used to study the relation of peripheral and central pathways in controlling behavioral responses in a mollusk, finding that peripheral pathways are necessary and sufficient for the gill pinnule response. Expand
Habituation and dishabituation mediated by the peripheral and central neural circuits of the siphon of Aplysia.
The siphon withdrawal response evoked by a weak tactile (water drop) or light stimulus is mediated primarily by neurons in the siphon, indicating that the peripheral neural circuit in the isolated siphon can mediate habituation itself, and thus has many of the properties attributed to central neurons.

Respiratory pumping: Neuronal control of a centrally commanded behavior in aplysia
This paper identifies and describes some of the neurons which contribute to the burst generating network in Aplysia californica and focuses on the neurons that produce the synaptic action attributed to Interneurons II and XI. Expand
Distributed Input to the Tail-Siphon Withdrawal Circuit Neurons in the J Cluster of the Cerebral Ganglion in Aplysia from
Plasticity in the circuits for the withdrawal reflexes has been correlated with several simple forms of nonassociative and associative learning in Aplysia, and biochemical, biophysical, and molecularExpand
Stimulus-response relations and stability of mechanoreceptor and motor neurons mediating defensive gill-withdrawal reflex in Aplysia.
Study of the response properties of the sensory and motor neurons of the reflex during repeated stimulation at rates that produce habituation and the stability of the motor responses is described. Expand
Distributed and Partially Separate Pools of Neurons Are Correlated with Two Different Components of the Gill-Withdrawal Reflex in Aplysia
Compared the spike activity of individual neurons in the Aplysia abdominal ganglion with the movement of the gill during the gills-withdrawal reflex, it is shown that a reliable prediction of the position of thegill is achieved only with the combined output of 15–20 neurons, whereas a reliable predictions of the velocity depends on the combinedoutput of 40 or more cells.

The identification and initial characterization of a cluster of command and pattern-generating neurons that subserve respiratory pumping is described, which appears to be a relatively stereotyped behavior that occurs both spontaneously and in response to tactile stimuli, anoxia, food presentation, and changes in illumination.

There is, no known causal connection or correlation between the observed plasticity at the identified synapses in this system and behavioural changes during non‐associative and associative learning paradigms. Expand


Command interneurons in the crayfish central nervous system.
The motor effects evoked by stimulation of each of eight command fibres in the circumoesophageal commissures of the crayfish are described and the responses associated with most of the fibres were not sensitive to the fine temporal pattern of the applied stimulation. Expand
Abstract 1. 1. Five interneurons causing bilateral rhytmic swimmeret movements when stimulated are described with their localizations in the cross-section of the cord between thorax and abdomen. 2.Expand
Stimulation of Egg Laying: Possible Neuroendocrine Function of Bag Cells of Abdominal Ganglion of Aplysia californica
To investigate the possible neurosecretory function of this abdominal ganglion of Aplysia californica, homogenized four ganglia, and injected the material into the haemocoel of a small animal, finding a string of gelatinous material resembling the eggs which are occasionally laid by larger animals.

A circadian locomotor rhythm in Aplysia Californica
Locomotor activity in Aplysia was studied by means of both time-lapse cinematography and a mechanical recorder to find a circadian activity rhythm persisted in a reduced form during a 48 hr period of constant dark. Expand
