The form and time sequence of spikes generated by orthodromic, antidromic, and direct stimulation and during spontaneous activity have been studied with intracellular electrodes simultaneously introduced in the soma and in different parts of the axon of the giant nerve cell of Aplysia. Evidence was obtained that under normal conditions of excitability, the spike originates at some distance from the soma in an axonal region with a higher excitability surpassing that of the surrounding membranes… Expand
Identification of Active Membrane Areas in the Giant Neuron of Aplysia

TLDR
Evidence was obtained that for all modes of stimulation the spike originates in the axon at some distance from the cell body, and that the response of these three parts of the neuron is recorded in the soma as the big or S spike. Expand
Axonal spike generation near the giant neuron soma computed by the Hodgkin-Huxley equation
TLDR
It is suggested that the mechanisms responsible for electrical excitation of the axon are qualitatively and quantitatively similar to those described by Hodgkin and Huxley for the squid axon. Expand
Modes of Initiation and Propagation of Spikes in the Branching Axons of Molluscan Central Neurons
TLDR
Observations of the presence of different sizes of A spikes produced by orthodromic stimulation provide evidence that spikes initiated at separate axonal "trigger zones" of Aplysia neurons may be conducted selectively to the effectors or other neurons innervated by the particular branch. Expand
Regional variations in excitability of barnacle neurons

  • 1984
TLDR
Optical recording techniques using voltage-sensitive dyes were used to examine the initiation and propagation of action potentials within neurons of the supraesophageal ganglion of the giant barnacle, Balanus nubilus, and indicated that some dendrites of these cells are excitable. Expand
AN ELECTROPHYSIOLOGICAL STUDY OF THE ANATOMICAL RELATIONS OF TWO GIANT NERVE CELLS IN APLYSIA DEPILANS.
TLDR
An hypothesis is suggested to account for the presence of the cell bodies of the RGC and LGC in two different ganglia, despite the similarities in branching of their axons, despite their different locations in the adult. Expand
Electrophysiological and morphological properties of type C vagal neurons in the nodose ganglion of the cat.
TLDR
Some passive and active electrical properties of type C neurons were studied intracellularly, in situ, in the nodose ganglia of adult cats and it was shown that the central processes were about four times smaller in diameter than the peripheral processes. Expand
Spike conduction properties of T-shaped C neurons in the rabbit nodose ganglion
TLDR
The study of the refractory periods of the two processes and the application of high frequency stimulation showed that the PP allows higher frequencies than the soma and theCP, and thus that branching and the CP act as low-pass filters. Expand
Electrical Properties of the Pacemaker Neurons in the Heart Ganglion of a Stomatopod, Squilla oratoria
TLDR
Comparison with action potentials caused by axonal stimulation and analysis of time relations indicate that with stronger currents the soma membrane is directly stimulated whereas with weaker currents the impulse first arises in the axon and then invades the Soma. Expand
Patterns of response of neurons in the cerebral ganglion of Aplysia californica.
TLDR
The electrical responses of cells in the cerebral ganglion of Aplysia californica were studied in a whole body preparation and type 1 cells showed little spontaneous activity and fired brief bursts of spikes to a touch. Expand
Soma potential of an interneurone controls transmitter release in a monosynaptic pathway in Aplysia
TLDR
Soma potentials of one interneurone regulate the release of transmitter, possibly by a direct effect on its terminals, and can be sustained beyond the normal time course of the p.p.s. by prolonged depolarisation of the soma. Expand

The site of impulse initiation in a nerve cell of a crustacean stretch receptor
TLDR
Investigation of the site of impulse initiation in the nerve cell of the crustacean stretch receptor concluded that the conducted impulse usually arose in the dendrites or cell body soma, and that only during strong excitation did the impulse arise in the initial portion of the axon. Expand

TLDR
It is concluded that the presence of a positive synaptic potential indicates that the proximal portions of the axons are acting as sources of current for sinks in the region of the dendrites and cell bodies in the cat's optic nerve. Expand
The Path of the Giant Cell Axons in Aplysia depilans

An attempt to determine the factors governing the generation of spike potentials in these three components, and the way in which they are related to the discharge of an impulse down the axon of the motoneurone. Expand

TLDR
The main purpose of the work described in this paper has been to identify the phases of all-ornothing activity attributable to the nodes described by Quilliam & Sato and to see whether all-or-nothing activity occurs in the non-myelinated terminal after mechanical stimulation of the receptor. Expand

STEPS IN THE PRODUCTION OF MOTONEURON SPIKES
TLDR
Curves of the strength of the stimuli required for eliciting small or full spikes have been constructed in a number of conditions and it is assumed that threshold of the major portions of the soma membrane is higher than the threshold ofThe axon, the transition occurring over a finite area near the axon hillock.
