Repetitive firing: quantitative analysis of encoder behavior of slowly adapting stretch receptor of crayfish and eccentric cell of Limulus
Techniques developed for determining summed encoder feedback in conjunction with the leaky integrator and variable-gamma models for repetitive firing are applied to spike train data obtained from the slowly adapting crustacean stretch receptor and the eccentric cell of Limulus. Input stimuli were intracellularly applied currents. Analysis of data from cells stringently selected by reproducibili...
متن کاملRepetitive Firing: Quantitative Analysis of Encoder Behavior of Slowly Adapting Stretch Receptor of Crayfish and Eccentric Cell of Limulus
I N T R O D U C T I O N In the previous paper (Fohlmeister et al., 1977), we established a theoretical f ramework for dealing with encoder feedback in the context of well-defined models. Now we shall apply the techniques developed to formulate a description o f nerve impulse encoder operat ion for two repetitively firing sensory neurons . Previous work on the slowly adapt ing stretch receptor o...
متن کاملAction potential and sodium current in the slowly and rapidly adapting stretch receptor neurons of the crayfish (Astacus astacus).
Action potentials (APs) and sodium current from the slowly and the rapidly adapting stretch receptor neurons in the crayfish (Astacus astacus) were recorded with a two microelectrode voltage- and current-clamp technique. In the rapidly adapting neuron the APs had a duration of 3.2 +/- 0.2 ms (means +/- SE) and an amplitude of 55.2 +/- 1.5 mV. In the slowly adapting receptor neuron APs had a dur...
متن کاملSome effects of receptor muscle contraction on the responses of slowly adapting abdominal stretch receptors of the crayfish.
It has been known for many years that stimulation of the motor nerves to vertebrate muscle spindles leads to an increase in the frequency of discharge of the receptor afferent when the muscle is at a constant length (Matthews, 1933; Leksell, 1945; Kuffler, Hunt & Quilliam, 1951). Recently it has been found in muscle-spindle primary endings of cat and rabbit (Matthews, 1962; Emonet-Denand, Lapor...
متن کاملLung mechanics and activity of slowly adapting airway stretch receptors.
Transpulmonary pressure is thought to be closely associated with slowly adapting mechanoreceptor activity. The transpulmonary pressure required to inflate the lung to a given volume depends on pulmonary compliance: for equal tidal volumes less pressure will be required if compliance is higher. Therefore, an inverse relationship is expected between receptor activity and lung compliance for equal...
