Coding of periodic pulse stimulation in chemoreceptors.
In natural conditions odorants released continuously by animals and plants are broken in discontinuous clumps and filaments. In the case of flying insects these discontinuities are perceived as periodic variations in the concentration of the stimulus. This periodicity has been shown to be essential to orientation and location of mate and food. We study analytically and numerically a model of th...
متن کاملStimulation of the carotid chemoreceptors of the dog by dopamine.
The mechanisms by which chemosensitive receptors in the carotid body are activated by the changes in the Po2, Pco,, or pH of arterial blood or by a variety of chemicals are still unknown. Physiological activation may require the release of a transmitter substance, formed or stored in Type I chemoreceptor cells, which then excites contiguous sensory nerve endings. Recently, a number of investiga...
متن کاملImproved temporal coding of sinusoids in electric stimulation of the auditory nerve using desynchronizing pulse trains.
Rubinstein et al. [Hearing Res. 127, 108-118 (1999)] suggested that the representation of electric stimulus waveforms in the temporal discharge patterns of auditory-nerve fiber (ANF) might be improved by introducing an ongoing, high-rate, desynchronizing pulse train (DPT). To test this hypothesis, activity of ANFs was studied in acutely deafened, anesthetized cats in response to 10-min-long, 5-...
متن کاملNeural Pulse Coding
Neurons use action potentials to signal over long distances, as summarized in Chapter 1 by Gerstner. The all-or-none nature of the action potential means that it codes information by its presence or absence, but not by its size or shape. In this respect, an action potential can be considered a pulse. This is an important fact about how brains are built, but it is equally important as a theoreti...
متن کاملMicro-pulse Stimulation
This paper deals with a new electrotherapeutic method for use in physiatric treatment. The micro-pulse stimulation is based on the combination of three electrotherapeutic methods: burst therapy, high-voltage pulsed current therapy, and microelectrostimulation. Micro-pulse stimulation is special for its unusual configuration of pulse parameters; high-voltage electric pulses are safely used as a ...
