A Bayesian Model of Sensory Adaptation
Recent studies reported two opposite types of adaptation in temporal perception. Here, we propose a bayesian model of sensory adaptation that exhibits both types of adaptation. We regard adaptation as the adaptive updating of estimations of time-evolving variables, which determine the mean value of the likelihood function and that of the prior distribution in a bayesian model of temporal percep...
متن کاملA Bayesian Framework for Sensory Adaptation
Adaptation allows biological sensory systems to adjust to variations in the environment and thus to deal better with them. In this article, we propose a general framework of sensory adaptation. The underlying principle of this framework is the setting of internal parameters of the system such that certain prespecified tasks can be performed optimally. Because sensorial inputs vary probabilistic...
متن کاملAdaptation properties of two types of sensory neurons in a spider mechanoreceptor organ.
The VS-3 slit-sense organs of the tropical wandering spider Cupiennius salei contain two types of mechanosensory neurons with similar morphology but different adaptation properties. We measured the changes in membrane potential produced by mechanical stimulation and by electric current stimulation in a large number of neurons of both types. No significant differences were found between the pass...
متن کاملComplementary control of sensory adaptation by two types of cortical interneurons
Reliably detecting unexpected sounds is important for environmental awareness and survival. By selectively reducing responses to frequently, but not rarely, occurring sounds, auditory cortical neurons are thought to enhance the brain's ability to detect unexpected events through stimulus-specific adaptation (SSA). The majority of neurons in the primary auditory cortex exhibit SSA, yet little is...
