Nonlinear reverse correlation with synthesized naturalistic noise
نویسندگان
چکیده
Reverse-correlation is the most widely used method for mapping receptive fields of early visual neurons. Wiener kernels of the neurons are calculated by cross-correlating the neuronal responses with a Gaussian white noise stimulus. However, Gaussian white noise is an inefficient stimulus for driving higher-level visual neurons. We show that if the stimulus is synthesized by a linear generative model such that its statistics approximate that of natural images, a simple solution for the kernels can be derived.

The Rate of Information Transfer of Naturalistic Stimulation by Graded Potentials
We present a method to measure the rate of information transfer for any continuous signals of finite duration without assumptions. After testing the method with simulated responses, we measure the encoding performance of Calliphora photoreceptors. We find that especially for naturalistic stimulation the responses are nonlinear and noise is nonadditive, and show that adaptation mechanisms affect...
متن کاملWhat Causes a Neuron to Spike?
The computation performed by a neuron can be formulated as a combination of dimensional reduction in stimulus space and the nonlinearity inherent in a spiking output. White noise stimulus and reverse correlation (the spike-triggered average and spike-triggered covariance) are often used in experimental neuroscience to "ask" neurons which dimensions in stimulus space they are sensitive to and to...
متن کاملMonitoring Depth of Anesthesia by Nonlinear Correlation Measures
Background: Monitoring the depth of anesthesia (DOA) takes an important role for anesthetists in order avoiding undesirable reactions such as intraoperative awareness, prolonged recovery and increased risk of postoperative complications.The Central Nervous System (CNS) is the main target of anesthetic drugs, hence EEG signal processing during anesthesia is helpful for monitoring DOA. In order t...
متن کاملFly Photoreceptors Encode Phase Congruency
More than five decades ago it was postulated that sensory neurons detect and selectively enhance behaviourally relevant features of natural signals. Although we now know that sensory neurons are tuned to efficiently encode natural stimuli, until now it was not clear what statistical features of the stimuli they encode and how. Here we reverse-engineer the neural code of Drosophila photoreceptor...
