Mapping receptive fields in primary visual cortex.
Nearly 40 years ago, in the pages of this journal, Hubel and Wiesel provided the first description of receptive fields in the primary visual cortex of higher mammals. They defined two classes of cortical cells, "simple" and "complex", based on neural responses to simple visual stimuli. The notion of a hierarchy of receptive fields, where increasingly intricate receptive fields are constructed f...
متن کاملReceptive Fields without Spike-Triggering
Stimulus selectivity of sensory neurons is often characterized by estimating their receptive field properties such as orientation selectivity. Receptive fields are usually derived from the mean (or covariance) of the spike-triggered stimulus ensemble. This approach treats each spike as an independent message but does not take into account that information might be conveyed through patterns of n...
متن کاملNeural Encoding II: Reverse Correlation and Visual Receptive Fields
The spike-triggered average stimulus introduced in chapter 1 is a standard way of characterizing the selectivity of a neuron. In this chapter, we show how spike-triggered averages and reverse-correlation techniques can be used to construct estimates of firing rates evoked by arbitrary time-dependent stimuli. Firing rates calculated directly from reversecorrelation functions provide only a linea...
