Network Models of Sparse Coding and Nonclassical Receptive Field Effects
Despite decades of research in systems neuroscience, there still exists a fundamental debate over the basis of the neural code and, specifically, what aspects of the neural activity are important for neural computation. Our laboratory has focused on this problem in the context of neural representations of different features in the natural visual world. Through population activity in the visual ...
متن کاملSparse coding of birdsong and receptive field structure in songbirds.
Auditory neurons can be characterized by a spectro-temporal receptive field, the kernel of a linear filter model describing the neuronal response to a stimulus. With a view to better understanding the tuning properties of these cells, the receptive fields of neurons in the zebra finch auditory fore-brain are compared to a set of artificial kernels generated under the assumption of sparseness; t...

متن کاملModeling receptive fields with non-negative sparse coding
An important approach in visual neuroscience considers how the processing of the early visual system is dependent on the statistics of the natural environment. A particularly influential model in this respect has been sparse coding. In this paper we argue for a non-negative variant of the model. This is based partly on neurophysiological grounds and partly on the intuitive understanding of part...
متن کاملVisual Nonclassical Receptive Field Effects Emerge from Sparse Coding in a Dynamical System
Extensive electrophysiology studies have shown that many V1 simple cells have nonlinear response properties to stimuli within their classical receptive field (CRF) and receive contextual influence from stimuli outside the CRF modulating the cell's response. Models seeking to explain these non-classical receptive field (nCRF) effects in terms of circuit mechanisms, input-output descriptions, or ...
