How specific features in the environment are represented within the brain is an important unanswered question in neuroscience. A subset of retinal neurons, called direction-selective ganglion cells (DSGCs), are specialized for detecting motion along specific axes of the visual field. Despite extensive study of the retinal circuitry that endows DSGCs with(More)

The ability of neuroscience to ascribe functions to brain regions and to different neuronal subtypes within these regions depends on our ability to identify behavioral paradigms that depend on these functions and to measure these behaviors in a quantitative fashion. Due to their inexpensive nature, extensive similarities in brain architecture, availability(More)
Visual response properties of neurons in the dorsolateral geniculate nucleus (dLGN) have been well described in several species, but not in rats. Analysis of responses from the unanesthetized rat dLGN will be needed to develop quantitative models that account for visual behavior of rats. We recorded visual responses from 130 single units in the dLGN of 7(More)
Feedback systems are ubiquitous in neural systems and are a subject of intense theoretical and experimental analysis. Although there exists multiple hypotheses, there is little agreement on their exact function in neural systems. Looking at the thalamo-cortical feedback system as a model for studying feedback in general, I shall model such systems as(More)
