    Origins of direction selectivity in the primate retina

    From mouse to primate, there is a striking discontinuity in our current understanding of the neural coding of motion direction. In non-primate mammals, directionally selective cell types and circuits are a sig...

    Species-specific wiring for direction selectivity in the mammalian retina

    Directionally tuned signalling in starburst amacrine cell (SAC) dendrites lies at the heart of the circuit that detects the direction of moving stimuli in the mammalian retina. The relative contributions of in...

    Nonlinear dendritic integration of electrical and chemical synaptic inputs drives fine-scale correlations

    Fine-scale synchrony of neural activity determines the nature of neural coding, but its underlying mechanisms are unclear. Here the authors find that coincident electrical and chemical synaptic inputs are nonl...

    Dendritic Computation of Direction in Retinal Neurons

    The retina utilizes a variety of dendritic mechanisms to compute direction from image motion. The computation is accomplished by starburst amacrine cells (SBACs) which are GABAergic neurons presynaptic to dire...

    Maximizing contrast resolution in the outer retina of mammals

    The outer retina removes the first-order correlation, the background light level, and thus more efficiently transmits contrast. This removal is accomplished by negative feedback from horizontal cell to photore...

    Functional architecture of mammalian outer retina and bipolar cells

    ‘Function’ in the outer retina has mainly been studied by recording in situ from single neurons. In lower vertebrates this approach to bipolar cells has been extremely fruitful (e.g. Chapter 12), but in mammals b...

    Measurement of simulation speed: its relation to simulation accuracy

    This article presents an unbiased method for measuring simulation speed for compartmental simulators. The method measures how long it takes to simulate a neural circuit component at a given overall accuracy. B...

    Simulating the foveal cone receptive field

    The foveal midget ganglion cell has a receptive field center fed by one cone. The surround might also be fed by the same center cone since a cone terminal laterally connects to neighboring cones through electr...

    Retinal circuits for daylight: why ballplayers don’t wear shades

    A natural scene contains fine spatial detail at low contrast (Srinivasan et al., 1982), and to represent it as an optical image on the retina requires quite a lot of light This is because the number of photons ar...
