Spikes: Exploring the Neural Code
Spikes provides a self-contained review of relevant concepts in information theory and statistical decision theory about the representation of sensory signals in neural spike trains and a quantitative framework is used to pose precise questions about the structure of the neural code.
Temporal Contrast Adaptation in the Input and Output Signals of Salamander Retinal Ganglion Cells
Investigation of how the light-evoked input and output signals of salamander retinal ganglion cells adapt to changes in temporal contrast found that adaptation of spike generation to the current variance was attributable to properties of tetrodotoxin-sensitive Na+ channels.

Investigating how the light responses of salamander bipolar cells adapt to changes in temporal contrast found that after an increase in contrast, the onset of adaptation in the bipolar cell had a time constant of 1–2 sec, similar to a fast component of contrast adaptation in that of retinal ganglion cells.
Nonlinear Signal Transfer from Mouse Rods to Bipolar Cells and Implications for Visual Sensitivity
Reading a Neural Code
Here the neural code was characterized from the point of view of the organism, culminating in algorithms for real-time stimulus estimation based on a single example of the spike train, applied to an identified movement-sensitive neuron in the fly visual system.
Network Variability Limits Stimulus-Evoked Spike Timing Precision in Retinal Ganglion Cells
Controlling the Gain of Rod-Mediated Signals in the Mammalian Retina
The primary site of adaptation at low light levels is the synapse between rod bipolar and AII amacrine cells, and noise in the circuitry, rather than rod noise or fluctuations in arriving photons, limits ganglion cell sensitivity at low backgrounds.
Essential role of Ca2+-binding protein 4, a Cav1.4 channel regulator, in photoreceptor synaptic function
Observations indicate that CaBP4 is important for normal synaptic function, probably through regulation of Ca2+ influx and neurotransmitter release in photoreceptor synaptic terminals.
Mechanisms Regulating Variability of the Single Photon Responses of Mammalian Rod Photoreceptors
The spatial structure of a nonlinear receptive field
A mechanistic model based on measurements of the physiological properties and connectivity of only the primary excitatory circuitry of the retina successfully predicts ganglion-cell responses to a variety of spatial patterns and thus provides a direct correspondence between circuit connectivity and retinal output.
