Description:: The mammalian retina harbors more than 30 output channels, each playing a distinct role in processing visual images. A comprehensive understanding of the retinal code primarily relies on the functional knowledge of individual output neurons or retinal ganglion cells (RGCs). Despite recent technical advances in imaging and genetics, the function...

Description:: Melanopsin-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs) represent a class of non-canonical, ganglion cell photoreceptors. These cells influence a variety of visual behaviors including contrast sensitivity, circadian photoentrainment, sleep, and even mood. These wide-ranging behavioral influences are attributed to the multiple subtypes (M1-6) that comprise the ipRGC population, with different...

Description:: In the vertebrate retina, neurons process visual signals, generating feature selectivity in their activity levels. We use computational models to understand these behaviors by interpreting them mathematically. One component of this analysis is the spatial selectivity or receptive field, a property found in all visual sensory neurons. The neurons found...

Description:: The retina does not act as a simple camera, rather visual information goes through multiple layers of processing before it reaches the brain. Retinal ganglion cells (RGCs) are the output neurons of the retina and process visual information in the retina and then project into the brain. There are over...

Description:: The retina detects light, processes the visual signal, and sends a complex set of parallel information channels to the brain via a functionally diverse set of retinal ganglion cells types. This manuscript examines these retinal ganglion cell types, the visual features they encode, and the computational mechanisms leading to their...

Description:: Different features of the visual world are conveyed to the retino-recipient regions of the brain by more than 40 types of retinal ganglion cells (RGCS). Feature detection by RGCs depends on a combination of intrinsic and morphological properties where the interplay of excitatory and inhibitory inputs occurs through local retinal...
