Spherical code of retinal orientation-selectivity enables decoding in ensembled and retinotopic operation

The paper identifies retinal orientation-selective ganglion cell types and shows how their non-orthogonal orientation preferences enable efficient decoding of edge orientations.

Luxotonic signals in human prefrontal cortex as a possible substrate for effects of light on mood and cognition

The paper investigates whether light affects human prefrontal cortex activity through a pathway similar to that in animals, finding luminance-dependent signals in multiple brain regions.

Intrinsically photosensitive retinal ganglion cells evade temporal filtering to encode environmental light intensity

The paper investigates how intrinsically photosensitive retinal ganglion cells (ipRGCs) encode environmental light intensity by showing their unique synaptic drive and resistance to postsynaptic filtering.

Synapse-specific direction selectivity in retinal bipolar cell axon terminals

The paper shows direction selectivity in retinal bipolar cell axon terminals, revealing that directionally-tuned glutamatergic inputs from bipolar cell boutons contribute to direction selectivity before DSGCs.

Synaptic circuits for irradiance coding by intrinsically photosensitive retinal ganglion cells

The paper investigates the synaptic circuits in intrinsically photosensitive retinal ganglion cells (ipRGCs) that encode light intensity, showing that Type 6 ON cone bipolar cells provide the strongest luminance signal.
