Colour coding in the primate retina: diverse cell types and cone-specific circuitry

DM Dacey, OS Packer - Current opinion in neurobiology, 2003 - Elsevier
How is the trichromatic cone mosaic of Old World primates sampled by retinal circuits to
create wavelength opponency? Red-green (L versus M cone) opponency appears to be …

[HTML][HTML] Center surround receptive field structure of cone bipolar cells in primate retina

D Dacey, OS Packer, L Diller, D Brainard, B Peterson… - Vision research, 2000 - Elsevier
In non-mammalian vertebrates, retinal bipolar cells show center-surround receptive field
organization. In mammals, recordings from bipolar cells are rare and have not revealed a clear …

Y-cell receptive field and collicular projection of parasol ganglion cells in macaque monkey retina

JD Crook, BB Peterson, OS Packer… - Journal of …, 2008 - Soc Neuroscience
The distinctive parasol ganglion cell of the primate retina transmits a transient, spectrally
nonopponent signal to the magnocellular layers of the lateral geniculate nucleus. Parasol cells …

Parallel ON and OFF cone bipolar inputs establish spatially coextensive receptive field structure of blue-yellow ganglion cells in primate retina

…, CM Davenport, BB Peterson, OS Packer… - Journal of …, 2009 - Soc Neuroscience
In the primate retina the small bistratified, “blue-yellow” color-opponent ganglion cell
receives parallel ON-depolarizing and OFF-hyperpolarizing inputs from short (S)-wavelength …

Horizontal cell feedback without cone type-selective inhibition mediates “red–green” color opponency in midget ganglion cells of the primate retina

JD Crook, MB Manookin, OS Packer… - Journal of …, 2011 - Soc Neuroscience
The distinctive red–green dimension of human and nonhuman primate color perception
arose relatively recently in the primate lineage with the appearance of separate long (L) and …

The classical receptive field surround of primate parasol ganglion cells is mediated primarily by a non-GABAergic pathway

MJ McMahon, OS Packer, DM Dacey - Journal of Neuroscience, 2004 - Soc Neuroscience
Although the center-surround receptive field is a fundamental property of retinal ganglion
cells, the circuitry that mediates surround inhibition remains controversial. We examined the …

Blue-yellow opponency in primate S cone photoreceptors

OS Packer, J Verweij, PH Li, JL Schnapf… - Journal of …, 2010 - Soc Neuroscience
The neural coding of human color vision begins in the retina. The outputs of long (L)-, middle
(M)-, and short (S)-wavelength-sensitive cone photoreceptors combine antagonistically to …

The smooth monostratified ganglion cell: evidence for spatial diversity in the Y-cell pathway to the lateral geniculate nucleus and superior colliculus in the macaque …

JD Crook, BB Peterson, OS Packer… - Journal of …, 2008 - Soc Neuroscience
In the primate visual system approximately 20 morphologically distinct pathways originate
from retinal ganglion cells and project in parallel to the lateral geniculate nucleus (LGN) and/…

[HTML][HTML] Origins of direction selectivity in the primate retina

…, F Viana, JB Troy, RG Smith, OS Packer… - Nature …, 2022 - nature.com
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 …

Distinct synaptic mechanisms create parallel S-ON and S-OFF color opponent pathways in the primate retina

DM Dacey, JD Crook, OS Packer - Visual neuroscience, 2014 - cambridge.org
Anatomical and physiological approaches are beginning to reveal the synaptic origins of
parallel ON- and OFF-pathway retinal circuits for the transmission of short (S-) wavelength …
