Barnes shows how the Gulag was … Barnes traces the Gulag experience from its beginnings after …

Mutation of the calcium channel gene Cacna1f disrupts calcium signaling, synaptic transmission and cellular organization in mouse retina

…, WK Stell, F Tremblay, S Barnes… - Human molecular …, 2005 - academic.oup.com
Retinal neural transmission represents a key function of the eye. Identifying the molecular
components of this vital process is helped by studies of selected human genetic eye disorders. …

Ionic channels of the inner segment of tiger salamander cone photoreceptors.

S Barnes, B Hille - The Journal of general physiology, 1989 - rupress.org
Cone photoreceptors were isolated enzymatically and their ionic currents studied by the
whole-cell, gigaseal voltage-clamp technique. Five nonsynaptic currents were identified. A …

Modulation of transmission gain by protons at the photoreceptor output synapse.

S Barnes, V Merchant… - Proceedings of the …, 1993 - National Acad Sciences
Synaptic transmission of the light response from photoreceptors to second-order cells of the
retina was studied with the whole-cell patch-clamp technique in tiger salamander (…

Carbenoxolone inhibition of voltage-gated Ca channels and synaptic transmission in the retina

…, NC Welch, MEM Kelly, S Barnes - Journal of …, 2004 - journals.physiology.org
We show that carbenoxolone, a drug used to block hemichannels in the retina to test the
ephaptic model of horizontal cell inhibitory feedback, has strong inhibitory effects on voltage-…

Cyclic-nucleotide-gated channels mediate synaptic feedback by nitric oxide

A Savchenko, S Barnes, RH Kramer - Nature, 1997 - nature.com
Cyclic-nucleotide-gated (CNG) channels in outer segments of vertebrate photoreceptors
generate electrical signals in response to changes in cyclic GMP concentration during …

The Ca2+ channel antagonists mibefradil and pimozide inhibit cell growth via different cytotoxic mechanisms

…, L Elbaum, C Jollimore, G Rozenberg, S Barnes… - Molecular …, 2002 - ASPET
We show that mitogenic cells expressing T-type Ca 2+ channels (T-channels) are more
sensitive to the antiproliferative effects of the drugs pimozide and mibefradil than cells without …

Proton-mediated feedback inhibition of presynaptic calcium channels at the cone photoreceptor synapse

…, MR Lalonde, WH Baldridge, S Barnes - Journal of …, 2005 - Soc Neuroscience
Generation of center-surround antagonistic receptive fields in the outer retina occurs via
inhibitory feedback modulation of presynaptic voltage-gated calcium channels in cone …

Intrinsic oscillatory activity arising within the electrically coupled AII amacrine–ON cone bipolar cell network is driven by voltage‐gated Na+ channels

…, A Hoggarth, K Johnson, S Barnes… - The Journal of …, 2012 - Wiley Online Library
Key points • In mouse models for retinal degeneration, photoreceptor death leads to
membrane oscillation in the remnant AII amacrine–ON cone bipolar cell network through an …

Modulation of ion channels in rod photoreceptors by nitric oxide

…, LL Moroz, RW Turner, KA Sharkey, S Barnes - Neuron, 1994 - cell.com
Subcellular compartments in the outer retina of the larval tiger salamander were identified as
likely sites of production of nitric oxide (NO), a recently recognized intercellular messenger. …
