The Anatomical Record, EarlyView.Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Sperry versus Hebb: Topographic mapping in Isl2/EphA3 mutant mice [PDF]
arXiv, 2008 In wild-type mice axons of retinal ganglion cells establish topographically precise projection to the superior colliculus of the midbrain. This implies that axons of neighboring retinal ganglion cells project to the proximal locations in the target. The precision of topographic projection is a result of combined effects of molecular labels, such as Eph

Aging and Color Vision: A Model Using the Farnsworth‐MUNSELL 100‐Hue Test
Color Research &Application, EarlyView.ABSTRACT Introduction This study examined the theoretical changes in the FM100 Hue scores induced by age‐related changes in the ocular media transmittance. These changes were analyzed with and without a von Kries‐type chromatic adaptation to determine the role of this adaptation process on age‐related changes in hue discrimination.

Metabolically Efficient Codes in The Retina [PDF]
arXiv, 2001 We tested the hypothesis that the neural code of retinal ganglion cells is optimized to transmit visual information at minimal metabolic cost. Under a broad ensemble of light patterns, ganglion cell spike trains consisted of sparse, precise bursts of spikes. These bursts were viewed as independent neural symbols.

Differential response of the retinal neural code with respect to the sparseness of natural images [PDF]
, 2016 Natural images follow statistics inherited by the structure of our physical (visual) environment. In particular, a prominent facet of this structure is that images can be described by a relatively sparse number of features. To investigate the role of this sparseness in the efficiency of the neural code, we designed a new class of random textured ...

Purification and culture of retinal ganglion cells from rodents.
Cold Spring Harbor Protocols, 2013 Here we describe methods for acute purification of retinal ganglion cells (RGCs) from rodent retina by immunopanning, followed by culture in serum-free medium.

Inherited metabolic epilepsies–established diseases, new approaches
Epilepsia Open, EarlyView.Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]
, 2001 Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

InfoMat, EarlyView.Leveraging the modulation effect of oxygen vacancies on the energy barrier, a homogeneously integrated all‐PRC system with tunable temporal dynamics is constructed. The broad range ratio of temporal characteristic (>102) of the reservoir enables PRC to process information across multi‐timescale.
