Progress in Retinal and Eye Research, 2012 Ciliary neurotrophic factor (CNTF) is one of the most studied neurotrophic factors for neuroprotection of the retina. A large body of evidence demonstrates that CNTF promotes rod photoreceptor survival in almost all animal models. Recent studies indicate that CNTF also promotes cone photoreceptor survival and cone outer segment regeneration in the ...

Luminance and contrast adaptation of the inner retina [PDF]
, 2015 Adaptation is a common feature of sensory systems, matching neural activity to the range of inputs from the environment. In the visual system this is of great importance because visual stimulus can change across 9 orders of magnitude.

Noise removal at the rod synapse of mammalian retina [PDF]
, 1998 Mammalian rods respond to single photons with a hyperpolarization of about 1 mV which is accompanied by continuous noise. Since the mammalian rod bipolar cell collects signals from 20–100 rods, the noise from the converging rods would overwhelm the ...

Encoding of saccadic scene changes in the mouse retina [PDF]
, 2012 The task of the visual system is to extract behaviourally relevant information from the visual scene. A common strategy for most animals ranging from insects to humans is to constantly reposition gaze by making saccades within the scene. This ‘fixate and

Programmable active pixel sensor to investigate neural interactions within the retina [PDF]
, 2009 Detection of the visual scene by the eye and the resultant neural interactions of the retina-brain system give us our perception of sight. We have developed an Active Pixel Sensor (APS) to be used as a tool for both furthering understanding of these ...

Functional evidence for cone-specific connectivity in the human retina [PDF]
, 2005 NoPhysiological studies of colour vision have not yet resolved the controversial issue of how chromatic opponency is constructed at a neuronal level. Two competing theories, the cone-selective hypothesis and the random-wiring hypothesis, are currently ...

미용 안면 필러 주사 시술 후 발생한 망막하출혈을 동반한 다발성 망막동맥폐쇄의 증례 보고 [PDF]
, 2022 Purpose: Retinal artery occlusion and ciliary artery occlusion (CAO) may occur as complications after cosmetic filler injections. However, submacular and subhyaloid hemorrhage have not been reported after cosmetic filler injection.
