Retinal ganglion cell topography and spatial resolving power in penguins.
Penguins are a group of flightless seabirds that exhibit numerous morphological, behavioral and ecological adaptations to their amphibious lifestyle, but little is known about the topographic organization of neurons in their retinas. In this study, we used retinal wholemounts and stereological methods to estimate the total number and topographic distribution of retinal ganglion cells in additio...
متن کاملRetinal ganglion cell distribution and spatial resolving power in deep-sea lanternfishes (Myctophidae).
Topographic analyses of retinal ganglion cell density are very useful in providing information about the visual ecology of a species by identifying areas of acute vision within the visual field (i.e. areas of high cell density). In this study, we investigated the neural cell distribution in the ganglion cell layer of a range of lanternfish species belonging to 10 genera. Analyses were performed...
متن کاملOntogenetic changes in retinal ganglion cell distribution and spatial resolving power in the brown-banded bamboo shark
1 2 The development of the visual system in anamniotic vertebrates is a continual process, 3 allowing for ontogenetic changes in retinal topography and spatial resolving power. We 4 examine the number and distribution of retinal ganglion cells in wholemounted retinae 5 throughout the protracted embryonic development (approx. five months) of a chondrichthyan, 6 the brown banded bamboo shark, Chi...
متن کاملOntogenetic changes in retinal ganglion cell distribution and spatial resolving power in the brown-banded bamboo shark Chiloscyllium punctatum (Elasmobranchii).
The development of the visual system in anamniotic vertebrates is a continual process, allowing for ontogenetic changes in retinal topography and spatial resolving power. We examined the number and distribution of retinal ganglion cells in wholemounted retinae throughout the protracted embryonic development (∼5 months) of a chondrichthyan, i.e. the brown-banded bamboo shark Chiloscyllium puncta...
متن کاملRetinal Ganglion Cell Complex in Alzheimer Disease: Comparing Ganglion Cell Complex and Central Macular Thickness in Alzheimer Disease and Healthy Subjects Using Spectral Domain-Optical Coherence Tomography
Introduction: Alzheimer disease (AD) is the most common form of dementia worldwide. The modalities to diagnose AD are generally expensive and limited. Both the central nervous system (CNS) and the retina are derived from the cranial neural crest; therefore, changes in retinal layers may reflect changes in the CNS tissue. Optical coherence tomography (OCT) machine can show delicate retinal layer...
