Ephaptic communication in the vertebrate retina

Autor: Rozan eVroman, Lauw J Klaassen, Maarten eKamermans

Publikováno v: Frontiers in Human Neuroscience, Vol 7 (2013)

In the vertebrate retina, cones project to the horizontal cells (HCs) and bipolar cells (BCs). The communication between cones and horizontal cells uses both chemical and ephaptic mechanisms. Photoreceptors release glutamate in a Ca2+-dependent manne

In the vertebrate retina, horizontal cells generate the inhibitory surround of bipolar cells, an essential step in contrast enhancement. For the last decades, the mechanism involved in this inhibitory synaptic pathway has been a major controversy in

The functional and morphological connectivity between various horizontal cell (HC) types (H1, H2, H3, and H4) and photoreceptors was studied in zebrafish retina. Since HCs are strongly coupled by gap junctions and feedback from HCs to photoreceptors

Recovery after crush of neuroendocrine caudodorsal cells (CDCs) in the aging brain of the mollusc Lymnaea stagnalis, was determined as a measure of neuronal plasticity. Neuronal plasticity was determined in differently aged animals containing intact

Metamorphic control of cyclic guanosine monophosphate expression in the nervous system of the tobacco hornworm,Manduca sexta

During metamorphosis of Manduca sexta, defined sets of neurons show a dramatic accumulation of cyclic guanosine monophosphate (cGMP). Although many of these cells show low but detectable levels of cGMP during specific developmental windows, these lev
