The other is lateral interaction pathway, comprising local feedback circuits from horizontal cells
back to photoreceptors and from amacrine cells back to bipolar cells.
Researchers at the Scripps Research Institute in California, US, focused on amacrine and horizontal cells
in mice two types of neuron involved in the visual signalling pathway.
In the PNAS article, they demonstrated a nearly two-fold variation in the number of interneurons called horizontal cells
Although similar findings have been reported in turtle retina (4), studies of mouse retina suggest that murine horizontal cells
lack Cx26 (6), and express Cx57 (7).
THE ROLE OF GAMMA AMINO BUTYRIC ACID IN SYNAPTOGENESIS BETWEEN HORIZONTAL CELLS
AND PHOTORECEPTOR CELLS IN THE MAMMALIAN RETINA.
Grids were constructed in the 1-2-3 worksheet session by storing a string of keyboard symbols (such as =, -, or *) in consecutive horizontal cells
(rows) and a broken vertical line keyboard symbol in consecutive vertical cells (columns).
The team of neuroscientists shows that retinal horizontal cells
, which are nerve cells once thought only to talk to neighboring nerve cells and not even to the brain, are light sensitive themselves.
The present study was designed to determine the effects of zinc on hemichannels formed by Cx26, a connexin expressed on dendrites of carp horizontal cells
Histidine can also increase the membrane currents recorded postsynaptically from horizontal cells
during voltage-clamp in the skate retinal slice preparation (12).
are second order retinal neurons that receive direct input from photoreceptors and are involved in establishing a number of key features of visual perception.
Both the dose-response curve and the Hill coefficient are remarkably similar to results reported previously for hemichannel currents recorded from horizontal cells
isolated from skate (8) and catfish (9) retinas.
We have tested this hypothesis by the use of whole-cell, patch-clamp recordings from horizontal cells
in the skate retinal slice preparation.
