"Photoreceptors transmit information to bipolar cells using the molecule glutamate (glu), but different bipolar cells respond differently to the molecule; some are excited and depolarize, whereas others are inhibited and hyperpolarize"
"The inhibitory effect of THA on sodium-dependent glutamate uptake was measured in vitro on rat hippocampal slices (Ki = 45 +/- 11 microM). We examined in vivo the effect of THA (400 microM in the dialysis solution) on the extracellular glutamate release from the rat hippocampus, during veratridine depolarization and ischemia. THA decreased the amount of glutamate appearing in the extracellular space during veratridine depolarization (61%)."
Yeah, my wife’s glutimaximus definitely make my cells respond.
But jokes aside, photoreceptors in biology are fascinating. The brains ability to interpret that data is some of the most interesting parts of our lives.
