One thing the video missed out is that the neurotransmitter used from the presynaptic membrane of the cones to the postsynaptic membrane of the bipolar cells is GABA. GABA is an inhibitory neurotransmitter, hence the less of it being produced the more the bipolar cell will be activated. So when a cone receives light and hyperpolarises (as mentioned in the video) it will decrease the amount of GABA released (as the cone cell cannot propagate the signal to the presynaptic membrane) and hence the bipolar cell will be less inhibited and will fire more. The opposite is true for when there is no light input, the cone cell will be depolarised so an action potential can propagate meaning more GABA will be released by the cell and so more inhibition will occur on the postsynaptic bipolar cell.

not true, glutamate is always released. On centre has mGlur6 and off centre has Ampa or Kainate
@mattaku9430 Жыл бұрын
Yeah, that Hc behaviour description is really weird. When cells are depolarises HC releases GABA, which in turn inhibits CaV channels preventing Ca2 from flowing in, so that PR achieves resting state. When cell is hyperpolarised it’s releases less GABA, which in turn disinhibits CaV channel, so those black surrounding will depolarise. It’s a self stabilising loop with negative and positive feedback

Fantastic explanation about the concept of the receptive field of the RGC - I'd just want to add something in case some people had the same question as I did whilst watching this video: Both photoreceptor cells of the retina (Rods and Cones) utilise ONLY glutamate as a neurotransmitter - which evokes the question: How is it possible that an ON CENTER bipolar cell even exists, because glutamate is EXCITATORY and somehow the ON CENTER bipolar cell reverses the sign of the ON CENTER cone cell, so how such an arrangement possible? So apparently it is because in the retina we have a special type of glutamate receptor which is actually INHIBITORY, and the ON CENTER bipolar cells have these kind of inhibitory glutamate receptors on their synapses - therefore when the ON CENTER cone cell is going to release glutamate on the ON CENTER bipolar cell it is actually going to be an INHIBITORY "message", NOT an excitatory message, which totally goes against the conventional "glutamate is an excitatory neurotransmitter idea" - apparently for this type of arrangement in the retina glutamate can actually act as an inhibitory neurotransmitter because of these specialized INHIBITORY glutamate receptors.

Yes, a little background in one of the teams that was heavily involved in recognizing metabotropic g protein coupled receptor on the synaptic cleft of the teledendron of the peripheral process of the bipolar cell, this GLUM6R in the prescene of GLU will activate the g protein which as of this time it is unknown the cascade effect that eventually ends up blocking the same receptor and preventing cations from flowing into the cell, when there is low amounts of GLU (when the photoreceptor is hyperpolarized) the G protein won't be stimulated and so the receptor will open and allow depolarization to occur (although it's technically not depolarization beacuse all retina cells except Müller and Ganglion cells are so small, photoreceptors 2-3 mircons in diameter, that there is no need for action potentials, only changes in electrotonic voltage will be sufficient to exocytose the neurotransmitters on their respective teledendrons) thus effectively creating a sign reversing synapse

Sir is there any answer for what is time and how it induces life to evolve even an organism to get older, I have an answer but it needs a thorough explanation via research wait for few years I will provide it i.e. The theory of everything.
