    Thank you so much for sharing this along with Phosphofructokinase II information. So far in reading biochemistry books, this is one of the most difficult concepts for me to get just from reading, and this really helps thank you.

    Thanks for your video. I, however, confused. It is claimed in the video that horizontal cell inhibits the centre photoreceptor. Then, why do we say that horizontal cells mediate lateral inhibition? I would be grateful if you could shed some light on this

    Considering the fact that the target is large and the retina cells are small I am pretty certain that this pseudointellectual explanation is the erroneous construct of some physiologist or group with a large ego and small mind giving their lab results too heavy a credence. Sorry , but I'm right.

    I have a question, how does photoreceptor decide whether it will be connected to a Bipolar ON or Bipolar OFF type, the video explains the working given either of the connection. Can a photoreceptor be connected to more that one Bipolar cell? Thanks

    So how does this get affected by pyrethrins? Like why would the channels be kept open? I was reading about shock dope lol I’m just curious as to what is happening in the brain that ordinary flowers can’t derive the same compound from, like how chrysanthemums can make pyrethrum for pesticides after undergoing a process

    To better understand this subject you need to go back to the research conducted by Hubel and Wiesel during the second half of the 20th Century. That was the foundation that lead to an understanding for the visual system. Their initial paper was published back around 1960 when I was in Jr. High School. I became interested in the subject in the mid to late 1960s and built an "artificial retina" using an IBM 1620 Computer a couple of years later.

    At minute 2:32 it said that on on bipolar cell it gets depolarize. But, should it be the opposite? Depolarize on off dipolar cell?

    Why does the number of sodium ions increase within the cell when the neuron is receiving an excitatory signal? Isn’t that a result of the gated channels opening?

    • @fzarza1534
      @fzarza1534 3 месяца назад

      It is from the chemical signals of the neuron that releases chemical signals before this neuron and which attach to the receptor proteins of this neuron. The attaching causes a signal for the gates to open and allow sodium ions in

    helo, i thought it was backwards? on depolarizes and OFF hyperpolarizes?

  • @enfissione8297
    @enfissione8297 Год назад

    Ignoring horizontal cells is bad. Plus i don't think they only release gaba to the center cones, they do it with all cones or rods?

    • @enfissione8297
      @enfissione8297 Год назад

      At least no paper i've read says that horizontal cells only inhibit cones in the center of their receptive field, so this model is incorrect according to what i know. But i can be wrong, not pretending to know it all or trying to be disrespectful
