    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?

  • @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

    Do horizontal cells contribute the opposing signal of both the center cones and surround cones, or only of the surround cones? Additionally, when we are considering an off-center bipolar cell with an off-center and on-surround, we maximize the depolarization of the cell. However, since the horizontal cells contribute the opposing signal to that of the surround, is it reasonable to say that the off-bipolars are maximally excited because of both the higher rate of Glutamate from the off-cones to the off-center bipolars AND from the opposite signal of the more inhibitory surround cones (contributed to by the horizontal cells of the surround)? Your video states that there is lowered inhibition by the horizontal cells in this case, but can that be thought of as increasing the excitability of the center cones?
