      I have watched many UA-cams and yours is my very first post. I thought it was outstanding. First, I am ADHD so it really helps to repeat words and ideas three times over. Also, I am usually driving and can’t see the board so it helps immensely to repeat and give my mind enough time to create a visual image. You tone is emphatic and you possess vitality which makes to sustain focus.
      Thank you very much!!!!yvette

    Small detail: I've read from several sources that the fibres for the pupillary light reflex bypass the LGN and project directly to the pretectal nucleus.

    Great presentation! Pupillomotor fibres leaves the optic tract before reaching the LGB (8.50 min). This explains the tectal RAPD.

      Contacta con la Doctora Ani John para cualquier tipo de problema de salud. Es un gran médico herbolario. Me curé del virus de la culebrilla justo después de 14 días. Estoy agradecida y no puedo dejar de agradecer al Doctor su amabilidad y buen corazón. Siempre diciéndome que estaré bien. Muchas gracias ❤️❤️. También puedes curarte a ti mismo con estas mismas hierbas. Siéntase libre de visitar Dr.Ani John en UA-cam en el canal..

    Actually pupillary fibres doesn't reach the upto LGB... Before LGB they exit half way in optic tract and reach Pretectal nucleus.

  • @toopidipoo1153
    @toopidipoo1153 5 років тому +4

    thank you very much! I really love your videos!!!! I was wondering.... Maybe I have not completely understood the pathway, but in class we learned that the fibers that go to the superior colliculus and pretectal nucleus come directly from the optic nerve but not from the lateral geniculus. Can this be clarified please? I am confused because in the drawing it seems that the superior colliculus and pretectal nucleus receive fibers from the lateral geniculate. Thank you so much for your videos, they help a lot!

    • @FranklinCavalHolme
      @FranklinCavalHolme 4 роки тому

      Good point. The melanopsin retinal ganglion cells that provide input to the pretectal nucleus synapse directly with the neurons in the pretectal nucleus (without making intermediate synapses with the neurons in the lateral geniculate nucleus). This is unusual since most retinal ganglion cells do synapse in the lateral geniculate.

    But I think when you talked about ciliaris action on lens.
    Shifting of lens of is lens importance.
    More important is change in curvature of lens which leads to change in refractory power of lens

    Then from the retina to the pretectal nuclei, there is ipsilateral distribution and from the pretectal nuclei to the edinger Westphal nuclei there is bilateral distribution and finally from the edinger Westphal nuclei, there is once again ipsilateral distribution to both eyes, Did I get it right? 😰
