      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.

      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.

    **The pupillary light reflex doesn't involve the LGB it goes directly to the olivary pretectal nucleus in the mid brain which then sends signals to the Edinger Westphal nucleus near the superior colliculus on both sides.
