I have watched many KZbins 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.

[@andreahuicochea1300]

Best lesson ever! Thank u very much!

[@kelemicheal6897]

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 KZbin en el canal..

[@aishazel]

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? 😰

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

Amazing video, no mention of nerve lesions affecting miosis and mydriasis? Drugs, horners syndrome etc?

[@nwabisa2196]

Thank you so much for your videos

[@dr.anmolgodara5766]

Very helpful. 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

[@hamszeyad321]

thank you for your effort

[@masteredautononomus_fighter]

This is so cool how the optic nerve react

[@j.sbhandari8813]

[@lola-b5y]

Thank you... You are amazing 💗

[@iakpro2848]

What makes the nervous system "decide" wherever to go for the dilation of pupil or constriction of the pupil? What is the dynamics inbetween the sympathetic/paras pathways' activation/deactivation in respect to pupillary light reflex and eye accomodation? Thanx

[@shilpasenta6826]

[@Updula]
