What the heck is a magnocellular neuron you say? Douglas W. Stephey, O.D., M.S. will tell us why is it important to attention, movement, reading, and understanding where we are in space. Furthermore, the magnocellular visual pathway also plays a role in staying out of being in a perpetual state of fight or flight. This visual pathway will be explained in easy to understand detail and will be differentiated from the parvocellular or what visual pathway. Douglas W.

Dr. Stephey: If our two eyes are not working together well as a fast synchronized team, our internal mapquest continues to be off. It's consistently inconsistent with our ability to judge time and space. Those that don't feel well-grounded, those that have some measure of anxiety, oftentimes it starts in the visual system. If you can't move, look and listen in a fast, accurate, effortless, sustainable, age appropriate, meaningful way, you're in a world of hurt. There's a whole world in vision and how it affects brain function that no one's ever shared with you. 20/20 is perceived as a holy grail of going to the eye doctor. Well, I'm here to change that paradigm. Tim Edwards: This is the Move Look & Listen podcast with Dr. Doug Stephey. I'm Tim Edwards, the founder of the Inbound Podcasting Network, and a patient of Dr. Doug Stephey. He located in Covina, California. Episode four today, Dr. Stephey. We're talking about seeing fast. Never heard that phrase ever. And I've said that a lot in the last few episodes. I've never heard that before. Going to visit various optometrists throughout the last 25 years or so when I first started wearing glasses. It seems like everything that you bring up, every time we get together, there's something new and enlightening regarding our vision and our brain and how our eyes work together. Seeing fast. Tell us what that means. Dr. Stephey: Yeah. What the heck? Seeing fast. What's that all about? Well, certainly come into the optometrist. 20/20 is perceived as the holy grail of going to the eye doctor, right? If you could walk out seeing 20/20, it's all good. Dr. Stephey: Well, I'm here to change that paradigm. Fundamentally, the world generally is made up of prey, animals and predators. And prey animals have eyes on either side of their head, like horses and rabbits and predators have eyes closely spaced on their face. Tim Edwards: Like us. Dr. Stephey: Like us. And the reason that's true when you really stop and think about it. Is prey animals have to have almost a 360 degree field of view because they want to know when a predator is coming to eat them and they need to be able to see fast themselves in order to give them enough time.. Dr. Stephey: To flee the scene. Right? Because prey animals generally don't have great fighting skills. Their abilities to survive another day is that they have camouflage and they're fast, short term sprinters, and then there's lack of movement. Like the proverbial deer in headlights. Tim Edwards: So they can either hide or escape quickly. Dr. Stephey: That's it. Tim Edwards: To survive. Dr. Stephey: So predators have eyes closely spaced on our face because we need to be able to see in 3D. Now inherently to that we have to use our two eyes together as a well integrated team. And we also have to be able to see fast. And we have to see a large volume of space. Because if you and I were out walking down a wooded trail and we're looking at something straight ahead of us at 12:00 and the deer that hurt us, or saw us coming was off at 10:00 and it's now holding still because it doesn't want to enter our visual radar. So you and I are looking at 12:00.. Dr. Stephey: There's a movement in our periphery. If we're able to see fast, one, we should be able to perceive the movement and two, we should be able to localize a general area space of where that movement is coming from. So that when we turn and look and use eye focusing, eye tracking, eye taming skills to localize where we think we perceive that movement well then we should kick in our pattern detecting abilities so we can break ...
