Today we are exploring the history of neuroscience. I introduce you to a few neuroscientists whose work has shaped how we look at the brain and we talk about how their work has led to the way we are talking about neuroscience today. Enjoy the show.

Hello, everyone, it’s Dr. Sam, I’d like to welcome you to my EyeClarity podcast. This is a show that offers cutting-edge information on how to improve your vision and overall wellness through holistic methods. I so appreciate you spending part of your day with me. If you have questions, you can send them to hello@drsamberene.com. Now to the latest EyeClarity episode.
Alright, another neuroscientist I need to bring into the conversation. There are two of them today I want to bring in. And it’s a gentleman called Charles Sherrington, he came up with something called the Sherrington model. It’s a model that’s still used today, quite, it’s quite prevalent in the rehabilitation, the conventional rehabilitation movement system. And he’s the guy who developed something called the knee jerk reflex, he worked with the reflex model of the nervous system. And he also researched how spinal reflexes affect the muscles, and how that gives information to the nerves. And there’s a feedback loop that sees a feedback loop where the sensory information goes to the spine, and it goes to the muscles, and it creates this muscle tone posture relationship.
Now, one of the things about the Sherrington model that I find to be limiting is that it’s a bit linear, you know, and in the rehabilitation model, when I was working in the physical therapy, areas of the TBI in hospitals, I stepped out of the Sherrington model, because I found the sherry thing, Mark Sherrington model to be very much in the area of repetitive and superficial. And it didn’t really add the inquiry, the internal awareness that I found was needed, and being able to access a deeper level of neuroplasticity. So the sharing to model stays on the surface. And although it’s an important part of the history of nervous system development, I found that it really gave a limited view. And especially in eye care, nobody is talking about rehabilitation or regeneration, or neuroplasticity. But if we take it to the brain level, the nervous system, body level, there are so many dimensions to what we can do beyond the Sherrington model. This brings me to the next person that I want to introduce today.
And his name is Steven Porges. And he developed something called the polyvagal theory. And it’s a very involved idea of the evolution of the autonomic nervous system. But and I’m not doing full service to Dr. Porges. Because it’s a very complex theory. But one aspect that I want to spotlight today is this idea in our nervous system, we go through something called the fight, flight freeze response. And that’s kind of more of our reptilian reaction. We’re hardwired in that. But as we begin to soften the trauma events and the trauma imprints in our nervous system, we actually move to a more mammalian response, which is empathic capabilities. And social engagement is one of the keys to stimulating this type of evolution. So I’ll speak more about the polyvagal theory. On the November 13. Class, I’m also going to send you a handout.
That was a really fabulous interview, somebody interviewed Dr. Porges. But I want to say that the polyvagal theory is, in some ways, very connected to what we’re going to do today because it really can help us access a deeper level of neuroplasticity. And I don’t want to go too deeply into all the different aspects of the polyvagal theory because it can get kind of dense, and I want to stay focused on the practical aspects of what we need to do so that you can get what you need. So I’ll send you again this interview. I’ll talk more about it in our next lecture. You certainly can go to YouTube and type in Dr. Porges. He’s got some great YouTube videos. He’s also written a lot of different things.

He’s done a lot of research his wife, Dr. Sue Carter, has also done a lot of research in the area of something called oxy Tosun and vasopressin and how those impact our nervous system and fluid body. He’s worked very closely with one of my teachers, Emily Conrad Emily started the somatic practice continuum movement, you could certainly Google Emily Conrad and continue a movement. And she worked with Steven Porges. In the evolution of moving the continuum movement work further. So there’s a lot of connections here between Porges and Conrad. And those are some sources that you can look for in terms of your Google search.
