FRONTAL AND PARIETAL LOBE | EXPLAINED

Dr. Julie Brown, your Carrick trained and concussion doctor, board-certified chiropractic neurologist, and Fellow in Traumatic Brain Injury and Rehabilitation. I am going to continue down lobes of the brain, and what can happen when things go awry, or how they can present.
We'll start with the frontal lobe. So, the frontal lobe, since it is our personality, we can have changes in personality. We can not like being around people, people can not like being around us, we can get some of those personality disorders that psychiatrists work with, we can have changes in motor; so our movement patterns, how quickly we move, and memory. Memory is the other thing that we can have an issue with. That's our short-term, executive function, and that can be broken.
Also, when that frontal lobe's not working, we're more likely to react to a situation, rather than be able to calmly think and maybe not argue with a person.
Then we also have the parietal lobe, which deals with sensory. The sensory deals with light, touch, pain, temperature, and vibration. There are different pathways that lead up to the brain to let us know about that.
A good example, there are two good examples. One is going to be the Lego. You step on the Lego, it's going to be sharp, there's a pain fiber that comes up and says, "Hey, there's something sharp, we don't want to cut our foot." It will feed forward to the motor and say, "Hey, lift that leg, and also at the same time, try not to make us fall." These are reflexogenic circuits.
The other thing is you can have a sensory issue at the end organ, where it has a sensation, or you can have an issue in the nerve that goes up to the spinal cord, or you can have an issue with the spinal cord, therefore, we get changes in mapping in that parietal lobe. There are many areas for dysfunction, so when we talk about our diabetic patient that gets the ulcers, that is because the end organ neurons have been damaged and they cannot perceive sensation appropriately to say, "Hey, we're not getting blood flow. Lift your foot up and move." Instead, it just stays there and creates a sore.
That's it. That's all I have for parietal lobe. It's much more complex than that. I'd have to do an evaluation to tell you if yours are working, but if you'd like to know more, the website's below, or you can click on the link here to subscribe to me too.
