interesting the forebrain is highest integration sanitary elves nervous system and it's the seat of our consciousness so this that's stuff in a forehead right here for the cerebrum consists of two hemispheres so you got the two hemisphere one is here and one is up here and in between we have this long thing going down the deep in the brain it's a hole deep crevice right here you see that again oh look at that you see that right here goes deep down right to here where we have those commish world fibers at the corpus callosum and that's known as the longitudinal vision so aphasia is a deep deep groove we basically have that big one there and a few in the back of that or one or more in the back of the head the two hemispheres in the brain or January mirror bilaterally but they're dominated with different cognitive functions that is called we call it lateralization but we have to be careful so we don't want to do too many broad labels like left logic or right creative brain tendencies because you know too many generalizations we don't want to use that stuff as excuses however balancing them and have an enrichment to life I think is very important to focus on but that I think has more to do with balance of relaxation and cognitive doing versus you know on physical doing versus focusing too much on left and right brain logic stuff another interesting thing is that the part most that most most of the brain's impulses going down into the body but also coming back up they actually cross over so then cross the brain before they reach the body or from the body before they reach the brain the brain surface areas greatly enlarged by these convolutions here see these little wigglies this is actually what we see you this is what we see you and me look at the brain or these wiggle things there we go the wiggles here and then we got these little valleys and the valleys are known as salt kind to lateral so can the central sulcus central sulcus is right here on top and the laterals were right here this okay they divides the brain into five lobes because on the frontier this is the front we got a frontal lobe then you got two parietal lobes on the side in the back we got an oximeter low behind the ear we got the temporal lobe and then if we track that down inside we have an autologous known as the in Seward insular Oh generally speaking the frontal lobe deals with motor commands conscious thinking stuff working memory and judgment as well as problem-solving so that's really about that consciousness the precentral gyrus look at the precentral gyrus is in front of the central sulcus so that's that's here is the central sulcus right here in a glass tan or whatever the thing is supposed to be and then right in front of that here is the pre central gyrus the first twinkle right in front of it and that's where we have two primary motor cortex and the primary motor cortex is responsible for executing voluntary movements so these here see this here this is the Huichol this is the precentral gyrus and on here we actually see these body parts that when we they're actually laid out what they can they're not made out really but we visualize them on to because when we actually stimulate those areas with a little knife something when they do that in surgery neurosurgery they use plastic knife instead soft all that stuff but they then have this part that's described here is moved goes to those muscles in that area and then that body part moves so that's kind of neat and then this is a claymation thing where we see the body parts are sized to space occupied on the gyrus which indicates how many nerves concentration we have so look at here look at the the back is hardly any space and comparisons to the face or the tongue and so we see how many more fine motor skills we have in those areas that have a large amount of large amount of do runs a large growing concentration associated with them so that's me very neat little thing Broca's areas right here Broca's areas helps us make speech not Veronica's area those are two very specific places that Wernicke's area help us understand the written in the spoken language and the Verna Keys area is actually on the next slope and the next lobe is the parietal over that helps us experience the world through physical sensations such as touch temperature and pain it's very experienced consciously and processed the meaning of the received stimuli so all the stuff you think it's touching me or whatever that goes to that lobe see here primary somatosensory cortex is here that is now on the wiggle right behind the central sulcus that's known as the post central gyrus lots of words on the gyrus refers to the wiggle the cortex the word cortex refers to what's happening in there so in there is the somatic sensory cortex of that soma means body sensory means input that's the stuff like touch temperature pain that sort of stuff highway and this is an order claymation right here that shows us the of nerves of concentration in the sensory system I think this is kind of cool this is where we feel the world but you know then I feel like I'm a little nerdy about this stuff the parietal lobe also houses - ghost Ettore calm I mean the cortex and that encodes taste goes to Tori oops Casta Tori is taste and then we also have in the back here we have two occipital lobe and the occipital has the visual cortex in it I'll just do a few of those and then the primary had the temple of has the primary auditory cortex in it also that's going to be known as the acoustic central cortex or COO stick in the auditory interchangeable all right and then what's interesting here is also the weights this whole thing is organized so look at this picture down here we have this area like they're called primary areas and those are areas where we have beginning or termination of projection pathways so we have the primary area here that's that primary somatic or tax and then behind it we have that primary somatosensory cortex in green here and an association area surround the primary area and those are areas that the primary cortex and those are areas that influence so they think about I think of like that's what we think about what we're gonna do what we're gonna do and then oh we gotta go move and turn on the light so we have to then send stimuli to these different muscles same is true for the sensor is just the primary sensory cortex is where the information starts comes in and then it goes for processing to the Association areas and then you figure out would do about the stimuli came in it is like what's that a nice torture was that a slap in the face that kind of stuff you know then we go to the insula the insula is deep inside so it has the insula is right here insular lobe so we take we take the temporal away and deep inside we can feel sit in so I see like here you go have to go deep inside right here and then that's the insula lo path right there and that houses the vestibular cortex in testicular cortex concerns ourselves with conscious awareness of balance and I like this picture that Nina see when we look at here inside the visible cortex right in here more or less we have balance come from the equilibrium we also have balance coming from the eye as well and then you have more balance coming in from actually a lot of a lot of proprioceptors inside the muscles of the neck or also inside inside the joints of the neck and then the basal ganglia is where we go next and those are deep nuclei that regulate the extent and direction of voluntary movements especially when we start to stop we start moving when we stopped moving all that it goes about the intensity of movement automated movement movement patterns are stored here so that's like that piano or that guitar piece that you also remember how to play or it's not it's not that hard you don't have to think about it that much anymore that's when you know the stuff is stored in here it's also true for the fact that at this point you can just drive in a car much more coordinated than when you first learn to drive this part of the brain is referred to when we say practice makes perfect of course it really does mean practice makes permanent because whatever we learn does not the basal ganglia does not discern it it's perfect or not perfect it just makes it more permanent so it's good to practice with good form of course sister learning from that right then we get to the next interesting connection here in lower animals which means a love evolutionary old animals like salamander type stuff the cerebral cortex this is small and mainly pro is very small mainly processes olfactory stimuli and that smell and in us even the olfactory cortex is still very very important it's lined in an area where we have this thing called the Opus 2 uncle you know Uncas is the primary olfactory cortex and that's where we consciously figure out different odors awareness and you know get that stuff but what's really interesting is that that connects traits to our emotional brain which is called the limbic system see this word limbic system and that evaluates experiences based on feelings which is the word is affective effect is feelings and it triggers emotional reactions see all that yellow stuff that's all limbic system right there all right there so let's go through a few structures that are interesting in the limbic system the one that I think is crucially interesting is the amygdala look at that named amygdala here Oh Dola that's right that red sucker right there in the center of that head thing behind it you and that's in the temporal lobe temporal lobe that receives olfactory inputs also formal pheromones which are these body smell is that we send off that are making us attracted to one another Noah and that's where we process those you know or factory stimuli and then it also helps with memory creation but what's really interesting which is very often what takes over is the fact that recognition of angry or fearful facial expressions is also happening there so then we react to that so we have a danger assessment in there and a fear response so all that exact happens in the amygdala and so this is basically what that means is this is where we lose it there's where we have our temper or we have our amygdala hijack the term coined by David Daniel Goleman and that's a strong emotional reaction with a rapid onset and later go like what the heck was I thinking or somebody else tells you that which is actually in Reverse and embarrass you're very often but that's an interesting area and so we want to understand that area a little bit better the other thing that happens with the amygdala it sends to stimulate to the hypothalamus and that then involves the autonomic nervous system as well as the endocrine system so that's also very interesting when we then talked about psychosomatic Corrections body body mind connection things
