oooh so puny. let's be real. this is just to help me study. so unless you're interested in neuroscience or just want to see how much I'm going to tell you....you really don't need to feel like you have to read this. although there's some good stuff in here.
let me tell you the parts of the nervous system. we've got the CNS and the PNS. The PNS is made up of the autonomic [internal] and somatic [external] systems, which break further into afferent [advance, arrive] and efferent [exit, escape]. Then off of the efferent part of the autonomic we have the sympathetic and parasympathetic systems. the sympathetic system deals with arousal. the parasympathetic deals with relaxation.
The CNS gets crazy. Ready? It's the spinal cord and the brain. The brain has 5 divisions: telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon. All of those minus the tele one are part of the brain stem. The telencephalon is the most complex. It's made up of the hippocampus, cerebral cortex, basal ganglia, and limbic system [Harry Can't Be Lumos]. The basal ganglia is made up of caudate, putamen, amygdala, globus pallidus [Cedric Plays A Game]. The limbic system is as follows: hippocampus, septum, fornix, amygdala, mammillary bodies, cingulate cortex.[Hagrid Sees Fluffy At My Castle].
On to other stuff. How about the 6 things that make up Neo-Darwinism? Okay! Even Lily Has Called Severus Great. 1. Environment 2. Life 3. Heredity 4. Continuity 5. Sex 6. Genetics
Now the 6 Methods of Brain Damage? 1. Tumors- can be infiltrating or encapsulating, malignant or benign, or metastatic. 2. Cardiovascular diseases- these are like strokes, ischemic thrombosis, arterosclerosis, etc.. 3. Closed Head injuries- concussions! When you get a bunch of concussions that are all fairly little over time that's called punch drunk syndrome 4. Brain Infections- bacterial or viral 5. Neurotoxins- mecury, lead 6. Genetic Factors-PKU, Downs
Then there's epilepsy and the different types of seizures. We've got 1. Generalized- gran mal vs petit mal. When you think of what a seizure is you probably think of the whole shaking and the tongue etc...that's gran mal. Petit mal is an absence seizure. 2. Partial- simple or complex. Simple have motor and sensory symptoms, complex have psychological symptoms.
Onto some more diseases! Parkinson's, Huntington's, Alzheimer's.
1. Parkinson's- movement disorder, I think this is the one that's like a lizard? Don't ask. I don't know where that came from.
2. Huntington's- this is genetic. If you've got the gene, it's unavoidable and terminal. If your mom or dad has the gene there's a 50% chance you'll get it too. This is also motor related, then intellectual as it progresses.
3. Alzheimer's- dementia is the main thing that categorizes it. only able to definitely diagnosis with an autopsy bc of the neurofibullary tangles and these other things umm amyloid plaques. Lovely.
I think that's all I've got for ya now. Do you know your memory? Betcha don't as well as I do! You've got to encode before you can consolidate and then you have to retrieve. Consolidation is how you make memory and it doesn't happen right away. It's like an ice cube tray. It takes a while for that water to turn to ice. If you shake it before it's done...oh no. Alcohol, closed head injuries and ECT can all mess up consolidation. H.M is the most famous case that has brought us so much knowledge on memory. He had a bilateral medial temporal lobectomy. meaning that that part was completely cut out of his brain. not like a lobotomy which just cut but not removed. He had really bad seizures but then after the surgery he was much better! Except his memory suffered. He had AWFUL anterograde memory. meaning forming new memory didn't really happen. explicitly at least. Based on some tests like the mirror something or other and the .....AHHHH I DON'T EVEN CARE ANYMORE. DAVID CROWDER'S LAST ALBUM IS AVAILABLE FOR PREORDER ON AMAZON. BEST DISCOVERY TODAY. THANK GOODNESS I'M ALONE IN THIS STUDY ROOM SO I COULD FREAK OUT AND NOT EMBARRASS MYSELF!
finals...psh. i know what i'm listening to when i'm flying to scotland. it comes out the day i leave. heck yes. good thing i don't leave till the evening that day either so i'll for sure get it before i leave. or i better. that'd really suck if i didn't. which is why i might see if my awesome friend heather, who is going to PASSION 2012 will buy me a copy of the cd there because it'll be available to all attendees. jealous. David Crowder is my favorite person ever. and he doesn't even realize it. He's why I came to Baylor. What? yeah. if you didn't already know that, now you do. i don't share that because people don't understand. obviously.
