Key Concepts

Hypothalamus

The hypothalamus is a small but vital part of the brain that regulates a range of autonomic functions including sleep, hunger, and body temperature. It also contains centers involved in sleep regulation and helps maintain the body's internal clock, or circadian rhythms.

Cerebellum

The cerebellum, located at the back of the brain, is primarily responsible for fine-tuning motor activities and coordinating movements. It plays a crucial role in maintaining balance and in fine motor control tasks like hand-eye coordination.

Limbic System

The limbic system is a collection of structures that plays a key role in emotion, memory, and behavior. It includes components like the hippocampus and other related areas, which are involved in forming, processing, and retaining memories as well as mediating emotional responses.

Corpus Callosum

The corpus callosum is a thick band of nerve fibers that connects the left and right cerebral hemispheres, allowing for the transfer and integration of information between the two sides. Its function is essential for coordinating motor, sensory, and cognitive performances across the brain.

Cerebral Cortex

The cerebral cortex is the outermost layer of the brain, highly folded to maximize surface area, and it accounts for most of the brain's weight. It is responsible for many higher-order functions such as reasoning, perception, and voluntary motor activities.

0:00 All right.

00:01 So for this exercise, we are discussing the brain, specifically the different structures, and we're applying different concepts to blanks in order to demonstrate that not only are familiar with the concepts and the words, but how to apply them and what different contexts we can expect to see them.

00:15 So the first statement is if blank is severed, if blank is severed, then the right and left hemispheres cannot communicate.

00:31 The left and right cerebral hemispheres.

00:34 The cerebrum so i'll just write l and r cerebrum and i'll put a little red x indicating that they can't communicate so we're talking about the portion of the brain that connects the left and the right haphosphorus so the the portion of the brain that we're referring to is of course called the corpus callosum the corpus callosum which i will write in green here corpus callosum and if this is a meaning if the tissue is cut so that there is no longer a connection between the two.

01:15 Of course, they're still going to be next to each other, the hemispheres.

01:18 But if there's no clear connection between the two, if that's severed, your brain is not able to exchange information.

01:23 And this can actually be demonstrated with a variety of different neuroscientific or psychological tests, which is very fascinating.

01:30 I would highly recommend looking up aftermath of corvus colossum severance.

01:36 It's very interesting procedure and the outcomes it's fascinating to see how your brain actually communicates and the different rules left in the right hemispheres actually play with one another but that's more for another day we need to move on to part b where the blank and the hippocampus so a blank and the hippocampus and i'll abbreviate hippocampus as hippo are two components of the blank and we're just abbreviating again of the blank system that store memories all right system stores memories so here we have to be aware of different organs that are or different parts of the brain different right the brain is the organ different parts of the brain and how they might act in conjunction to perform us a similar task.

02:43 So the hippocampus is one of the parts.

02:45 So what is the other part that is actually the first blank? the first blank is actually the amygdala.

02:52 The amygdala? very fun to say word.

02:56 And it works alongside the hippocampus for the system that stores memories.

03:02 There's responsible for store memories, among many other things.

03:05 We would call this the limbic system.

03:07 And we typically think of limbic system as being more of a primal side of i guess human behavior and thoughts this is going to be a lot of more raw behavioral components such as aggression, sexuality, emotion, memory, things that aren't governed as much by logic that we would tend to think of but are more of our maybe animalistic tendencies caused by emotional component of being human, right? so that is the limbic system and those are two of the main players especially when we're talking about the memory storing components of the limbic system.

03:43 But let's move on to see.

03:45 So accounting for most of the weight of your brain, so most of the weight is, kind of for most of the weight of the brain is the highly folded.

04:03 So it's highly folded.

04:04 That's also worth noting.

04:05 I'll just put that in parentheses.

04:12 It's highly folded.

04:13 And take a little guess because the highly folded part really gives it away.

04:17 It's a cerebral cortex.

04:19 Talking with the cerebrum.

04:21 So cerebral means talking about the cerebrum.

04:21 So cerebral means talking about the abram, the large portion that sits above the brain stem and all that.

04:27 And the cortex is referring to the folds.

04:29 And interestingly enough, this is where it's believed a lot of our highly cognitive function is derived from, is derived from.

04:38 And this is the blank, by the way.

04:41 Because at first, it was just mostly stated that humans have large brains, which is true relative to a lot of other species.

04:47 But some species have much bigger brains than ours and our brains still much more higher functioning...
