main organ of the nervous system and it's found in all vertebrate and most [multiple choice and brain photo]
invertebrate animals and congressmen. Humans differ from most mammals, because
we have a much more developed cerebral cortex. This allows for better planning,
reasoning and abstract thought. Basically the reason we have zoos. So is
homeostasis controlled by B, the thalamus? Well the thalamus is involved in sensory
and motor signal relay, as well as the regulation of consciousness and sleep.
This is pretty important stuff, but it isn't what we're looking for in the [romans in coliseum]
question. Let's cross off B from our potential answers there. How about C,
the amygdala. The amygdala is an almond-shaped mass of cells, that is
involved in many of our emotions and motivations. It also determines what
memories are stored in your brain. So again pretty cool, but not what we are after. So
cross off C. But would it be D, the hippopotamus, a hippocampus, sorry.
The hippocampus, which is not a university for a certain African animal, actually
plays a major role in long-term memory and spatial navigation. Not regulating [two hippopotamuses]
homeostasis, so ditch D. Perhaps it E, the fornix. Well the fornix, despite
sounding like an underground punk rock band, is actually a bundle of nerves that
carry signals from the hippocampus to other parts of the brain. If we cross E
off our list then we're just left with yeah A, the hypothalamus. The hypothalamus
controls homeostasis in part, by controlling the metabolic rate. Basically
it tells you when to eat, when to stop eating and other stuff. Oddly enough our
hypothalamus seems to shut down whenever we eat sour patch kids. Like well
that might be just us. So the correct answer is A, hypothalamus. Well we've
learned about quite a few parts of the brain, in this lesson. Maybe next week [picture of a brain]
we'll discover the part, that keeps getting Katy Perry songs stuck
our head. Baby you're a firework. We didn't say we could sing. Gluten-free brains.
