00:00uh look a letter dear tim and moby i was watching a nature show on tv about dolphins and they said

00:17that dolphins have bigger brains than humans is this true are dolphins smarter than people

00:21yours truly ethan p.s does moby have a brain yeah but it keeps it in the jar ethan it's true that

00:27some kinds of dolphins have larger brains than humans but that doesn't necessarily make them

00:31smarter scientists think that intelligence is more about the complexity of your brain than its size

00:36your brain is the most complex thing you own it's made up of billions of nerve cells that control

00:41everything in your body your brain controls all of your actions including the ones you don't have

00:45to think about like keeping your heart beating your brain is also what lets you think and remember

00:49all that work takes a lot of energy even though your brain weighs less than three pounds it uses up

00:54to twenty percent of the oxygen you breathe the brain is divided into three parts the forebrain

01:00the cerebellum and the brainstem the cerebrum the largest part of the forebrain is where you think

01:06it's divided into two halves called hemispheres some psychologists believe that in most people

01:11one hemisphere is dominant to say that someone is left-brained might mean that they excel at math

01:16and science and right brain people are supposedly better at art and writing the thalamus is also part

01:22of the forebrain it's like the brain switchboard passing information from your body to the correct

01:26part of the brain another part of the forebrain the hypothalamus controls your body temperature and

01:32food intake without the hypothalamus you'd keep eating and never feel full more

01:37the cerebellum coordinates your body's movements

01:41then there's the brain stem it monitors and controls all the little functions that keep you

01:48alive your heartbeat breathing blood pressure and whatnot i know moby it's a ton of information but

01:54the brain does a lot of work if you didn't have a brain you'd be dead oh right dolphins well now that

01:59we know a little more about the brain you can understand why it's hard to compare dolphin

02:02intelligence to human intelligence dolphin brains are bigger but the parts of their brains where

02:07conscious thinking occurs are very small so i don't think you'll be seeing dolphins in school with
