0:00:30 > 0:00:33# Be happy, be healthy and get well soon
0:00:33 > 0:00:36# Cos the doctor and nurse Well, they know what to do... #
0:00:36 > 0:00:37They do!

0:00:55 > 0:01:00# Get well soon. #
0:01:03 > 0:01:04Hello! I'm Dr Ranj.
0:01:04 > 0:01:08Welcome to our very special hospital just for children.
0:01:08 > 0:01:10Come on, I'll show you around.
0:01:17 > 0:01:21Lots of clever people like doctors and nurses work here,
0:01:21 > 0:01:26and they're specially trained to care for children, just like you.
0:01:29 > 0:01:33You may come here because you're not feeling well
0:01:33 > 0:01:35or you need to have a test
0:01:35 > 0:01:37or an operation.
0:01:39 > 0:01:41- Hello!- Hello, Dr Ranj.
0:01:43 > 0:01:46But don't worry, whatever you're here for,
0:01:46 > 0:01:50there'll be someone like me to check that you're healthy
0:01:50 > 0:01:52or to help you get well soon.
0:01:53 > 0:01:57This is my floor. I'd better get to work!
0:01:58 > 0:02:01Hello! We're in the neurology department.
0:02:01 > 0:02:04This is where we see people for anything to do with the brain.
0:02:04 > 0:02:09I have a patient coming to see me today. I wonder who it will be.
0:02:09 > 0:02:11Who's come to visit me? Who will it be?
0:02:11 > 0:02:15Can you guess which friend it is? Let's see.
0:02:18 > 0:02:20I know who that is!
0:02:20 > 0:02:22It's Riz!
0:02:22 > 0:02:25# The world's so full of what and why
0:02:25 > 0:02:28# I really have to know!
0:02:28 > 0:02:32# How does it work and what is this?
0:02:32 > 0:02:35# And where does that thing go?
0:02:35 > 0:02:38# So much to know
0:02:38 > 0:02:41# So much to learn and do
0:02:41 > 0:02:44# When I find out something new
0:02:44 > 0:02:48# I want to shout woohoo!
0:02:48 > 0:02:51# So much to know
0:02:51 > 0:02:54# So much to learn and do
0:02:54 > 0:02:57# When I find out something new
0:02:57 > 0:03:02# I want to shout woohoo! #
0:03:03 > 0:03:08- Hello, Riz! Come and sit down. - Hello, Dr Ranj. Phew!
0:03:08 > 0:03:11Did you ride your bike here today, Riz?
0:03:11 > 0:03:14- No.- So why are you wearing your helmet?
0:03:14 > 0:03:16In case I fall down, Dr Ranj.
0:03:16 > 0:03:19Oh, have you fallen down recently, Riz?
0:03:19 > 0:03:21Yes, but I don't remember much.
0:03:21 > 0:03:25One minute I was standing up and the next minute I fell on the floor.
0:03:25 > 0:03:28- Oh!- I'm sorry to hear that.
0:03:28 > 0:03:32- Do you remember how you felt before you fell down?- Hmm.
0:03:32 > 0:03:36I remember feeling a bit sick and dizzy, Dr Ranj, but that's all.
0:03:36 > 0:03:39It sounds like you may have fainted, Riz.
0:03:39 > 0:03:42I don't think I painted anything, Dr Ranj!
0:03:42 > 0:03:46- Fainted not painted!- What's that?
0:03:46 > 0:03:50Fainting is like your body suddenly going to sleep without telling you.
0:03:50 > 0:03:53Why did my body do that, Dr Ranj?
0:03:53 > 0:03:56You might have fainted for lots of different reasons,
0:03:56 > 0:04:00but it might be because of something that happened in your brain.
0:04:00 > 0:04:03What's my brain, Dr Ranj?
0:04:03 > 0:04:08Your brain is a very important part of your body inside there.
0:04:08 > 0:04:10Inside my head?
0:04:10 > 0:04:13But Granny said my head is made of wood.
0:04:13 > 0:04:15It's not made of wood, Riz! She's joking!
0:04:15 > 0:04:18You've definitely got a brain inside there.
0:04:18 > 0:04:20What does it look like, Dr Ranj?
0:04:20 > 0:04:23It looks a bit like this.
0:04:23 > 0:04:27It's all wrinkly. It looks like a big nut!
0:04:27 > 0:04:30And that makes my body do everything?
0:04:30 > 0:04:36Everything you do and everything you think is controlled by your brain.
0:04:36 > 0:04:39It's a bit like your body's very own computer.
0:04:39 > 0:04:42It doesn't look like a computer, Dr Ranj!
0:04:42 > 0:04:46But your brain does work a bit like a computer.
0:04:46 > 0:04:47How?
0:04:51 > 0:04:54Ooh!
0:04:54 > 0:04:57Your brain sends and receives millions of messages
0:04:57 > 0:04:59around your body all the time.
0:04:59 > 0:05:02Messages like, "Move your arm."
0:05:02 > 0:05:06Wow! My brain is really clever.
0:05:06 > 0:05:12But why did my brain tell me to faint and fall down, Dr Ranj?
0:05:12 > 0:05:15That's what we're going to try and find out today, Riz,
0:05:15 > 0:05:17by doing a special test.
0:05:17 > 0:05:20Ooh! A test! Will I have to do a puzzle, Dr Ranj?
0:05:20 > 0:05:24It's not that kind of test, Riz. You won't have to do any puzzles.
0:05:24 > 0:05:28Oh, Granny does crossword puzzles all the time.
0:05:28 > 0:05:30She says they're good for her brain.
0:05:30 > 0:05:33What test do I have to do, Dr Ranj?
0:05:33 > 0:05:38The test we are going to do today is called an electroencephalogram.
0:05:38 > 0:05:41An electro-what-o-gram?
0:05:41 > 0:05:43Electroencephalogram.
0:05:43 > 0:05:47It's a bit of a long word so we call it EEG for short.
0:05:47 > 0:05:51An EEG looks at the electricity inside your brain.
0:05:51 > 0:05:57Electricity in my brain? That sounds dangerous!
0:05:57 > 0:05:59Don't worry, Riz.
0:05:59 > 0:06:03The electricity in your brain is a special type of electricity.
0:06:03 > 0:06:05It's not like the electricity at home.
0:06:05 > 0:06:08But why is there electricity in my brain?
0:06:08 > 0:06:13- Your brain uses electricity to send its messages.- Oh!
0:06:13 > 0:06:17- Are you ready now? - I'm ready, Dr Ranj!- Good.
0:06:17 > 0:06:20First, I need you to take off that cycle helmet
0:06:20 > 0:06:23- and lie down on the couch.- Oh, yes.
0:06:27 > 0:06:28There we go.
0:06:28 > 0:06:32I'm going to need to put some sticky sensors on your scalp
0:06:32 > 0:06:33which I need to clean first.
0:06:33 > 0:06:37Are you going to cut my hair off, Dr Ranj?
0:06:37 > 0:06:39No, Riz, I don't need to cut your hair,
0:06:39 > 0:06:42but you might want to wash it when you get home.
0:06:42 > 0:06:46- These sticky sensors are quite sticky.- OK.
0:06:46 > 0:06:49What are those wires for, Dr Ranj?
0:06:49 > 0:06:54They sent the electrical signals to the EEG machine.
0:06:54 > 0:07:00The EEG machine shows us all the electrical activity in your brain
0:07:00 > 0:07:02in a pattern we can see on the screen.
0:07:02 > 0:07:04Why?
0:07:05 > 0:07:08We look at the pattern to check that the electricity
0:07:08 > 0:07:10in your brain is doing what it should do.
0:07:10 > 0:07:14But it just looks like a load of squiggles.
0:07:14 > 0:07:17The squiggles are made by the electricity in your brain.
0:07:17 > 0:07:19Brain squiggles!
0:07:19 > 0:07:23If one of those squiggles doesn't fit the right pattern,
0:07:23 > 0:07:26it might be that some of the messages from your brain
0:07:26 > 0:07:28aren't going where they should be.
0:07:28 > 0:07:31Can you see what I'm thinking?
0:07:31 > 0:07:33DR RANJ LAUGHS No, Riz!
0:07:33 > 0:07:36I can only see the electricity inside your brain.
0:07:36 > 0:07:38What do I have to do now, Dr Ranj?
0:07:38 > 0:07:41All you have to do is sit quietly for a while, Riz.
0:07:41 > 0:07:44Will I feel the electricity, Dr Ranj?
0:07:44 > 0:07:47Will it give me a shock? Buzzzz!
0:07:47 > 0:07:51No, Riz, you won't feel anything and you definitely won't get a shock.
0:07:51 > 0:07:53- Just relax.- OK.
0:07:53 > 0:07:56This is the easiest test in the world.
0:07:56 > 0:07:59All I have to do is sit still!
0:08:00 > 0:08:03# An EEG is amazing and it's just like I said
0:08:03 > 0:08:07# It watches all those neurons so busy in your head
0:08:07 > 0:08:11# So you can tell what's working well and if my brain is fine
0:08:11 > 0:08:14# I can see what's going on in every squiggly line
0:08:14 > 0:08:17- BOTH:- # Those wavy, wiggly lines
0:08:17 > 0:08:21# They can help the doctor tell
0:08:21 > 0:08:25# What's going on inside your head
0:08:25 > 0:08:28# And if your brain is working well
0:08:28 > 0:08:30# Your brain is so amazing
0:08:30 > 0:08:32# It makes you talk and play
0:08:32 > 0:08:35# Without your brain, you couldn't do anything today
0:08:35 > 0:08:39# Let's hear it for the neurons it's like the doctor said
0:08:39 > 0:08:42# Neurons in their billions, so busy in your head
0:08:42 > 0:08:46# Those wavy, wiggly lines
0:08:46 > 0:08:49# They can help the doctor tell
0:08:49 > 0:08:53# What's going on inside your head
0:08:53 > 0:08:57# And if your brain is working well
0:08:57 > 0:09:00# Wavy, wiggly lines
0:09:00 > 0:09:03# They can help the doctor tell
0:09:03 > 0:09:07# What's going on inside your head
0:09:07 > 0:09:11# And if your brain is working well. #
0:09:11 > 0:09:15OK, Riz, that's the end of the test. We're all finished.
0:09:15 > 0:09:18I nearly fell asleep, Dr Ranj.
0:09:18 > 0:09:22That's OK, Riz. You were keeping very still. Well done!
0:09:22 > 0:09:28I just need to remove the sensors from your head, and you can go home.
0:09:30 > 0:09:34- Did you see my brain squiggles, Dr Ranj?- I did, Riz.
0:09:34 > 0:09:35And it all looks OK.
0:09:35 > 0:09:40But we'll need to take a closer look at the results to double-check.
0:09:40 > 0:09:43When I've done that, you can come and see me again
0:09:43 > 0:09:46- and I'll show you the squiggles too. - Cool!
0:09:46 > 0:09:48In the meantime, I think you deserve a stickler
0:09:48 > 0:09:50for coming to see me today.
0:09:50 > 0:09:54And now you know what a clever job your brain does,
0:09:54 > 0:09:58you need to protect your head if you're going to ride your bike.
0:09:58 > 0:10:00I'm not going to ride my bike, Dr Ranj.
0:10:00 > 0:10:05I'm covering up my hair. You made a right mess of it!
0:10:05 > 0:10:09Sorry about that, Riz. Your hair will be fine after a wash.
0:10:09 > 0:10:13- I know. Thanks, Dr Ranj. - You're welcome. Bye, Riz.
0:10:13 > 0:10:15Bye!
0:10:17 > 0:10:21It's time for me and everyone at the children's hospital to say goodbye.
0:10:21 > 0:10:24Thanks for coming to see us. See you next time.
0:10:24 > 0:10:28But until then, be happy, be healthy and get well soon!
0:10:47 > 0:10:50If you're not feeling well, it's always best
0:10:50 > 0:10:53to go and see your own doctor and get well soon.
