0:09:50 > 0:09:57.
0:10:04 > 0:10:07Welcome to Science Fiction, where you supply the questions.
0:10:07 > 0:10:10And we apply the science. Argh!
0:10:10 > 0:10:12What's today's question, BUD-E?
0:10:12 > 0:10:15Two ticks, Doc. Me old processor's gone a bit wonky, there.
0:10:15 > 0:10:18Today's question comes from Fiona in Athlone-a...
0:10:22 > 0:10:26Ah, this'll be a real test to the old grey matter, Fiona.
0:10:26 > 0:10:30The brain is composed of billions of tiny cells, called neurons,
0:10:30 > 0:10:33that communicate with each other via electrical signals.
0:10:33 > 0:10:36Kind of like loads of little gossipy grannies running around,
0:10:36 > 0:10:37nattering away inside your head.
0:10:37 > 0:10:40Now, these neurons control different functions
0:10:40 > 0:10:42depending on what part of the brain they're in.
0:10:42 > 0:10:45So, one area controls language and thought,
0:10:45 > 0:10:48another movement and balance, another breathing...
0:10:48 > 0:10:50Another, what peanut butter you like,
0:10:50 > 0:10:54- whether or not you can tickle a chicken...- Professor, please!
0:10:54 > 0:10:55Sorry, love, sorry.
0:10:55 > 0:10:58Oh, I'm feeling a bit light-headed after that.
0:10:58 > 0:11:01While all these parts of the brain may not be in use all the time,
0:11:01 > 0:11:04they are able to work together to allow you to do
0:11:04 > 0:11:06even the most complex of tasks.
0:11:09 > 0:11:10Ha!
0:11:10 > 0:11:13See, look what happens when I try to do this. Look.
0:11:16 > 0:11:20So, Fiona, the brain is a powerful and sophisticated machine
0:11:20 > 0:11:23and it's a total myth to say that we only use ten percent of it.
0:11:23 > 0:11:26So that's just a load of old science fiction, eh?
0:11:30 > 0:11:33I think I need to lie down after that. My head feels a bit funny.
