Brian Cox - Soviet Brain II lyrics

Some never get a chance to see a real human brain At least, not while its language cortex is holding a conversation with you And somehow remembering words, piecing them together into a sentence Picking and choosing which sentence to speak aloud, and which to leave in the subconscious to gestate a little longer To see the part of the brain that is causing the patient's epileptic seizures, the surgeon must remove a hand-sized piece of bone, opening up a window into the brain just above the line between left eye and left ear The bone must be taken out in one large chunk, because it will be reinstalled in the patient's skull late this afternoon to close that window Opening is a matter of drills and saws, and is consequently a little noisy The patient gets to sleep through that But it's over now, and the intravenous short-acting anesthetic has been stopped Allowing the patient to wake back up He needs to be alert during the next act And there is very little to cause pain at this stage in the operation Touching the brain's surface doesn't produce any sensations of touch The brain itself has no sensors for that sort of thing Although it receives messages from sensors elsewhere in the body We ought to be ready for the handheld stimulator in a few minutes
