:49:16
	It's a symptom...
:49:21
	...of a type of disturbance in
the chemical-electrical activity of the brain.
:49:25
	In your daughter's case,
in the temporal lobe.
:49:27
	Up here in the lateral part of the brain.
:49:30
	It's rare, but it does cause
bizarre hallucinations...
:49:33
	...and usually just before a convulsion.
:49:35
	A convulsion?
:49:36
	The shaking of the bed.
That's doubtless due to muscular spasms.
:49:41
	No, no, that was no spasm.
:49:44
	I got on the bed.
:49:45
	The whole bed was thumping
and rising off the floor...
:49:49
	...and shaking, the whole thing!
With me on it!
:49:52
	Mrs. MacNeil, the problem
with your daughter is not her bed.
:49:55
	It's her brain.
:50:05
	What causes this?
:50:07
	Lesion in the temporal lobe.
:50:09
	It's a kind of seizure disorder.
:50:11
	Look, Doc, I really don't understand
how her whole personality could change.
:50:15
	In temporal lobe, it's very common.
:50:17
	It is?
:50:19
	It can last for days, even weeks.
:50:22
	It isn't rare to find destructive...
:50:25
	...even criminal behavior.
:50:28
	Hey, do me a favor, will you?
Tell me something good.
:50:32
	Don't be alarmed. If it's a lesion,
in a way, she's fortunate.
:50:36
	All we have to do is remove the scar.
:50:54
	Regan, can you sit up and scoot over here?
