Hi Janet,
If you would like such a movie, I used MRIcro some time ago and I got
very nice results.
It is not an automatic way of obtaining the render (I wish there were
more automatic procedures in MRIcro because it is nearly perfect!!!) but
it's quite fast.
What I did was:
1. Overlay the activation on a structural image (in MRIcro)
2. Display the overlay in 3D (3D render)
3. Select the option Cutout
4. In 'Select a Region of brain cutout'
X from 1 to 182
Y from 1 to 217
Z from 181 to 181
This will display the whole brain. You can save a picture for your brain
with this cutout (if you want to see the results of the cutout, you
should close the cutout window after selecting the values).
5. Change sequentially the Z cutout (i.e. you can save the activation
picture with Z from 171 to 181, then another picture with a cutout from
161 to 181, then from 151 to 181, etc.) and save a picture every time
you change this value.
6. Make a video by means of any free utility, with all the pictures. I
used an easy tool called The RAD tools that went perfect for me
(http://www.radgametools.com/bnkdown.htm).
The results will be very simmilar to this:

Hope this helps!
