Expression of Man1a. Man1a expresses densely in the cortex, making it difficult to visualize expression deeper inside the brain. The view with no filtering is shown in (a). Low density and low level expression is hidden in (b) to emphasize the striatum and hippocampus – the lower right hand corner shows the thresholding control. In (c), a coronal clipping plane is used to hide expression from roughly the striatum forward. A coronal atlas section is shown behind the striatum to hide expression towards the back of the brain. The combination of clipping plane and atlas section reveals expression restricted to a layer of the cortex. A similar result can be achieved by setting both front and back clipping planes and showing the outer surface of the cortex (d).
