1.   This suggests that the visual mechanisms involved in discrimination performance change after visual cortex ablation.

2.   The other mechanism involves the effects of heating associated with plate subduction.

3.   And scientists are encouraged that they know the precise mechanism involved with Propecia, but not with Rogaine.

4.   For the first time, that is conceivable, because researchers finally understand the mechanisms involved.

5.   Kirschvink said one recovery mechanism might involve the pumping of heat-trapping carbon dioxide into the atmosphere by extensive volcanic eruptions.

6.   The second mechanism involves cells in the back of the retina known as rods and cones.

7.   This mechanism involves vitamin D.

8.   This mechanism involves a protein called dopamine, which activates nerve circuits in the most ancient area of the brain to generate a sense of pleasure or well-being.

9.   What was the common mechanism involved?
