Dedifferentation of motor cortex in healthy ageing
Using two lifespan fMRI datasets, we refuted the hypothesis that reduced motor
lateralisation in older adults compensates for age-related decline. Instead, results demonstrate
that this hyperactivation is non-specific, perhaps reflecting interhemispheric inhibition.

How the Human Brain Grasps Tools
A grasping fMRI experiment tested which brain regions represented actions
with 3D-printed kitchen tools, like a knife
(video example).
As covered by Nature,
the results mark an important step toward uncovering which brain regions evolved to
support tool-use,
a defining feature of our species.
