Power spectral slope

1. Power spectral slope is associated with manual dexterity in humans.

   “Finally, the slope in the stroke group was associated with performance on a test of manual dexterity, but this association was stronger in older individuals, and varied by scalp region.”

1. Stroke is associated with power spectral slope in humans.

   “stroke was associated with a significant increase in spectral slope, but age moderated this effect. Younger stroke patients showed minimal difference in slope while older stroke patients had significantly steeper slopes”

1. Normal ageing is associated with power spectral slope in humans.

   “We found a significant flattening (decrease in exponent) of power spectral slope with normal ageing.”
