Movement-related increase in contralateral central alpha-beta activity declined with age. Lower panel: Alpha-beta power changes at C3 electrode associated with each movement from 19 infants with best linear fit to the data (solid line, on a logarithmic scale). Top panel: Topographical heat map of the median change in alpha-beta power for younger (left: 31–35 weeks CGA) and older infants (right: 36–42 weeks CGA).
