Sharper orientation tuning of the extraclassical suppressive-surround due to a neuron's location in the V1 orientation map emerges late in time

► Dynamics of extraclassical suppressive-surround tuning vary across V1 orientation map. ► Pinwheel cell tuning is broader and peaks earlier in time. ► Domain cell tuning is sharper, peaking significantly later in time. ► Slow tuning time course for domains suggests a role for slower cortical circuits. ► Long-range lateral input from like-oriented domains is a likely source.
