Size selectivity of LGN neurons over the course of development. A, Fraction of units responsive (rate, >2 spikes/s) to flashing spots and drifting grating stimuli. B, C, Average size tuning curve across the population at P14–P16 (B) and in adulthood (C). D, Average preferred spot size over the course of development. E, Average size suppression (calculated as fractional decrease in response to full-field flash vs preferred size) over the course of development. F, Average peak spatial frequency as measured with full-field drifting gratings. G, Average orientation and direction selectivity, based on circular variance, as measured with full-field drifting gratings.
