Amplitudes and latencies of fetal ERs for the short ITI condition. Fetal age (“Age”; in weeks of gestation), number of triggers (“Tri”) recorded, response amplitudes (“Ampl”; RMS values in fT) with each numbered flash, and latencies (“Lat”; in ms) with each numbered flash.

Visually selected responses that were over the threshold detection but proved non-significant after the bootstrap test.
