Neurophysiologic Analysis Not surprisingly, in keeping with prior studies (e.g., 28 , 55 , 57 ), on average, there was a highly significant effect of odorant on both the spatial patterns of different odorants (F [4, 430] = 128.28; P < 0.00001) and the response magnitude (F [4, 437] = 117.26; P < 0.00001).
