蓝适应和橙子适应被用来分离视觉子系统对纹层反应的贡献。黑腹菌除了突出的开启瞬态和关闭响应外，细胞外板层响应还包含来自小网膜细胞R7和R8的衰减组分。在薄层范围内测量的闪烁融合频率与在受体区域测量的频率是无法区分的。由受体细胞R1-R6介导的反应以比R7和R8反应高3倍的频率融合。
Blue adaptation and orange adaptation are used to isolate the contributions of the visual subsystems to the lamina response of D. melanogaster. Besides the prominent on-transient and off-response, the extracellular lamina response also contains an attenuated component from retinula cells R7 and R8. Flicker fusion frequencies measured in the lamina range are indistinguishable from those measured in the receptor region. The response mediated by receptor cells R1-R6 fuses at a 3-fold higher frequency than the R7 and R8 response.
