Processing of spectral information in the dragonfly lamina

Yang, En-Cheng


In this thesis, intracellular recordings were made from the photoreceptors and large monopolar cells (LMCs) of the dragonfly, Hemicordulia tau, to study the spectral information processing in the early vision of the insect compound eye. Photoreceptors recorded from the ventral region of the compound eye could be divided into five groups (360 nm, 420 nm, 460 nm, 530 nm and 590 nm) according to their peak spectral sensitivities. Compared to the previous study by S. Laughlin in 1974, where only...[Show more]
