摘要: Jumping spiders have four pairs of eyes (ocelli) which only the principal (PEs) are used to detect features objects. Photoreceptors in retina PEs form layers (PL1-4) and terminate first optic ganglion (FOG). Here, we focus on Hasarius adansoni because it has unique depth vision besides color its FOG appears contribute initial processing these visual modalities. We investigated neuroanatomical organization FOG. The three-dimensional structure revealed by synapsin immunostaining is horseshoe-shaped consists terminal zones (TZ1-4). Then, traced single photoreceptors through serial sections found that green-sensitive receptors PL1 2 TZ1 2, respectively, keeping retinotopic organization. In contrast TZ3 receives terminals ultraviolet-sensitive from lateral regions both PL3 4, while medial region 4 TZ4. further studied details photoreceptor branching pattern interneurons Golgi stained preparations. long processes each zone. Some terminating branches innervating TZ1, indicating different spectral information. A type interneuron connects others within a zone or entire These results suggest color, shape, vision, specific roles for UV vision.
