Figure 2.

Components of the CS pathway involved in visually mediated ciliary locomotion in Hermissenda. Only connections with a single photoreceptor are shown. The diagram shows a monosynaptic connection between a lateral B-photoreceptor and type I_e and I_i interneurons. The dashed lines between the type I_e and I_i and type III_i interneurons indicate a polysynaptic pathway with unidentified interneurons. The monosynaptic connections between type III_i interneurons and VP1 have been previously established (Crow and Tian 2003). Filled triangles denoted inhibitory synapses, open excitatory.
