retinotectal adjective anatomy specializeduk /ˌret.ɪ.nəʊˈtek.təl/ us /ˌret̬.ə.noʊˈtek.təl/ relating to the retina(= an area at the back of the eye that sends signals to the brain) and the optictectum(= part of the brain that receives signals about sight): The anatomical makeup of the zebrafish retinotectal system has been well documented. The superficial layers of the tectum are densely innervated by retinotectal axons. The retinotectal projection is generally regarded as an excitatory pathway. Retinotectal synapses typically contain densely packed, clear round vesicles and asymmetric synaptic structure. This receptor has been shown to play an important role in retinotectal pathway formation.
