2. Figure 1 Size-selective circuits in the zebrafish optic tectum.
Circuits dedicated to processing large and small visual stimuli are colour-coded green and magenta, respectively. Retinal ganglion cell axons selective for small (prey-sized) and large visual stimuli target the stratum opticum (SO) and stratum fibrosum et griseum superficiale (SFGS) layers of the tectum, respectively. Superficial interneurons (SIN) selectively sample retinal ganglion cell inputs: superficial interneurons tuned to small objects project arbours to stratum opticum, while superficial interneurons tuned to large objects project to stratum fibrosum et griseum superficiale. The postsynaptic targets of superficial interneurons are unknown. Size tuning is also evident in periventricular neurons. The presynaptic and postsynaptic targets of the size-tuned periventricular neurons are unknown but these may feed into locomotor circuits that drive approach or avoidance behaviours.
