Fig. 10From: Cellular properties of intrinsically photosensitive retinal ganglion cells during postnatal developmentComparison of light response properties of ipRGC subtypes across development. a, b Maximum light response of M1, M2, and M4 ipRGC subtypes at P6 (a) and Adult (b). c, d Light onset for M1, M2, and M4 ipRGC subtypes at P6 (c) and Adult (d). Light onset was defined by time to reach 50% of maximum depolarization. Graphs are Mean ± SD, n = 5–14 per subtype/age, *p < 0.05Back to article page
