- Movie 1
-
Movie 1. Calcium transients in Müller cells. Calcium fluorescence is imaged within glial cells at the inner (vitreal) surface of the retina. Transient increases in Ca2+ within individual Müller cells are seen. The brightly labeled cells with unvarying Ca2+ are astrocytes. The movie is shown at five times normal speed.
- Movie 2
-
Movie 2. Light-evoked Müller cell Ca2+ increase potentiated by adenosine. Calcium fluorescence is imaged within Müller cells in the ganglion cell layer. In the presence of 100 ?M adenosine, light ON (indicated by the yellow circle) evokes a large transient increase in Ca2+ within all Müller cells. The movie is shown at normal speed.
- Movie 3
-
Movie 3. Intercellular propagated Ca2+wave evoked by light. Calcium fluorescence is imaged within Müller cells in the ganglion cell layer. Following light ON (indicated by the yellow circle), there is a large transient Ca2+ increase within all Müller cells. A secondary rise in Ca2+ occurs in 2 Müller cells 14 s after light ON. This secondary Ca2+ increase then propagates into several additional Müller cells. 100 ?M adenosine in superfusate. The movie is shown at normal speed.
