2. Figure 1 Mechanisms of Neuronal Homeostasis
Alternative 1—top pathway: A change in the number of red channels alters the cell's activity, and activity sensors in turn cause a change in the number of blue channels to compensate. Alternative 2—bottom pathway: Blue channels are regulated by red channel expression, so changes in the number of red channels automatically change the level of blue channel current.
