Calcium Imaging of Living Astrocytes in the Mouse Spinal Cord following Sensory Stimulation

Figure 3

Sensory stimulation triggers Ca2+ increase in spinal astrocytes. Section of superficial laminae of dorsal horn of lumbar spinal cord, showing two different astrocytes (a1, a2) in rest condition (a) and following sensory stimulation (b) (scale bar: 10 μm). (c) Quantitative analysis of astrocytic Ca2+ levels during rest and stimulation expressed as . The mean value of Ca2+ increase during stimulation was significantly higher than that measured during rest (rest versus stimulus, ).
