- High Speed Imaging of Membrane Potential using Voltage Sensitive Dye
- What is Voltage Sensitive Dye?
Voltage-sensitive dye changes its absorbance and fluorescence intensity when membrane potential changes in a stained brain or heart tissue.
By using voltage-sensitive dyes as chemical probes and capturing changes in light intensity with the use of a high-speed imaging device, it is possible to image in real time the activity of where, when, and how much excitation or inhibition occurred, in the brain and heart.
