Imaging action potentials with calcium indicators.
The understanding of neuronal circuits has been, and will continue to be, greatly advanced by the simultaneous imaging of action potentials in neuronal ensembles. This protocol describes "bulk" loading of brain slices with acetoxymethyl (AM) ester calcium indicators in order to monitor action potential activity in large populations of neurons simultaneously. The imaging of calcium influx into n...

cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injury, a common result of car accidents. induced functional motoneurons are an option for replacing the lost motoneurons. adipose derived stem cells (adscs) are an appropriate source of cells for autologous cell therapy with the ability of neural differentiation. in this study, adsc...
متن کاملDetecting action potentials in neuronal populations with calcium imaging.
The study of neural circuits requires methods for simultaneously recording the activity of populations of neurons. Here, using calcium imaging of neocortical brain slices we take advantage of the ubiquitous distribution of calcium channels in neurons to develop a method to reconstruct the action potentials occurring in a population of neurons. Combining calcium imaging with whole-cell or perfor...
متن کاملLarge-scale imaging of cortical network activity with calcium indicators.
Bulk loading of calcium indicators has provided a unique opportunity to reconstruct the activity of cortical networks with single-cell resolution. Here we describe the detailed methods of bulk loading of AM dyes we developed and have been improving for imaging with a spinning disk confocal microscope.
