(2007). Selective stimulation of astrocyte calcium in situ does not affect neuronal excitatory synaptic activity. Neuron 54, 611–626. doi: 10.1016/j.neuron.2007.04.032 Fiacco, T. A., and McCarthy, K. D. (2004). Intracellular astro- cyte calcium waves in situ increase...
A reverse process takes place during stimulation where charges are delivered from the electrode to affect membrane potential [[37], [38], [39]]. Stimulating neurons and recording extracellular signals can be achieved using a conducting electrode placed close to the cell or its processes [37]. ...
