Does stimulating severed axons in brain slice cause neurotransmitter release from those axons?

When you cut a slice, you sever many axons. So when you use your stimulating electrode (or a light in optogenetics) to evoke currents in the cell you've patched, can you evoke a response if the...

How exactly does current and voltage clamping work?

When patching a cell, what exactly is the electrode doing that "injects" current into the cell? If there's no literal injection of charge/current into the cell, how can the cell do things like...

What happens with constant current injection of neurons in current clamp?

With constant current pulses (lasting several hundred milliseconds), do neurons fire trains of action potentials or just one single action potential? Since voltage-gated Na+ channels can only...
