Hi, I am really new to patch-clamp recordings, and am trying to learn as much as posible by myself. I don't 100% understand how the patch-clamp recording works and so I don't really understand IPSC and EPSC traces. If an inhibitory post-synaptic potential is inhibiting and thus hyperpolarizing the neuron, why does the trace show positive changes in current amplitude? Is this because the voltage is being held constant but since the cell is becoming more negative a positive current is needed to hold the voltage study and that is the read-out of the experiment? And like-wise for negative EPSC traces. I am trying to fully understand a neuroscience paper and this is holding me back. Any help is really appreciated, thank you!
