comment How does an inhibitory synapse communicate to the cell body of a neuron?
I wish I could "accept" both your answer and yamad's answer ;-). Thanks again for a great answer...

comment How does an inhibitory synapse communicate to the cell body of a neuron?
I had read about EPSPs and IPSPs before and I now see that the main difference is the sign of the delta voltage change - thanks. My question still remains about how these travel down to the cell body down the dendrite tree. These are not action potentials and I thought action potentials were required for signals to travel unchanged over any distance. Do these EPSPs and IPSPs travel unchanged down the dendrite tree to the cell body to get "summed"? The membrane potential near the synapse changes but how does that change travel down the dendrite? The dendrite is not an electrical conductor.
