Summary Introduction

To compare: The excitatory and inhibitory signals from neurotransmitters and their effect.

Introduction: Signal transduction is possible because of specialized nerve cells called neurons. The neurons are not physically joined together, so at neuron junction, signal is transmitted by a neurotransmitter molecule. Neurotransmitters can have different effects on binding to different receptors. Even on the same receptors, different neurotransmitters binding produce a different effect.
