There is a junction called synapse between the axon and the dendrite, and neurotransmitters enable neural information to across the synapse to achieve neural communication. After the neurotransmitters stimulate the receptors on the receiving neuron, excess chemicals are taking back up into the sending neuron to be used again (lecture). The reason that cocaine can induce euphoric rush is because it keeps dopamine,…show more content…
