Neural transmission (information being sent from neuron to neuron) works at both the electrical and chemical levels. When the space between two neurons is small enough the electrical signal can simply jump the gap and continue on its way. However, when the gap is too large, the signal must be converted from electricity to chemicals. These chemicals are neurotransmitters, which can be defined as chemicals released by neurons which carry information from one neuron to another. These chemicals are then read or received by a neuron's synapses.
