This is called a neurotransmitter. While the predominant neurotransmitter in the brain is glutamate, this question could better be phrased as which compound doesn't act as neuromodulator or neurotransmitter. Transmitters such as Substance P, Neuropeptide Y are less known, but aspartate, acetylcholine, glycine, epinephrine which are neurotransmitters elsewhere in the body are also transmitters to some extent in the brain as wel.
Yes the brain communicates using nerotransmitters . Nerotransitters are the chemicals released at synapses in your neurons. It works like this the electrical signal passed through neurons changes from chemical to electrical when it moves from neuron to neuron. At the end of a neuron (which is call the axon terminal) the electrical signal triggers the production of chemicals that will be released out in to the small gap between neurons as no neurons actually touch. The gap is called the synaptic cleft. Then receptor proteins on the dendrites of the adjacent neuron will pick up the chemicals and signal the next neuron to fire, thus sending the signal to along. This all happens incredibly fast between 3 and 120 metres per second in myelinated fibres actually.

Communication between cells.
Intercellular means between cells;as, intercellular substance,space,or fluids.
The sticky material between cells of areolar connective tissue is known as "ground substance."
a substance that is located on the surface of white blood cells. This substance plays an important role in the body's immune response.
cell membranes
Communication between cells.
Receptors are important because they play a key role in cell signaling. They allow communication between the cells to facilitate cellular processes.

Neurotransmitters are chemicals released from nerve cells that play an important role in nerve cell communication.
