"The white elements in the picture are the axons from the olfactory sensory cells located at the front of the brain. They carry information about different molecular components of odors. The red parts are the synaptic terminals that are located inside of these axons and these terminals are the cellular sites at which neural information (i.e., action potentials or electric signals) are converted into a chemical signal which then moves over to another neuron and activates it."
