Olfactic communication is a channel of nonverbal communication referring to the various ways people and animals communicate and engage in social interaction through their sense of smell. Our human olfactory sense is one of the most phylogenetically primitive [ 1 ] and emotionally intimate [ 2 ] of the five senses ; the sensation of smell is ...
The molecules are delivered into communications media such as air and water for transmission. The technique also is not subject to the requirement of using antennas that are sized to a specific ratio of the wavelength of the signal. Molecular communication signals can be made biocompatible and require very little energy. [2] [3]
A semiochemical, from the Greek σημεῖον (semeion), meaning "signal", is a chemical substance or mixture released by an organism that affects the behaviors of other individuals. [1] Semiochemical communication can be divided into two broad classes: communication between individuals of the same species (intraspecific) or communication ...

The glow-in-the-dark bacteria communicate chemically about their numbers and only give off light when a cohort is large enough to create an effective light source. Bassler determined further that bacteria are "multilingual" and use multiple chemical signal molecules to communicate with each other. [2]
Atlantic salmon go a step further than detecting a predator's cue: when an individual is damaged by a predator, it releases a chemical cue to its conspecifics. [45] As has also been observed in other species, acidification and changes in pH physically disrupt these chemical cues, which has various implications for animal behavior .

Intercellular bridges are larger than gap junction ICCs so are able to allow the movement of not only small signaling molecules but also large DNA molecules or even whole cell organelles. They are maintained between two cells allowing them to exchange cytoplasmic contents and are frequently observed when cells need intimate communication such ...
