‘How we smell’ explains the processes, mechanisms, and anatomy behind smell or olfaction. What is the dimensionality of smell? Ancient Greek and Roman philosophers argued that pleasant smells were made up of round atoms and unpleasant smells of pointed ones; while the detail is incorrect, the theory is accurate. When we smell something, olfactory neurons send a response into the brain where they converge with cells with the same receptor type to form a ball-shaped structure, the glomerulus. Higher order neurons then combine signals across glomeruli to extract olfactory information from the environment. All animals with a brain share this basic wiring diagram for detecting smells.

And Function

The olfactory system provides a great opportunity to explore the mechanisms that underlie the formation and function of neural circuits because of the simplicity of its structure. Olfactory sensory neurons (OSNs) located in the peripheral olfactory epithelium (OE) take part in the initial formation and function of glomeruli in the olfactory bulb (OB) inside the central nervous system. Glomeruli are key in the process of transduction of olfactory information, as they constitute a map in the OB that sorts the different types of odorant inputs. This odorant categorization allows proper olfactory perception, and it is achieved through the anatomical organization and function of the different glomerular circuits. Once formed, glomeruli keep the capacity to undergo diverse plasticity processes, which is unique among the different neural circuits of the central nervous system. In this context, through the expression and function of the odorant receptors (ORs), OSNs perform two of the most important roles in the olfactory system: transducing odorant information to the nervous system and initiating the development of the glomerular map to organize olfactory information. This review addresses essential information that has emerged in recent years about the molecular basis of these processes.
