Olfaction is a chemoreception that forms the sense of smell. Olfaction has many purposes, such as the detection of hazards, pheromones, and food. It integrates with other senses to form the sense of flavor.[1]
Olfaction occurs when odorants bind to specific sites on olfactory receptors located in the nasal cavity.[2] Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.[3]
Often, land organisms will have separate olfaction systems for smell and taste (orthonasal smell and retronasal smell), but water-dwelling organisms usually have only one system.[4]

How do we identify different oderants, is it a result of different ligand receptors? Different concentrations of ion movements in the neuron? Or differences in neurone firing frequency?

Hii Matty...all oderants are received by group of olfactory receptors which comes under GPCRs n then onwards sent to brain n accordingly brain distinguishes smell based on behavioural and emotional perception.

@@mattywoods4313 ooh sad I couldn't help u much. Well in that case u may refer to good journals. I think in distinguishing smells "lateral horn" of brain plays an influential role. U might get it in Google scholar.
