For a molecule to trigger olfactory receptor neurons, it must have specific properties.

How many receptor neurons in your retina?

Olfactory receptor neurons continue to be born throughout life and extend new axons to the olfactory bulb.

There are millions of olfactory receptor neurons that act as sensory signaling cells.

Each glomerulus collects information from a specific olfactory receptor neuron.

It's thought that this response is due to a single auditory receptor neuron, which fires away when a bat call is heard.

In insects, olfactory receptor neurons typically reside on the antenna.

Averaged activity of the receptor neurons can be measured in several ways.

In response to leptin, receptor neurons have been shown to remodel themselves, changing the number and types of synapses that fire onto them.

It is a highly expressed, cytoplasmic protein found in mature olfactory sensory receptor neurons of all vertebrates.
