WebbAbstract. Olfactory receptors mediate the primary interaction of the olfactory brain with the external world. Any odor stimulus is initially represented as activation of one to many different olfactory receptors. Vice versa, anything that binds and activates an olfactory receptor is as per definition an odor, or odorant, as the single compounds ... WebbThe receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections. happy birthday card cake

Receptor Definition & Meaning - Merriam-Webster

WebbReceptors are protein molecules inside the target cell or on its surface that receive a chemical signal. Chemical signals are released by signaling cells in the form of small, usually volatile or soluble molecules called ligands. A ligand is a molecule that binds another specific molecule, in some cases, delivering a signal in the process.
