1 Some tissues, like the brain and eye, contain both receptors, but CB2 is found at a lower density than CB1 in these tissues. (drmicheleross.com)

As an information recipient, the postsynaptic neuron ultimately chooses whether to fire depending on the message it receives. (purplepenthouse.com)

A third subsystem of neurons has been named as non-noradrenergic, non-cholinergic transmitters (because they use nitric oxide as a neurotransmitter) and are integral in autonomic function, in particular in the gut and the lungs. (wikipedia.org)

This differential distribution of receptors on the presynaptic neuron is regulated by a target and does not require the physical presence of neurons that release the neuromodulators. (jneurosci.org)
Is the appropriate distribution of G-protein-coupled receptors regulated by interactions with neurons that synthesize and release the neuromodulator? (jneurosci.org)
But today, we know that every neuron can release two or more. (exploringyourmind.com)
