NMDA receptors require what in order to become activated?
glycine as well as glutamate, receptor function can be modifyed rather than a simple open or close mechanism
1 of 10
Criteria for NT
should posses machinery for synthesis and storage of substance, sub should be released from neurons by exocysosis, substance should interact with specific membrane receptors, mechanisms for inactivation should exist.

NM produce
slower pre-/post synaptic responses than NTs and produce ST/LT changes (neuronal gene modification). 100s-mins

Nitric Oxide
produced following a ride in intracellular calcuim . Once produce it is release immediated (not NT).
reacts with free readicals to produce peroxynitrile -> highly toxic -> neuronal death

Endocannibinoids
Retrograde messegers -> CB1 is a GPCR mediates THC. Examples anadimine and 2-Ag.
