Dendritic release of dopamine in the substantia nigra
Dopamine can be released in the substantia nigra from the dendrites of nigrostriatal dopaminergic neurones, to be involved there in the self-regulation of the dopaminergic cells, to control the…
DARPP-32: Regulator of the Efficacy of Dopaminergic Neurotransmission
The results show that DARPP-32 plays a central role in regulating the efficacy of dopaminergic neurotransmission and is converted in response to dopamine into a potent protein phosphatase inhibitor.
Lack of autoreceptor-mediated inhibitory control of dopamine release in striatal synaptosomes of D2 receptor-deficient mice
In vivo presynaptic control of dopamine release in the cat caudate nucleus—II. Facilitatory or inhibitory influence ofl-glutamate
Glutamatergic Control of Dopamine Release in the Rat Striatum: Evidence for Presynaptic N‐Methyl‐D‐Aspartate Receptors on Dopaminergic Nerve Terminals
The results indicate that some of the NMDA receptors involved in the facilitation of DA release are located on DA nerve terminals, and these presynaptic receptors exhibit pharmacological properties similar to those described in electro‐physiological studies for postsynapticNMDA receptors.

Arachidonic acid markedly stimulated, in a dose‐dependent manner, the spontaneous release of [3H]dopamine ([3H)DA, continuously synthesized from [ 3H]tyrosine in purified synaptosomes from the rat striatum, indicating that AA both inhibits DA reuptake and facilitates its release process.
Release of dopamine in vivo from cat substantia nigra
Dihydroxyphenylacetic acid and homovanillic acid levels were increased after stimulation of the medial forebrain bundle, which contains axons of various ascending aminergic pathways including the nigrostriatal dopaminergic system, suggesting that dopamine could be released not only from nerve terminals in the striatum, but also from dendrites in the substantia nigra.
Release of dopamine evoked by electrical stimulation of the motor and visual areas of the cerebral cortex in both caudate nuclei and in the substantia nigra in the cat
