| Do hallucinogenic drugs produce tolerance? |
|
Definition
| With the exception of DMT, most hallucinogenic drugs produce rapid tolerance with repeated use. (possibly down regulation of 5-HT2A receptors) |

|
Definition
| The locus coeruleus (dense cluster of NE-containing neurons in the pons that is responsible for most of the noradrenergic projections to the forebrain) b/c LSD, DOM, and mescaline all decrease spontaneous firing of LC neurons but enhances the excitation of the neurons (LC more sensitive to sensory input) |

|
Definition
| Hallucinogen-appropriate lever choosing is reduced (effects go away) |
|
|
Term

|
Definition
| the cortex (remember: postsynaptic, Gq-coupled, espcially on pyramidal neurons) |
|
|
Term
| True/False: Both indoleamine and phenethylamine hallucinogens appear to act as 5-HT2A agonists, BUT not all 5-HT2A agonists are hallucinogenic. |
|

|
|
Term

|
Definition
| All 5-HT2A agonists regulate PLC via Gq |
|
|
Term
| Hallucinogenic drugs, like all 5-HT2A agonists, regulate PLC via Gq, as well as...How is this possible? |
|
Definition
| as well as engage a Gi/o-coupled pathway..this is possible by mGluR2 (target receptor for anti-psychotic meds) which Gi/o coupled, binds with 5-HT2A receptors |
