How does alpha 2 antagonism work in regard to norephinephrine?
Normally, norepinephrine (NE) lands on the presynaptic alpha 2 receptor, and the system ‘thinks’ there is plenty of NE, so this leads to decreased NE. An alpha 2 antagonist blocks NE so the system thinks there is not enough NE, and NE increases.
How does alpha 2 antagonism work in regard to serotonin type neurons which have presynaptic alpha 2 receptors on them (i.e. heteroreceptors)?
Normally NE lands on the alpha 2 site leading the system to decrease serotonin release. When an alpha 2 antagonist lands on the site it leads to increased serotonin release

What does the presence of serotonin in the synaptic space lead to?
Postsynaptic receptors become desensitized (2a, 2c, 3). These receptors send information to the cell nucleus of the postsynaptic neuron resulting in the instruction to downregulate these receptors. The time course for this to happen corresponds to the tolerance of side effects.
The increased ratio of serotonin to serotonin receptors after antidepressant treatment as a mechanism of action is supported by what evidence among other?
Deceased suicidal and otherwise depressed patients have had more 5-HT2A receptors than normal patients. These considerations suggest that 5-HT2A overactivity is involved in the pathogenesis of depression.
What serotonin receptor does trazadone block?
5HT2a receptor. It also blocks reuptake but less so than other agents
By what process does trazodone effet sleep?
By inhibiting histamine H1 leading to sedation and by inhibiting 5HT2a which induces and restores slow wave sleep

Cell bodies in the raphe nuclei and not at the axon terminal where the re-uptake pump is located (somatodendritic autoreceptors 5HT1a)
Increased serotonin at the somatodendritic autoreceptor 5HT1a leads to?
Downregulation and densitization. Once desensitized and down regulated it can no longer efffectively inhibit its own release and the serotonin neuron is disinhibited. This correlates with time of onset of anti-depressant action

5HT1a and therefore anxiolysis, antidepressant effects
How does alpha 2 antagonism increase the release of serotonin?
The locus coeruleus has norepinephrine neurons stimulating alpha 1 receptors in the midbrain which stimulates release of serotonin. When alpha 2 is antagonized this disinhibits release of norepinephrine. The norepinephrine stimulates alpha 1 which stimulates serotonin release
