Administration of LSD to mice (0.5 mg / kg, ip) led to a significant increase in fos-like immunoreactivity in the rat PFC and ACC that was completely blocked by scheduled treatment with specific antagonist 5-HT2A MDL100907 (Gretsch et al., 2002) . Shrooms Vs Acid
Duplicate staining of both foes immunoreactivity and 5-HT2A receptor reveals that LSD did not create foes in pyramidal cells that express 5-HT2A receptors in the PFC or parietal cortex. Expanded fos expression has been introduced into the left cells in Shrooms Vs Acid III and IV, with the abnormal appearance of a double-labeled pyramidal cell, which promotes the induction of foes in some indirect way.
Based on work
From the Aghajanian laboratory (Aghajanian and Marek, 1997; Marek and Aghajanian, 1998a), the authors speculate that this opening may result in glutamatergic thalamocortical input.
In vivo microdialysis after systematic administration of DOI revealed a significant thegaiavoice.com in extracellular glutamate in the rat somatosensory cortex (Scruggs et al., 2003). Intracortical reverse dialysis of.

After intracortical DOI was blocked by selected 5-HT2A antagonist M100907. Similarly, using microdialysis, extracellular glutamate also significantly increased in rat PFC for 30 minutes after administration of intraperitoneal LSD of 0.1 mg / kg and continued for 30 minutes.

A study by Lambe and
Aghajanian (2006) also examined the basis for a recent improved wave of extra synaptic transfer of glutamate to PFC brain fragments in mice. They slow down the distribution of glutamate beyond the synapse by increasing the viscosity of the outer space using a dextran solution, a process known as suppressing.
They also examined subtypes of N-methyl-d-aspartate (NMDA) receptors involved in the recent wave of glutamate production produced by LSD and DOI. They found that a 5% solution of dextran solution significantly reduced LPSD-induced LPSD or DOI mushroom changing the EPSC rapidly.
Of EPSCs (UP regions) by dextran has suggested that the recent wave of glutamate release caused by psychedelics stimulates extra synaptic, rather than synaptic, glutamate receptors. Therefore, NMDA receptor subtype 2B Ro25-6981 [(αR, βS) -α- (4-hydroxyphenyl) -β-methyl-4- (phenylmethyl) -1-piperidinepropanol] and fenprodil significantly suppressed The latest EPSC Shrooms Vs Acid by DOI.
but it did not contribute to the rapid EPSC. The effect of psychedelics on UP regions may also be temporarily mimicked by a glutamate uptake inhibitor after blocking mGluR2 / 3. Their results show that psychedelics increase glutamate spillover in a phasic way.
