In vivo microdialysis and single-cell extracellular recordings were used to assess the involvement of serotonin2A (5-HT2A) and serotonin2C/2B (5-HT2C/2B) receptors in the effects induced by amphetamine and morphine on dopaminergic (DA) activity within the mesoaccumbal and nigrostriatal pathways. The increase in DA release induced by amphetamine (2 mg/kg(More)
Previous studies of conventional tricyclic and non-tricyclic antidepressants have suggested that a number of these drugs display considerable pharmacological activity at 5-HT2C receptors in the brain. There is evidence that 5-HT2C receptors are involved in the control of the activity of the central dopaminergic system. Therefore, the effects of(More)
The activity of voltage-gated K+ channels (Kv) can be dynamically modulated by several events, including neurotransmitter stimulated biochemical cascades mediated by G protein-coupled receptors such as 5-HT2 receptors (5-HT2Rs). Activation of 5-HT2A/CR inhibits the Shaker-like K+ channels Kv1.1 and Kv1.2, and this modulation involves the dual coordination(More)
We analyze and compare five coronal regions simultaneously observed by NIXT and Yohkoh/SXT on April 12, 1993. The compact loop structures (length ∼ 109 cm) imaged in three regions with NIXT and with SXT have a good general morphological correspondence. A large scale (≈ 1.7×1010 cm) and an intermediate scale (≈ 5× 109 cm) structure observed in the NIXT image(More)
