Yohimbine-related Alkaloids from
Five new yohimbine-type indole alkaloids were isolated from the leaves of Tabernaemontana corymbosa . Their structures were determined on the basis of the NMR and Circular Dichroism (CD) spectroscopy.

Noradrenergic control of error perseveration in medial prefrontal cortex
The medial prefrontal cortex (mPFC) plays a key role in behavioral variability, action monitoring, and inhibitory control. The functional role of mPFC may change over the lifespan due to a number of aging-related issues, including dendritic regression ...

Basal cortisol level modulates stress-induced opioid-seeking behavior
In preclinical studies and our human laboratory, the α2-noradrenergic autoreceptor antagonist yohimbine was found to promote drug-seeking behavior. This study evaluated effects of dose-combinations of yohimbine and the glucocorticoid receptor agonist ...

The Role of Mitochondrial Biogenesis and Α2-Adrenergic Receptors of the Hippocampal CA1 Region in Morphine-Induced Memory Impairment [PDF]
Background and Objective: Mitochondrial biogenesis and the adrenergic system play an important role in cognitive processes. The dorsal hippocampus (CA1) has a high distribution of α2-adrenergic receptors.
