Recent evidence suggests that dopamine plays an important role in arousal, but the location of the dopaminergic neurons that may regulate arousal remains unclear. It is sometimes assumed that the dopaminergic neurons in the ventral tegmental area that project to the prefrontal cortex and striatum may regulate the state of arousal; however, the firing of these dopaminergic neurons does not corre...
AIM To study the changes of monoamines in ventrolatoral periaqueductal gray of rat brain before and after electroacupuncture (EA) analgesia (EAA) was enhanced by fenfluramine (Fen), a 5-hydroxytryptamine (5-HT) releaser. METHODS Monoamines were collected by in vivo microdialysis and measured by HPLC connected with electrochemical detector. RESULTS The level of norepinephrine (Nor) after EA ...

Introduction: Gestational diabetes induces developmental disorders in different parts of CNS and can change dimensions of the cerebrum, cerebellum and spinal cord. Different species of ginseng have been used for many years to control diabetes. This study investigated effect of extract of Panax ginseng on histomorphometric changes on cerebrum and cerebellum in 14 days offsprings rat from diabet...
