serotonin is believed as an important factor in brain function. the role of serotonin in cerebral psycho-patho-physiology has already been well established. however, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. methods: experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) who...

Objective(s): To investigate the effect of Ginkgo biloba extract EGb761 in early brain injury (EBI) after subarachnoid hemorrhage (SAH) and its mechanism. Materials and Methods: The SAH rat model was constructed and pre-treated with EGb761.The neurological function, severity of SAH, water content of brain tissue, damage degree of the blo...

In the 1960s, discovery of pleasure system (defined as reward system) in the brain that may underlie drug reward and addiction encouraged many scientists to investigate the mechanisms by which drug abuse affects central nervous system function. In this regard, investigators developed several drugs targeting the brain reward system for drug dependence therapy. However, no positive results obtain...

Background: Ensuring adequate depth of anesthesia during surgery is essential for anesthesiologists to prevent the occurrence of unwanted alertness during surgery or failure to return to consciousness. Since the purpose of using anesthetics is to affect the central nervous system, brain signal processing such as electroencephalography (EEG) can be used to predict different levels of anesthesia....
