Drugs that interfere with the formation of new neural networks in the brain's main memory center can cause short-term memory loss. Photo Credit woman in pain image by kuhar from Fotolia.com. Short-term memory is the ability to store sensory information for relatively short times, ranging from a few minutes to a few days.
As well as playing a secondary role in follicular responsiveness to FSH, LH is the trigger for ovulation itself. In response to the switch in estrogen mediated feedback from negative to positive, the LH mid-cycle surge is created. This activates a whole cascade of inflammatory responses in the dominant follicle leading to the breakdown of the follicular boundary wall and the escape of the oocyte with its cumulus oophorus.
In negative feedback loops, when the brain receives information about a change or deviation in the body's internal conditions, it sends out signals along nerves. These signals prompt the changes in function that correct the deviation and bring the internal conditions back to the normal range [1].47 progesterone receptors participate in the estradiol positive feedback mechanism, and thus regulating the LH surge onset [12]. Ovarian factors rather than exhaustion of pituitary reserves are suggested to be important for termination of the endogenous LH surge during the normal menstrual cycle [14]. 3.
