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.
The first feedback loop is the blue one. In this loop, FSH and LH were secreted to start the development of the follicle. These two hormones work together to start estrogen secretion. The estrogen has a negative feedback on FSH, which causes it to stop being secreted. The second feedback loop is shown in red. This occurs with the increased amount of estrogen that is experienced at the midpoint in the cycle.
