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.
Answers. 1  There are actually countless feedback loops in the human body, so it would be quite difficult to pinpoint them all. Generally, though, positive feedback loops cause some kind of amplification, and negative feedback loops work to maintain conditions at a certain level. Furthermore, negative feedback loops generally work to shut themselves off, whereas positive feedback loops must be shut off by a different set of mechanisms. An example of a positive feedback system would be blood clotting. When you get injured, the damaged tissue releases chemical signals that activate platelets. These platelets release chemicals that activate other platelets, and so on and so forth, until lots and lots of platelets are activated and clots form. Once the clotting has been taken care of, separate signals are used to shut off the cascade. Negative feedback occurs in a lot of processes that maintain homeostasis.
