Refers to the over-reaction to symptoms exhibited by people who are suffering a panic attack (ie; thinking they're having a heart attack) and the subsequent increase in anxiety levels.
Note: Positive feedback is actually an electrical term meaning "feedback that results in the amplification or growth of the output signal." In terms of anxiety, this means the feedback (the symptoms) amplifies (worrying unnecessarily about symptoms) the output signal (increased anxiety).
The positive feedback loop is terminated by the end of childbirth...
positive feedback loop
negative feedback loop
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
positive feedback loop
- temperature - negative feedback loop - positive feedback loop - water balance
positive feedback loop because cause increases the effect. thank you very much!
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
Yes. Have fun proving it.
through what can be seen as the domino effect. when depolarization opens sodium ion channel and that results to the opening of more sodium ion channels. this creates a positive feedback loop.
It can contain active and passive components with a positive feedback loop.
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
