Positive feedback triggers a reward signal in the brain, reinforcing the action that caused it, and making it more likely to be repeated in the future.
That's not surprising, considering difficult feedback triggers the amygdala, a part of the brain responsible for the fight-or-flight response.
It is applicable when a system is involved in a closed signaling loop, i.e., action by the system generates an environmental change that is reflected in the system in some manner (feedback), triggering a system change.
The sublime Xbox One pad, with its rumbling force feedback triggers, gives you a decent impression of exactly how your car is performing on the track.
Thus subtle feedback responses triggered by changes in chromatin configurations impinge selectively on linker histone mobility and its expression.
Lastly, consideration is paid to complex feedback effects triggered by the network users or operator.
However, released NGAL has not only bacteriostatic functions, but also has an important role in the maturation and activation of neutrophil granulocytes [34, 35], i.e., NGAL-mediated neutrophil activation is a positive feedback loop triggered by e.g., endotoxemia.
If the input ceases later for instance, in response to a feedback signal triggered by the firing of the target the "most economical" way of delivering input (the way that requires the least total amount of input) is no longer precisely synchronous, but merely approximately so.
