In positive feedback, the level of the original signal is increased and amplified until it is no longer needed, often requiring an external interruption. Example of Negative Feedback Loops Negative feedback loops control the concentration of several important hormones like thyroxine, insulin, and glu...

Finding positive meaning in past negative memories is associated with enhanced mental health. Yet it remains unclear whether it leads to updates in the memory representation itself. Since memory can be labile after retrieval, this leaves the potential fo
Insomuch as the early attendance to negative self-relevant information occurs rapidly, it may be that complementary and adjunctive approaches to standard therapeutic interventions—e.g., real-time neurofeedback aimed at modulating the default mode network (DMN), which is implicated in self-...
For example, a previous exploration of a retinal subunit model with temporal filtering and feedback30, which applied a global optimization approach for all model parameters, had to restrain the parameter space by enforcing identical shapes of subunits and restricting the analysis to a single spatial...

For example, estrogen induced the expression of the miR-1792 family of microRNAs, which can restrict estrogen actions in feedback through different ways. Meanwhile, several microRNAs like miR-18a, miR-19b, and miR-20b can directly downregulate ERα expression and other microRNAs such as miR-...
