The concept of feedback mechanism was initially introduced in cybernetics to describe the ability of a control system to modify its output as a response to the input. In living systems, feedback mechanisms or feedback loops works to bring the body towards homeostasis by either amplifying a speci...
There are two types of feedback loops that assist the process of homeostasis: 1. Negative feedback loop Most homeostatic processes are maintained by negative feedback loops. Negative feedback loops result in an output that tends to minimize the effect of the stimulus in order to stabilize the ...

Also, given that the epigenetic state of chromatin and its conformation are thought to mutually affect each other in self-enforcing structure-function feedback loops [33], it seems likely that MLL fusions additionally alter chromatin organization by modifying its epigenomic profile. In infants, MLL ...

DNA loops bring distal regulatory elements near promoters, allowing ENHs to carry out their activating functions. ENH-promoters’ specificity is ensured by insulator elements localized within the ENH-promoters’ domain boundaries and blocks the spread of ENHs’ signals to unrelated genes [17]. ...
Dubstepis a type of electronic dance music that focuses on bass-heavy, rhythmic loops to build a repetitive melody. Although it is primarily instrumental, short lyrics may occasionally be recorded over a looped beat. Chaotic in nature, this genre focuses on creating dramatic build-ups that lead...
Reward processing is a fundamental human activity. The basal ganglia are recognized for their role in reward processes; however, specific roles of the different nuclei (e.g., nucleus accumbens, caudate, putamen and globus pallidus) remain unclear. Using quantitative meta-analyses we assessed whole-...
which likely contributes to their establishing and maintaining functional loops between the frontal cortex, basal ganglia, and thalamus. However, less is known about how GABAergic neuron subpopulations are selectively incorporated into cortical circuits or how they might differentially regulate cortical ...
