We have described activity-dependent dynamic properties of the Martinotti-cell inhibitory feedback loop in the presubiculum. These properties underlie a self-sustained processing of head direction ...

The new work demonstrates that the sensitivity of MSO neurons to ITDs is modulated via a feedback loop that involves receptors for the inhibitory neurotransmitter gamma-amino butyric acid (GABA).

This allowed the germinal center-Tfh cells that received sustained T-cell receptor signaling and were producing IL-2 to circumvent the T-cell receptor/IL-2-inhibitory feedback loop because the ...

PER2 protein is at the center of the inhibitory feedback loop that underlies the molecular mechanisms that control circadian rhythms, but its importance goes beyond just regulating sleep.

It appeared that the higher the level of PER in a cell, the less would be produced, creating an inhibitory feedback loop that essentially allowed PER to regulate its own levels throughout the day.

The voltage pulse, in turn, passes through a feedback loop to stimulate the inhibitory interneurons as well. These respond by damping the pyramidal cells themselves – which is called inhibitory ...

They reasoned that by an inhibitory feedback loop, PER protein could prevent its own synthesis and thereby regulate its own level in a continuous, cyclic rhythm. Such a regulatory feedback ...

The new direct feedback loop, however, in response to the same range of incoming signal strength, was found to recruit strong inhibition in brain cells (neurons) in EC layers 2 and 3, never ...

Memories may be maintained in the brain through a mechanism familiar to any engineer — negative and positive feedback loops, according to researchers ... either positive (excitatory) or negative ...
