Primes¶
- Feedforward Inhibition
- In neuroscience, the origin, thalamocortical and hippocampal circuits use feedforward inhibition to enforce narrow temporal integration windows: an afferent excites a target cell directly and drives an interneuron that inhibits the same cell a moment later, so inputs inside the window summate and later inputs are clipped, producing precise timing and sparse coding.
This sourceDemonstrates disynaptic feedforward inhibition imposing a narrow (<2 ms) temporal integration window on hippocampal pyramidal cells via the short delay of disynaptic inhibition following monosynaptic excitation — the canonical feedforward-inhibition microcircuit.

The abstract states a narrow (<2 ms) somatic integration window set by disynaptic feed-forward inhibition after monosynaptic excitation; it does not mention sparse coding.
“Here, we show that in rat hippocampal pyramidal cells this window is very narrow (less than 2 milliseconds). This narrowness results from the short delay with which disynaptic feed-forward inhibition follows monosynaptic excitation.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
