Suppressive neural influences aggregate mechanical, adaptive, and refractory effects together.

Evidence

Positively and negatively weighted vectors are interpreted as excitatory and suppressive influences, respectively (Rust et al. 2005 ; Schwartz et al. 2006 ; Sneary and Lewis 2007 ). However, mechanical suppression, adaptation, and refractory effects may all contribute to what we term “suppressive” influences. To determine statistical significance of each weighted vector, we re-computed h 2 from 20 different spike:train randomizations, conserving the first-order inter-spike-interval distribution. Based on this bootstrap distribution, weights were expressed as z-scores, and any vector with |z| > 3 and rank ≤ 20 was considered significant. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3842 (#exemplifies, via linked claim)
