Actually, discriminating between positive and relaxed negative selection is not an easy task; even so, since the het1 region is functionally important we cannot completely discard that positive selection might in fact also drive the evolution of D. guanche OS-E gene.
It might bring improvements but also drive up his rent and banish him from Boyle Heights.
Another possible confounding might be that functional couplings associated with O R encoding strength might primarily engage in error-driven S R learning, which might as a side effect also drive O R learning (possibly even elsewhere in the brain).
Because the coherence appears only when movements are voluntarily driven, the common subcortical oscillator might also be driven by descending inputs from the cerebral cortex and/or by peripheral feedback associated with the movement.
As we now know that BT virus dynamics are predominantly driven by environmental conditions (e.g. temperature, and vector habitats) [9] but might also be driven by housing systems or other factors this is a questionable assumption.
