Changes in physiological arousal – as revealed by pupil dilation and heart rate – shape our confidence in decisions about uncertain perceptual information.

Rather than complex decisions, it is the motion of individuals that allows for collective foraging regulation in ant colonies.

Primary motor cortex afferents supra-linearly amplify the responses and sharpen angular tuning of neurons in the S1 barrel cortex.

A high-throughput enhancer-enhancer-promoter reporter assay indicates that pairs of enhancers generally activate promoters in a near-additive manner, and that promoters transform their collective effect non-linearly.

The human visual system groups the individual features of objects together into a coherent whole via a serial, attention-demanding process.

A combination of physiological and perceptual experiments show that the responses of rod photoreceptors inhibit those of cones more than vice versa, and reveal both the site of the retinal interaction and the underlying mechanism.

The frontal associative cortex promotes fear learning by non-linearly integrating Gaussian noise in between conditioning trials with the help of basolateral amygdala inputs.

Plants implement arithmetic division to optimize use of carbohydrate reserves and thus maintain metabolism and growth at night.

Separating behaviorally relevant signals from irrelevant signals reveals that neural signals previously considered to contain little information encode rich information and suggests that linear readout may be performed in motor cortex.

To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.
