Acetylcholine, a common modulator in the brain, controls spike-frequency adaptation by specifically attenuating Ether-a-go-go related K+ currents, thereby explaining many cortical network statistical changes often observed in vivo.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
A direct relationship between pupil diameter and electrophysiological correlates of attention, sensory stimulus processing and target detection was observed demonstrating that arousal has a substantial influence on perceptual decision-making.
The pattern of spatial attention preferences in caudate neurons is altered by superior colliculus inactivation, demonstrating that a superior colliculus to basal ganglia link is important for selective attention.
A computational model reveals how response properties of category-selective regions in the visual cortex reflect both bottom-up stimulus-driven signals and top-down attentional signals from the parietal cortex.
