Time-resolved tmFRET revealed structural and energetic changes induced by ligand binding with full agonist cAMP and partial agonist cGMP in the cyclic nucleotide-binding domain of the bacterial ion channel SthK.
The perception of ambiguous steps in relative tone height is predicted by direction-selective cells in the auditory cortex, rather than the brain's represented distance between the tone heights.
The visual information walkers use for path selection during locomotion was revealed by analysis of a three-dimensional numerical representation of the natural terrain.
