Building on previous work (Metzen et al., 2016), a combination of neurophysiological and behavioral approaches reveals that changes in the background strongly impacts invariant coding and perception of behaviourally relevant signals.
Cerebellar Purkinje neurons use a multiplexed simple spike code combining synchrony/spike time and firing rate, with each component encoding distinct information about movements such as motion onset timing and kinematics.
A new statistical approach identifies non-coding regulatory regions of genes as driver candidates with recurrent mutations across cancer samples that associate with gene expression, patient survival or mutational phenotype.
Neurophysiological and behavioral approaches reveal how coordinated input from descending pathways shapes the tuning properties of electrosensory neurons in order to optimize coding of natural stimuli through temporal whitening.
Whether central vestibular neurons implement faithful stimulus encoding for the vestibulo-occular reflex or optimized coding via temporal whitening for other vestibular functions is determined by neural variability.
Softer sound appears closer to midline than louder sound, conflicting with a labelled-line representation of auditory space and supporting the idea that humans use rate coding when calculating sound directionality.
