An innovative inter-subject stimulus-locked brain activation approach uncovers marked topological differences in a brain network of higher-order visual regions in individuals with a congenital impairment in face recognition compared with controls.
Both bottom-up and top-down processing are involved in the occipital-temporal face network, with the top-down modulation more extensively engaged when available information is sparse in the face images.
Neurons in the fruit fly olfactory system respond most strongly to the sudden appearance of an odor, and to odors that are changing rapidly in strength, but are relatively insensitive to the absolute levels of an odor.
fMRI data from macaques suggest that sounds with similar temporal characteristics activate neighbouring regions of auditory cortex, giving rise to a topographic map broadly analogous to that for sound frequencies.
The spatial and dynamic properties of self-motion signals are acquired at the first stage of otolith signal transformation, which is in the brainstem and cerebellum, and conserved across brainstem, cerebellar and cortical areas.
