Laminar organization of tree shrew dorsal lateral geniculate nucleus.

abstract：:Recent studies have shown that the initial responses evoked by a stimulus in neurons of primary visual cortex are dominated by low spatial frequency information in the image, whereas finer spatial scales dominate later in the response. Such phenomena could arise from the dynamics of receptive field (RF) size at early ...

Phase-locking of neurons in the anteroventral cochlear nucleus (AVCN) is usually reported to be less robust than in auditory nerve (AN) fibers, which provide their major input. In a companion...
