摘要：
Mayo JP. Intrathalamic mechanisms of visual attention. J Neurophysiol 101: 1123-1125, 2009. First published January 14, 2009; doi:10.1152/jn.91369.2008. The classical model of visual processing emphasizes the lateral geniculate nucleus (LGN) as the major intermediary between the retina and visual cortex. Yet, anatomical findings inspired Francis Crick to suggest an alternative model in which the thalamic reticular nucleus, which envelops the LGN, acts as the "guardian" of visual cortex by modulating LGN activity. Recent work by McAlonan and colleagues supports Crick's hypothesis, thereby enhancing our understanding of the early stages of visual processing.
