Using two-photon calcium imaging<\/span><span> in awake mouse thalamus, <\/span><span>we observed <\/span><span><\/span><span>a functional arrangement of retinal ganglion cell axonal boutons in which coarse-scale retinotopic ordering gives way to fine-scale organization based on shared preferences for visual features such as axis or direction of motion, spatial frequency, and\/or changes in luminance. Specifically, at the ~6 <\/span><span><\/span><span>micron scale, clusters of boutons from different axons often showed similar preferences for either one or multiple features. Conversely, individual axons could &#8220;de-multiplex&#8221; information channels by participating in multiple, functionally-distinct bouton clusters. Finally, <\/span><span>ultrastructural analyses demonstrated that axonal boutons in a local cluster <\/span><span>often target the same postsynaptic dendritic domain. These data suggest that<\/span><span> functionally-specific convergence and divergence of retinal axons may impart diverse, robust and often novel <\/span><span>feature selectivity to visual thalamus.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Please join us at 11:30 AM for lunch at Boston University Photonics Center 8 Saint Mary&#8217;s Street Room 906, Boston, MA 02215 Registration is required Mark Andermann from the Beth Israel Deaconess Medical Center &amp; Harvard University will lead a discussion on &#8220;A fine-scale functional logic to convergence from retina to thalamus&#8221;.
