At the conclusion of Barack Obama's State of the Union address on January 27, 2010, MSNBC anchor Chris Matthews lavished praise on the president, infamously gushing, “It's interesting: he is post-racial, by appearances. I forgot he was Black tonight for an hour.” According to many, this is the greatest of all Obama's super-powers; the ability to sweet-talk the public into a euphoric political hallucination, transporting followers into a world where he is cleansed of the stain of Blackness and the citizenry lives in racial harmony. If this is true, White voters, including Matthews, forgot Obama was Black long before the State the Union. By many accounts, this post-racial amnesia, rather than the nuts and bolts of voter mobilization, fundraising, message-crafting, or opponents' mistakes, ultimately resulted in Obama's victory in the 2008 election.

The saccules and ampullae of the semicircular canals from human and guinea pig temporal bones were fixed in glutaraldehyde without osmium. Crosslinks were seen between stereocilia of the vestibular hair cells, similar to those previously demonstrated in the guinea pig, although an additional set of crosslinks was displayed: first, horizontal crosslinks were seen between adjacent stereocilia, occupying most of the length of the hair bundle; secondly, a single upward-pointing link ran from the apex of each shorter stereocilium into the shaft of the adjacent taller ster-eocilium; thirdly, an extensive array of horizontal links were demonstrated between stereocilia close to their insertion into the cuticular plate. We suggest that these basal crosslinks support the long vestibular stereocilia rendering them more rigid, and that the upwind pointing crosslinks are responsible for the initiation of sensory transduction.

Human cochleae were fixed in glutaraldehyde, without the use of osmium. Crosslinks were seen between the stereocilia, similar to those we have previously reported for the guinea pig: first, stereocilia of the same row on each hair cell were joined by horizontally-running links; secondly, the shorter stereocilia had pointed tips, each giving rise to a single, vertically-pointing link, which ran upwards to join the adjacent taller stereocilium of the next row. We suggest that distortion of this link is involved in sensory transduction. The links were sparser than had been seen in the guinea pig which may be a reflection of the vulnerability of the links to nonoptimal fixation, and the greater difficulty in producing good fixation in human specimens.
