Stereoscopic corrugation detection in the presence of horizontal- and vertical- additive disparity noise was examined using a signal detection paradigm. Random-dot stereograms either represented a 3-D square-wave surface with various amounts of Gaussian-distributed additive disparity noise or had the same disparity values randomly redistributed. Stereoscopic detection of 2 arcmin peak amplitude corrugations was found to tolerate significantly greater amplitudes of vertical-disparity noise than horizontal-disparity noiseirrespective of whether the corrugations were horizontally or vertically oriented. However, this directional difference in tolerance to disparity noise was found to reverse when the corrugation and noise amplitudes were increased (so as to produce equivalent …

B lymphocytes are known to synthesise the P2X(7) subtype of the P2X purinergic receptor family; however, the identification of the other six P2X subtypes on these cells has been limited by the absence of specific antibodies. In this study, we used a panel of anti-P2X polyclonal antibodies and confocal microscopy to examine the presence of each P2X receptor on human B lymphocytes. We observed that P2X(1), P2X(2), P2X(4) and P2X(7) subtypes, but not P2X(3), P2X(5) and P2X(6) subtypes, are present on B lymphocytes.
