    Notes: [Auszug] MORRONE ET AL. REPLY-For us the most intriguing aspect of Harmon and Julesz's1 ingenious demonstration is that blocking does not merely degrade the image, but renders recognition impossible. Normal masking (such as their Fig. 3a1 or indeed our Fig. 1d2) degrades the image but leaves it still ...

    Notes: [Auszug] In addition to the threshold measurements of temporal summation it is also well established that super-threshold stimulation leads to a sensation which persists in vision for some time after the termination of the stimulus4, again, for about 120 ms in daylight5,6. Perhaps the most direct ...

    Notes: [Auszug] Figure 1 Apparent position of a vertical bar briefly flashed at positions - 20° (squares), 0° (triangles) or +20° (circles), as a function of time relative to saccade onset. Each point represents a single observation. Saccades from F0 to FT are indicated by the dashed line. The solid ...

    Notes: [Auszug] Observers viewed four-frame sequences of random dot displays, in which a proportion of dots were appropriately displaced between frames, the remainder being replaced at random. The dots fell within a 10° circle, notionally divided into 16 equal sectors. Signal dots could be confined to ...

    Notes: [Auszug] SIR - The scholarly analysis of Katsikis and Leben (Nature 374, 670; 1995) seems to have turned the tide Funder's way on apoptosis. We write to point out that he unnecessarily weakened his own case in his opening letter (Nature 371, 98; 1994) by implying ...

    Notes: [Auszug] Mach originally7 used rotating discs and drums to study the bright and dark bands that appear where ramps of luminance meet plateaux as, for example, at the borders of the penumbra of a shadow. He later devised optical methods to cast shadows8. For the studies reported here we used gratings formed ...

    Notes: [Auszug] SIRá€"Your leading article "Bush declares war on drugs" (Nature 341, 1; 1989) is right in noting that if drug-related crime is to be totally eliminated, all drugs would have to be decriminalized, but it must be hoped that neither the United States, nor any other country for that ...

    Notes: [Auszug] A detail of Leonardo's 'Mona Lisa' was digitized into 256 x 256 pixels, using a flying spot scanning system made up of a Cromemco microcomputer, an oscilloscope (Hewlett Packard 1335A), a lens and a photometer (Spectra Pritchard 1980A). The digitized file was transferred to a larger computer ...

    Notes: [Auszug] The absorption of a photon by light-adapted bacteriorhodopsin (bRLA), the purple membrane protein of the Halo-bacterium halobium, initiates a series of transformations13, reminiscent of the bleaching sequence of rhodopsin. The primary photochemical product, K, is a bathochromically shifted species; ...
