Brightness processing in the visual cortex by Salmela, Viljami R., Laurinen, Pentti I.

“…Single cell recordings have shown that some cells in the primary visual cortex (V1) signal surface brightness. However, fMRI experiments have found brightness…”

Spatial frequency difference between textures interferes with brightness perception by Salmela, Viljami R., Laurinen, Pentti I.

“…Abrupt changes in luminance trigger and restrict brightness filling-in. If brightness was actively filled-in and mediated by cells signaling both luminance…”

Spatial frequency tuning of brightness polarity identification by Salmela, Viljami R, Laurinen, Pentti I

“…Recent studies have shown that cells in the primary visual cortex can, in addition to borders, also encode surface brightness. Whether the brightness is…”

Multiple gain control processes in contrast–contrast phenomena by Olzak, Lynn A, Laurinen, Pentti I

“…Spatial interactions among orientation-tuned gain control processes are presumed to mediate center-surround contrast–contrast phenomena. In this paper, we…”
