Dichoptic colour-saturation masking is unmasked by binocular luminance contrast
We demonstrate a new type of interaction between suprathreshold colour (chromatic) and luminance contrast in the context of binocular, specifically dichoptic vision. A highly saturated isoluminant violet 'mask' disk in one eye greatly elevates detection thresholds for an isoluminant violet 'test' disk in the other eye, an example of dichoptic colour-saturation masking. However when binocular lu...
متن کاملCourage Unmasked
Lying supine, the technician uses my mask to bolt me to the treatment table. After he leaves the room, I feel alone, and at first, afraid. I see and hear the radiation machine move around me, but feel nothing. Minutes later, the door opens, and the mask is unbolted. This process is repeated almost daily for 2 months... After 2 weeks, the skin on my neck and inside my mouth becomes red, sore, an...
متن کاملThe torso ligand, unmasked?
When a transmembrane receptor protein tyrosine kinase (RTK) is expressed throughout the plasma membrane, yet only a specific handful of them must be activated, what's a ligand to do? During the development of the anterior and posterior termini of the Drosophila embryo, uniformly secreted ligand precursors are activated by proteolysis near the location of the receptors that must be activated. St...
متن کاملThe Negative BOLD Signal Unmasked
Many fMRI experiments show regions of cortex that seem to respond in antiphase with the primary stimulus. In this issue of Neuron, Shmuel et al. show that this "negative BOLD response" is spatially and temporally linked to reductions in blood flow. By combining BOLD and blood flow data to model the energy consumption in cortex, they conclude that the NBR is primarily due to active neuronal inhi...
متن کاملHypoparathyroidism unmasked by alendronate.
The case of an elderly woman is reported in whom alendronate, given for osteoporosis, led to severe hypocalcaemia a few days after starting the drug treatment. This was caused by the unmasking of previously unrecognised hypoparathyroidism.
