These findings suggest that cognitive pain modulation is altered in older age and that the preservation of executive functions may have beneficial effects on the efficacy of distraction from pain. Covariate analyses indicated that executive functions significantly predicted neural pain modulation in older adults: Better executive functions were associated with a more pronounced de-activation of the insula, thalamus and primary somatosensory cortex and increased activation of prefrontal regions during the high vs. low load task, when compared to young adults. Older adults, on the other hand, showed an increased activation in the anterior cingulate cortex during the high load vs. the low load task, such as the right insula, right mid cingulate cortex and left supramarginal gyrus, compared to older adults. Group comparisons revealed that young adults showed a stronger de-activation of brain regions involved in pain processing during the high load vs. In both age groups, completing the high load task was associated with a significant reduction in the perceived intensity and unpleasantness of painful stimuli and a reduction in activation of brain regions involved in pain processing. low) and concurrently received individually adjusted heat stimuli (warm vs. In a second session, we acquired functional brain images while participants completed a working memory task with two levels of cognitive load (high vs. In a first session, 30 healthy young (19–35 years) and 30 healthy older (59–82 years) adults completed a battery of neuropsychological tests. Yet, little is known about potential age-related changes in cognitive pain modulation, such as distraction from pain. Select Custom Mosaic Tiles from Mosaic menu.Growing evidence suggests that aging is associated with less efficient endogenous pain modulation as demonstrated by reduced conditioned pain modulation, and that these changes may be mediated by differences in frontal functioning. Mazaika Lite allows you insert your own image as a tile like a sort of signature or hidden picture riddle. To replace a tile image simply click on the tile with your right mouse button (or use Ctrl+ Click) and select a new image from popup menu. You may adjust how often every single image is repeated in mosaic, you may manually change and replace every tile in mosaic with a suitable candidate image from the library. To save mosaic press Export button, and select a needed output size.įor advanced users Mazaika Lite allows full control over mosaic creation. Mosaic can be saved as a jpeg image file. Resulted image changes will be visible in real time. Simply press Enhanced and adjust Blending and Correction levels. Mosaic can be enhanced with color corrections. main mosaic theme picture), or simply drop it into the program's screen from finder.ģ - Select how many rows and columns you want in your mosaic. You may use images from iPhoto or Aperture albums or images from folders on your hard disc.Ģ - Open source image (i.e. With Mazaika Lite you can fast and easy assemble a photo mosaic from your own images and save it into jpeg image file with longest side up to 4200 pixel.ġ - Create a library from your own images. From a distance this mosaic looks like one big image, but as you zoom in, it becomes clear that it's not just a single, large picture but rather a collection of small, separate images. Mazaika makes composite image from hundreds of smaller images.
