Pairing a stimulus in one modality (vision) with a stimulus in another (sound) can lead to task-induced hallucinations in healthy individuals. After many trials, people eventually report perceiving a nonexistent stimulus contingent on the presence of the previously paired stimulus. Powers et al. investigated how different groups of volunteers and patients respond to this conditioning paradigm. They used behavior, neuroimaging, and computational modeling to dissect the effect of perceptual priors versus sensory evidence on such induced hallucinations. People who are more prone to hear voices were more susceptible to the induced auditory hallucinations.
Céline Dion recently revealed that she still senses the presence of her husband, even though he died from cancer in January 2016. What's more, the Canadian singer said she still talks to René Angélil, who she was married to for 22 years, and can still hear him at times. While her remarks prompted ridicule in some quarters, seeing, hearing or sensing the presence of a deceased loved one is nothing to be ashamed of. On the contrary, it is a perfectly normal and often helpful way of dealing with grief. Sensing a deceased spouse is remarkably common.
Face hallucination method is proposed to generate high-resolution images from low-resolution ones for better visualization. However, conventional hallucination methods are often designed for controlled settings and cannot handle varying conditions of pose, resolution degree, and blur. In this paper, we present a new method of face hallucination, which can consistently improve the resolution of face images even with large appearance variations. Our method is based on a novel network architecture called Bi-channel Convolutional Neural Network (Bi-channel CNN). It extracts robust face representations from raw input by using deep convolutional network, then adaptively integrates two channels of information (the raw input image and face representations) to predict the high-resolution image. Experimental results show our system outperforms the prior state-of-the-art methods.
"Scorpion" Season 3, episode 17 will focus on Cabe (Robert Patrick), Sylvester (Ari Stidham) and Happy (Jadyn Wong) experiencing hallucinations during their newest mission. In the sneak peek released by CBS for "Dirty Seeds, Done Dirt Cheap," the trio is tasked to protect a vital seed. But when their mission goes awry, Cabe, Sylvester and Happy suffer from life-threatening, fear-based hallucinations. Sylvester, who is scared of being chased, imagines that he is being followed. Cabe, who fears getting old, hallucinates that he's approximately 10 years older with a wrinkled face.
