Fig. 1. Group-mean percent-correct recognition of the target keywords for the health-control participants (top panel) and patient participants (middle panel) as a function of signal-to-masker ratio (SMR) along with the group-mean best-fitting psychometric functions under the no-priming condition (open triangles and dash curve), false-priming condition (open squares and dash curve), and true-pri...

The pathogenesis of complex visual hallucination by suppression of inhibitory cortical input to visual association areas is considered as the “release phenomenon”. A 79 year-old man without dementia or hallucinations history experienced complex visual hallucinations in the right lower quadrantanopia area after traumatic subdural hematoma (SDH) of the left occipital region. The vivid hallucinati...

Pure word deafness is a disorder of auditory verbal comprehension without dysfunction of speaking, reading, or writing. This rare symptom arises from bilateral lesions in the temporal lobes or disconnection between the primary auditory cortex and Wernicke’s area. I present a right-handed 33-year-old woman who presented with pure word deafness and complex auditory hallucination with intermittent...

This study developed a face hallucination system based on a novel two-dimensional direct combined model (2DDCM) approach that employs a large collection of low-resolution/high-resolution facial pairwise training examples. The proposed 2DDCM approach achieves face hallucination by addressing three key issues. First, we directly combine each low-resolution and high-resolution pairwise image in a ...

The analysis presented in 1972 by R. F. Q. Johnson, B. A. Maher, and T. X. Barber indicated that nonhypnotic 5s manifest trance logic as often as "real" hypnotic 5s. E. R. Hilgard's 1972 critique contended that the analysis was misleading because only those 5s should have been included in the analysis who met the stringent criterion for hallucination. This paper shows that when one includes in ...

BACKGROUND Sleep paralysis (SP) is characterised by an inability to move voluntarily for a period on going to sleep or on waking. It is also associated with hallucinations, and often with fear. This study seeks to explore the experience of SP in an Irish university sample. METHODS A cross-sectional survey design was employed, with a validated scale for the assessment of SP being distributed t...

In this paper, we study face hallucination which refers to inferring a high-resolution (HR) face image from the input low-resolution (LR) one. We advance an eigentransformation method [1] based on principal component analysis (PCA) for face hallucination by exploring the local geometry structure of data manifold and learning a specified eigentransformation model for each observation image. Firs...
