Electroencephalogram (EEG) coherence (COH) and power measures were included in a series of stepwise discriminant analyses to determine which variables were most sensitive in the differentiation of four psychiatric inpatient groups and two major classes of psychotropic medication. Eight channels of eyes-closed, bipolar EEG activity were recorded from 74(More)
This study was a preliminary evaluation of biofeedback training of human subjects to control high-frequency EEG responses in the 35- to 45-Hz (40-Hz) and 21- to 31-Hz ranges. A total of 22 adult males divided into three groups were successfully trained for increases or suppression of 40-Hz EEG, or increases of 21- to 31-Hz EEG. Dissociation of rates of(More)
Two groups of eight adults successfully trained with biofeedback for increases in 40-Hz EEG responses in left or right hemispheres also demonstrated significant 40-Hz EEG increases during baseline periods, and increases in the contralateral hemisphere during training periods. No changes in heart rate, 40-Hz EMG, or 21- or 31-Hz beta, alpha, or theta EEG(More)
The material properties of the cornea are important determinants of corneal shape and refractive power. Corneal ectatic diseases, such as keratoconus, are characterized by material property abnormalities, are associated with progressive thinning and distortion of the cornea, and represent a leading indication for corneal transplantation. We describe a(More)
PURPOSE To compare the biological effects of riboflavin-ultraviolet A (UVA) corneal cross-linking (CXL) performed with a traditional epithelium-off method to several transepithelial methods in a rabbit model. Preliminary experiments on biomechanical rigidity were also performed. METHODS Four treatment groups were included: (1) standard epithelium-off, (2)(More)
PURPOSE To noninvasively evaluate the effects of corneal hydration and collagen crosslinking (CXL) on the mechanical behavior of the cornea. SETTING Cleveland Clinic Cole Eye Institute, Cleveland, Ohio, USA. DESIGN Experimental study. METHODS An optical coherence elastography (OCE) technique was used to measure the displacement behavior of 5 pairs of(More)
Studies suggest that standard corneal collagen crosslinking (CXL) is a safe and effective treatment to stiffen the cornea for keratoconus and other ectatic corneal disorders. The purpose of the present study was to compare the biomechanical effects of transepithelial benzalkonium chloride-EDTA (BAC-EDTA) riboflavin-UVA crosslinking to standard(More)
Self-regulation methods incorporating biofeedback are known to be useful in the treatment of psychophysiological disorders in psychologically normal patients. In this study, the effectiveness of Quieting Response (QR) training for the treatment of secondary psychophysiological complaints in psychiatric inpatients was assessed. Ten male and 27 female(More)
