: Chronic Traumatic Encephalopathy (CTE) has received significant media coverage as a major health concern for collision sport athletes and combat veterans. This survey study investigated neuropsychologists' perspectives of CTE. Neuropsychologists ( = 325) were contacted electronic advertisement posted to popular neuropsychology professional listservs and completed a survey regarding their perspectives of: the proposed sequelae of repeated concussions, the strength of the CTE research base, and its media coverage.

Objectives: This paper examines if ratio scaling, the principle behind the psychophysical Power Law, is similarly performed by the left and right cerebral hemispheres and how magnitude estimates derived in each hemisphere are integrated.
Method: Three models of hemispheric integration were tested (dominance, summation, and inhibition) using a cross-modal matching procedure in right-handed, male subjects. Visual stimuli were presented to one or both hemispheres using a tachistoscopic method to test each model.
Article Synopsis
- The study aimed to investigate how stroke-induced lesions in the left or right hemisphere of the brain affect sensory detection thresholds and just noticeable differences across various sensory modalities in comparison to healthy individuals.
- Researchers analyzed three groups: those with right hemisphere lesions, left hemisphere lesions, and age-matched controls, using various methods to assess sensory thresholds and brain lesions through MRI software.
- Results indicated that right hemisphere lesion patients exhibited a higher percentage of sensory impairment compared to controls and left hemisphere lesion patients, with a notable correlation between lesion volume, stroke severity, and sensory threshold impairment, highlighting the interconnectedness of these factors and their impact on functional independence.
