Visual targets can be processed more quickly and reliably when a hand is placed near the target. Both unimodal and bimodal representations of hands are largely lateralized to the contralateral hemisphere, and since each hemisphere demonstrates specialized cognitive processing, it is possible that targets appearing near the left hand may be processed differently than targets appearing near the r...

Recent studies have shown that changes in visual processing in perihand space are limited to the area around the right hand, at least in right-handers. One explanation for these findings is that perception is altered at locations where action is more likely to occur. To test this notion, we asked both right- and left-handers to perform an unspeeded visual discrimination task under four hand-pos...

This paper examines and acknowledges the evolution of left-hand range demands in classical guitar technique since 19th Century. In that regard, after presenting problems which surround main subject investigation, special attention will be given to section dedicated Grand traité instrumentation et orchestration modernes by Hector Berlioz (1844), development music 1850, as well 20th Century conte...

Cardiac myxoma is usually a benign tumor in the left atrium that accounts for more than 50% of primary cardiac tumors. A 55-year-old female referred to our hospital with chest pain, referred pain to the left hand, and severe dyspnea. Transthoracic Doppler Echocardiography was performed and the results showed a large and mobile left atrial mass without any attachment to the interatrial septum. I...
