Left parietal activation related to planning, executing and suppressing praxis hand movements.
OBJECTIVE We sought to investigate the activity of bilateral parietal and premotor areas during a Go/No Go paradigm involving praxis movements of the dominant hand. METHODS A sentence was presented which instructed subjects on what movement to make (S1; for example, "Show me how to use a hammer."). After an 8-s delay, "Go" or "No Go" (S2) was presented. If Go, they were instructed to make the...
متن کاملHand Function Related to Age and Sex
Objectives: The purpose of this study was for evaluation of relationship between hand function and age, sex by Jebson Taylor Test.This study determined whether age might be a factor when associated with sex. Methods: In this study Jebson Taylor was evaluated on hand in 180 normal males and females (0.50% male, 0.50% female) in each of the following 7 subtest in 3 age groups: (15-25), (35-45)...
متن کاملEye-dominance, writing hand, and throwing hand.
Handedness and eye-dominance are undoubtedly associated statistically, although a previous meta-analysis has found that the precise relationship is difficult to explain, with about 35% of right-handers and 57% of left-handers being left eye dominant. Of particular difficulty to genetic or other models is that the proportions are distributed asymmetrically around 50%. The present study asked whe...
متن کاملHand Dominance and Common Hand Conditions.
The goals of this study were to (1) assess how frequently patients present for evaluation of common hand disorders in relation to hand dominance and (2) evaluate the effect of hand dominance on function in patients with these conditions. The authors hypothesized that (1) the majority of patients who seek evaluation would have a condition that affects the dominant hand, and (2) disability scores...
متن کاملLeft Hand Dominance Affects Supra-Second Time Processing
Previous studies exploring specific brain functions of left- and right-handed subjects have shown variances in spatial and motor abilities that might be explained according to consistent structural and functional differences. Given the role of both spatial and motor information in the processing of temporal intervals, we designed a study aimed at investigating timing abilities in left-handed su...
