Processing steps were conducted as introduced in hemispheric asymmetry

Thus, a behavioral manifestation of the hemispheric asymmetry
of these two processes might be revealed.
The findings from this study support our hypothesis that hemispheric asymmetry
of the auditory cortex is associated with asymmetry in the content of cortical metabolites and that this asymmetry in the content of cortical metabolites is affected by age.
When we compared performance on our behavioral measures of attention between those participants reporting attentional problems versus those not reporting such problems, we found an interesting hemispheric asymmetry
. Participants reporting attention problems performed significantly worse in the LVF than participants not reporting attention problems, suggesting an RH attention deficit (Figure 4).
A study with dogs reported hemispheric asymmetry
of electrical activity in the hippocampus (10).
for global and local processing: Language is less important than one might think.
Initially we analysed the data to derive the hemispheric asymmetry
of left (L), right (R), anterior (A) and posterior (P) hemisphere.
The hypotheses were partially supported, in that the time pressure condition produced significantly RH shifted, log-transformed EEG alpha power and hemispheric asymmetry
scores (right alpha power--left alpha power), consistent with negative affect.
Spinelli and Mecacci (1990) provided information linking hemispheric asymmetry
and pattern reversal visual-evoked potentials.
A number of electrophysiological and functional-imaging studies of the brains of healthy, normal perceivers have provided converging evidence for this hemispheric asymmetry
in the strength of response to global and local information.
Co-author Michael O'Boyle of Melbourne University said: "This may be the by-product of a brain organised differently to the usual left/right hemispheric asymmetry
Still, the idea that dyslexia had an anatomical basis in anomalous hemispheric asymmetry
spread quickly, and is still one of the best known behavior-anatomy correlations in the human.
: What's right and what's left.
This supports Annett's (1985) speculation that the rs+ gene operates to the cost of right hemisphere function, and is also consistent with anatomical evidence that hemispheric asymmetry
is achieved by a pruning of cells in the right hemisphere during growth (Galaburda et al., 1987).
