systematically reviewed evidence of left and right brain asymmetry in electrophysiological (EEG and event-related potential), behavioral (dichotic and visual perceptual asymmetry), and neuroimaging (PET, MRI, and NIRS) and discussed that individual differences in left and right brain function measurements in patients with depression are related to the clinical diagnosis of subtypes of depression, anxiety disorders, and clinical response to antidepressant drugs or cognitive behavioral therapy [16].
(7) Emerging research investigating benefits of auditory training in patients with CAPD, including older adults, demonstrates efficacy of programs that include, for example, dichotic inter-aural intensity difference training that can be administered using customized stimuli through an audiometer.
Perhaps of greater interest, when dichotic listening performance was correlated with a negative symptom from the PANSS interview questionnaire, correlations were all non-significant and close to zero (see right-hand panels of Figure 4).
In this dichotic test, binaural thresholds for a 500 Hz pure tone are determined in the presence of contralateral masking noise.

Subsequently, the continuous CACNA1B ([Ca.sub.v]2.2) protein expression data were converted into dichotic data (low versus high) using specific cutoff values, which were selected to be significant in terms of overall survival (OS) using the X-tile software program (The Rimm Lab at Yale University; http://medicine.yale.edu/lab/rimm/research/software.aspx) [22, 23].
