This is consistent with previous observations of clinically bradykinetic PD patients who may show normal movement durations when reaching for 3D targets, particularly when full vision is available [40], [41].
If, however, spatial representations are distinct for pitch and numbers, as suggested by Beecham et al. [27], congenital amusics may show normal performance with the number lines, despite their pitch deficit.
Therefore, if patients make a large number of such errors, they may show normal or even hyperfrontal activation during a working memory task in spite of high error rates.
Radiographic evaluation of the affected tooth may show normal morphology of the crown but reduced enamel opacity that may approach that of the dentine.
Since measurement of total protein levels in the CSF may show normal results despite a blood-CSF barrier dysfunction [ 19], the albumin CSF-serum concentration quotient (QAlb) was analysed.
Analysis of total protein in the CSF may show normal results despite a blood-CSF barrier dysfunction, because it does not take into account the serum protein level [ 19].
