An FMRI study of the effects of psychostimulants on default-mode processing during Stroop task performance in youths with ADHD.

13 Sep 2009 OBJECTIVE: The authors examined the effect of psychostimulants on brain activity in children and adolescents with ADHD performing the Stroop Color and Word Test. METHOD: The authors acquired 52 functional MRI scans in 16 youths with ADHD who were ... Read more...

Extent of initial injury determines language lateralization in mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS).

8 Sep 2009 PURPOSE: To assess the prevalence and attributes of atypical language lateralization (ALL) in patients with left mesial temporal lobe epilepsy associated with hippocampal sclerosis (MTLE-HS). METHODS: We recruited consecutive patients with left ... Read more...

Hippocampal-dependent spatial memory functions might be lateralized in rats: An approach combining gene expression profiling and reversible inactivation.

30 Aug 2009 The hippocampus is involved in spatial memory processes, as established in a variety of species such as birds and mammals including humans. In humans, some hippocampal-dependent memory functions may be lateralized, the right hippocampus being ... Read more...
