چکیده
Studies on laterality and their implications for learning have hitherto focussed mostly on the areas of learning disabilities and focal brain damage. Such studies in persons with mental retardation have been carried out lately (Hiscock & Kinsbourne 1987, Geschwind and Galaburda 1985b, Sopet et al 1987) and certain patterns of cerebral specialization have been demonstrated in persons with Down's syndrome (Hartley 1981, Elliot 1985, Elliot et al. 1986).

They propose that a systematic s...
متن کاملOlfactory function in young adolescents with Down's syndrome.
Decreased ability to smell is present in adults with Down's syndrome, many of whom are known to have brain pathology analogous to that seen in Alzheimer's disease. Because olfactory loss is well documented in Alzheimer's disease, the question arises whether young adolescents with Down's syndrome, who have no clear Alzheimer's disease-like neuropathology, also exhibit olfactory dysfunction. To c...
