It is probable that learning to read depends in part upon the ability to establish an association between a seen object (customarily perceived within the right hemisphere) and a verbal symbol (mediated by the left). It is possible that as the reading skill develops, verbal symbol recognition may also become a left hemisphere function. A complex interaction between the two developing hemispheres is involved. A clue to the nature of this problem is that developmental dyslexia is six times more common in boys than in girls.

The incidence of CNS neoplasms in childhood (2.4/100 000 per annum) ranks second only to leukemia in Manitoba. For both sexes somewhat elevated incidences were noted for both extreme age groups; i.e. 0-4 and 10-14. Such peaks were more prominent for gliomas, which may indicate differential factors operation in the genesis of gliomas between early and late childhood. The former may be related to genetic and/or perinatal environmental factors and the latter, to environmental factors, in early childhood. Excess occurrences of gliomas among Irish, Scottish and Icelandic offsprings were observed, which possibly indicates the importance of either genetic or environmental factors peculiar to these ethnic groups. There was no evidence of time clustering (i.e. season and year) by estimated conception or by birth.
