The publication and presentation of Flor-Henry’s findings from 1969 onwards has triggered an enormous amount of research internationally, on laterality and psychopathology. Flor-Henry’s research has extended his early findings to the study of the patterns of cerebral disorganization in a variety of mental disorders with neuropsychological and quantitative EEG approaches: e.g. in depression, schizophrenia, mania, psychopathy, sexual deviation, hysteria, multiple personality, obsessive compulsive disorder, and, in normal controls (task, age, and gender effects). In addition to his extensive empirical research, he has written, edited, and published a number of books integrating the findings in these areas along with theoretical reviews on the implications of disrupted lateral hemispheric organization in psychiatric conditions.
