Functional and Neurochemical Asymmetry in the Corpus Striatum
Although it is well documented that the human brain is asymmetric with regard to a variety of functions, most of these functions, notably language and affect, have been ascribed to the cortex. There has been relatively little interest, and consequently relatively little data, bearing on the issue of subcortical asymmetry. However, asymmetry in one subcortical structure, the corpus striatum, has been investigated extensively in rats, and recently to some extent in humans. Our overall understanding of the corpus striatum, in terms of its anatomy, neurochemistry and functions, is certainly considerable vis-a-vis our understanding of the cortex and other portions of the neuraxis. Study of the corpus striatum may therefore elucidate basic mechanisms involved in laterally organized neural systems.
