SOME NEW TRENDS IN THE STUDY OF THE CORPUS-CALLOSUM

In recent years the corpus callosum has provided a model for the study of cortical connections in the adult and developing brain. In particu lar, aspects of development originally described in the corpus callosu m could be generalized to other cortical connections. New frontiers in clude the analysis of the human corpus callosum, studies of callosal c onnections at the cellular lever and the analysis of dynamic interacti ons between the hemispheres. Gross morphological parameters of the hum an corpus callosum have been measured and related to gender, handednes s etc. The detailed dendritic and axonal morphology of individual call osal neurons and their development is being defined. Electrophysiologi cal investigations and computer simulations are stressing temporal asp ects of the interactions between the hemispheres.
