Respond to the following questions
1. Studies of commissurotomy (split-brain) patients have led to certain findings
concerning the nature of consciousness in each of the brain hemispheres. Describe the
research findings that concern the recognition of one’s own face by each hemisphere.
What are the most consistent conclusions of the studies?
2. What categories of the phenomenon of the “alien hand syndrome” are associated
with which types of brain damage?

transfer? A review. Behavioural Brain Research, 223, 211-221.
Respond to 3 of the following questions
1. What are the three main commissures of the brain and which parts of the brain do
they connect?
2. What are the three main subdivisions of the corpus callosum? Which areas in the
two hemispheres does each subdivision connect?
3. Two models have been proposed concerning the role of the corpus callosum for the
communication of the two hemispheres of the brain: the inhibitory model and the
excitatory model. Briefly describe the role of the corpus callosum in each model.
4. When comparing the two models, which functions can be attributed to the
inhibitory function of the corpus callosum and which to the excitatory function?
5. Chose a disorder from the ones mentioned in the article and describe the research
evidence concerning the contribution of the corpus callosum in the disorder.
