Organization and the Biology of
Consciousness Exam with Verified
Detailed Answers
corpus callosum -
correct answer ✅bridge of fibers passing information between the
two cerebral hemispheres
split brain -
correct answer ✅a condition in which the two hemispheres of the
brain are isolated by cutting the connecting fibers (mainly those of
the corpus callosum) between them
cognitive neuroscience -
correct answer ✅the study of relations between brain and
thinking
dual processing -
correct answer ✅we evaluate our environment both consciously
and unconsciously
What did neurosurgeons Vogel and Bogen discover in 1961? How
did they discover it? -
correct answer ✅They discovered that people with split brains can
live normally, with their intellect and personality intact.

Detailed Answers
They discovered it by cutting the corpus callosum to fix major
epileptic seizures, which they suspected to be caused by an
amplification of abnormal brain activity bouncing back and forth
between two cerebral hemispheres.
Explain what we learned from the HEART experiment in 1983 -
correct answer ✅divided consciousness; the left hemisphere
controls the right field of vision, right hemisphere controls left field
of vision
What role does the left hemisphere play in our use of language? -
correct answer ✅has broca's and wernicke's area, so receives info
through wernicke's (being able to understand language) and
expresses info through broca's (aka expression/speaking)
What role does the right hemisphere play in our use of language? -
correct answer ✅Doesn't have much of a role in language, but due
to neural plasticity, victims with damage to the left hemisphere may
develop language in the right hemisphere
