The structure of the Brain
Hector Tirado
The corpus callosum is a
bundle of axons which
connects these two
hemispheres.
The limbic system, often
referred to as the "emotional
brain", is found buried within
the cerebrum. Like the
cerebellum, evolutionarily the
structure is rather old.

•
Frontal Lobe- associated with
reasoning, planning, parts of speech,
movement, emotions, and problem
solving
Parietal Lobe- associated with
movement, orientation, recognition,
perception of stimuli
Occipital Lobe- associated with
visual processing
•
Temporal Lobe- associated with
perception and recognition of
auditory stimuli, memory, and
speech

Central Nervous System
• Consist of the brain and
vertebrates and the spinal
cord.
Peripheral Nervous System
• Voluntary Nervous System
and Autonomic Nervous
System.
• The spinal cord is like a jellylike bundle of
nerve fibers, lies inside the spine.
• The spinal cord acts as a central
communication conduit between the brain
and the rest of the body.
• Millions of nerve fibers within the cord carry
motor information from the brain to the
muscles and other convey sensory
information.
• As part of the voluntary nervous system neurons
of the motor system carry signals to the skeletal
muscles, mainly in response to external stimuli (
voluntary ).
• The autonomic nervous system regulates internal
environment by controlling smooth and cardiac
muscles and the organs and glands of the
digestive, cardiovascular, excretory and the
endocrine systems ( involuntary ).
The Digital Brain Library

“The Brain observatory at the
University of California”
• Jacopo Annese is looking for 1,000 brains. The
director of the brain library is on a quest to
collect, dissect, and digitize images of the
human brain for the Digital Brain Library,
which was launched with support from the
National Science Foundation. (science360.gov)
Annese and his team look for connections,
mapping brain structure and connecting it to human
behavior. He believes that with a large enough catalog
of brains preserved as virtual models, scientists can
explore the organ in ways unheard of, revealing new
insights into what makes the brain tick.
