The Brain
• Source of thought,
behaviors, and
perceptions
• Composed of billions of
neurons in
interconnected
networks
Brain Anatomy
• 3 Major Parts
Parietal Lobe
Frontal Lobe
– Cerebrum

Frontal lobe
Temporal lobe
Parietal lobe
Occipital lobe
– Brainstem
– Cerebellum

Left vs Right Brain
The Nervous System
Brain Function Integration
• Integration of all brain
functions and
neurological processes
is similar to how multicore computer
processors work.
Diseases of the Nervous System
• In such a complicated system, if any part is
damaged, many problems can occur.
• Neurologists, neurosurgeons, and
neuroscientists study these problems
Stroke
Seizures
Parkinson’s disease
Dementia
Brain Cancer
Spinal Cord Injury
Neurological Injury
• Injury to the nervous system often causes
irreversible damage
– results in disability, sometimes devastating
– occasionally results in very bizarre symptoms
• Neurologists, neurosurgeons, and
neuroscientists are actively studying brain
injury to arrive at new understanding of the
brain and new treatments
– the Brain Computer Interface is one such example
Why study the brain and nervous
system ?
• It’s the control center !
• There are many things even scientists still don’t
know
• Search for better understanding of brain function
and brain repair
• The answer to these problems will rely not only
on the current generation of physicians and
scientists alone, but also on future generations to
come
