The Brain

• Source of thought, behaviors, and perceptions
• Composed of billions of neurons in interconnected
  networks

4
Brain Anatomy
Parietal Lobe
Frontal Lobe

• 3 Major Parts
• Cerebrum
• Frontal lobe
• Temporal lobe
• Parietal lobe
• Occipital lobe
• Brainstem
• Cerebellum

The Nervous System
8
Brain Function Integration

• Integration of all brain functions and
  neurological processes is similar to how
  multi-core computer processors work.

9
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
12
Parkinsons disease
13
Dementia
14
Brain Cancer

Spinal Cord Injury
16
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

17
Why study the brain and nervous system ?

• Its the control center !
• There are many things even scientists still dont
  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
