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

Brain Anatomy 3 Major Parts – Cerebrum Frontal lobe Temporal lobe Parietal lobe Occipital lobe – Brainstem – Cerebellum Frontal Lobe Parietal Lobe Temporal Lobe Occipital Lobe Cerebellum Brainstem

Movement Sensation Coordination

Left vs Right Brain

The Nervous System

Brain Function Integration Integration of all brain functions and neurological processes is similar to how multi- core 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
