Lateralization and Specialty Areas

Lateralization of Function n n Although the two cerebral hemispheres cooperate with each other, they do not perform identical functions. Some functions are LATERALIZED – located primarily on one side of the brain

Left Hemisphere n Participates in the analysis (breaking thing down in to pieces) of information q q q Extracts the elements that make up the whole experience. Serial events- elements occur one after the other…the pieces! Think about math class, part to whole- the left hemisphere looks at the parts

Left Hemisphere Talking Reading Writing Logic Number skills

Left Brained Activity n Write down the last thing you ate? n Explain why is this a left brained activity

Right Hemisphere n Specialized for synthesis (putting things together) it is good at putting isolated elements together to perceive things as a whole

Right Hemisphere Read Maps 3 D Construct complex objects Creative Artistic skill

Right Brained Activity Draw a picture of Mr. Cohen. Explain why this is a right brained activity.

Specialty Areas Broca’s Area In the frontal lobes, the Broca’s Area controls language expression, directs the muscle movements involved in speech Wernicke’s area Found in the left temporal lobe, the Wernicke’s Area controls language reception. This area is involved in language comprehension and expression.

Sensory Cortex This cortical area receives information from the skin senses. n Create a correlation between sensitivity and size of the body part.

Primary Motor Cortex Location-Parietal Lobe n n n The motor cortex sends messages out to the body Right hemisphere controls the lefts side of the body and the left hemisphere controls the right side of the body. Create a correlation between body part size and movement based upon this picture

Why has there been so much recent focus on concussions? n What is a concussion?

Phineas Gage Research on Gage lead to a better understanding of the function of the frontal lobe

Prefrontal Cortex Deficits n n n Slowing of thoughts and behaviour Loss of spontaneity Changes in emotional reactions Inappropriateness, jocular, disinhibited. Loss of self-awareness Deficiencies in foresight and planning
