LATERALITY, HEREDITY,

BEHAVIOR, AND EVOLUTION

SUPA PSYCHOLOGY

AGENDA: SEPTEMBER 17TH

• Questions?

• Review brain imaging/which technique?

• Introduction to laterality

• Split-brain studies

• Cerebral hemisphere specialization

• Lateral activity

• Genetics introduction

• Name that Hemisphere Game

NAME THE BEST TECHNIQUE

• I want to learn more about how stroke impacts the motor planning in humans.

• I want to learn more about the areas of the brain that are used to solve math problems.

• I am hoping to monitor the effectiveness of seizure medication in my epileptic patients.

• I want to see what neurotransmitters are affected by a new drug to treat schizophrenia

Are we really symmetric? Look closely.How are the hemispheres the same or different?

LATERALITY ACTIVITY

• Take out a pen and paper
