Thalamus 

• In forebrain 
• Receives sensory info. & sends them to appropriate areas of the forebrain 
• Like a switchboard 
• Covers everything except smell 

Limbic Center 

• Emotional control center of the brain 
• Made up of hypothalamus, amygdala, and hippocampus 

Hypothalamus

• Pea sized in the brain, but plays a big role. 
• Body temperature 
• Hunger
• Thirst
• Sexual Arousal (libido) 

Hippocampus and Amygdala 

• Hippocampus is involved in memory processing.
• Amygdala is vital for our basic emotion.

Cerebral Cortex 

• Top layer of our brain.
• Contains wrinkles called fissures.
• The fissures increase surface area of our brain. 
• Laid out it would be about the size of a large pizza. 

Hemispheres 

• Divided into a left and right hemisphere 
• Contralateral controlled- left controls right side of body and vice versa. 
• Brain Lateralization 
• Lefties are better at spatial and creative tasks.
• Righties are better at logic

Split- brain patients

• Corpus collosum attached the two hemispheres of cerebral cortex 
• When removed you have a split-brain patients
