How do we study brain/behavior relationships?
PET scans◦ rCBF – regional cerebral blood flow
Premise – more blood flow means more (neuronal) activity
Ways to look at function
PET scans◦ rCBF
◦ 2DG – 2 deoxyglucose Premise – need for more sugar – need for more
energy – more (neuronal) activity
Ways to look at function
Histological analysis
Lesion studies ◦ Rationale – if an area is damaged and behavior
changes….. the neurons in that area play a role?
More Invasive methodology
Electrical stimulation
◦ Rationale: if we stimulate an area and we produce or stop a particular behavior….the neurons in that region are important for that behavior
