Chapter 2.1 Flashcards
Early Invasive Techniques
Methods such as deficit studies, lesioning, ablation, and electrical stimulation used to study brain function.
Deficit Studies
Observing changes in behavior due to brain damage or injury.
Lesioning
Deliberate damage to a specific brain area to study its effects on behavior.
Ablation
Surgical removal of brain tissue to study its impact on function.
Electrical Stimulation (ESB)
Using electrical currents to stimulate neural firing in the brain.
Dr. Wilder Penfield
A neurosurgeon known for mapping brain functions using electrical stimulation.
Electroencephalography (EEG)
Measures brain wave activity through electrical signals in neurons.
CT Scan (Computer-Assisted Tomography)
Uses X-rays to create detailed images of the brain’s structure.
PET Scan (Positron Emission Tomography)
Measures brain activity by detecting radioactive glucose metabolism.
MRI (Magnetic Resonance Imaging)
Uses magnetic fields and radio waves to produce detailed images of brain structures
fMRI (Functional Magnetic Resonance Imaging)
Tracks blood flow in the brain to show real-time neural activity
