Term | Definition |
---|---|
Ablation | Removal of a brain area, generally with a surgical knife |
Computerized Axial Tomography (CT and CAT scan) | Method of visualizing a living brain by injecting a dye into the blood and placing a person's head into a CT scanner; x-rays are passed through the head and recorded by detectors on the opposite side |
Evoked Potentials or Evoked Responses | Electrical recordings on the scalp from brain activity in response to a stimulus |
Functional Magnetic Resonance Imaging (fMRI) | A modified version of MRI that measures energies based on hemoglobin instead of water; determines the brain areas receiving the greatest supply of blood and using the most oxygen |
Lesion | Damage to a structure |
Magnetic Resonance Imaging (MRI) | Method of imaging a living brain by using magnetic field and a radio frequency field to make atoms with odd atomic weights all rotate in the same direction and then removing those fields and measuring the energy that the atoms release |
Magnetoencephalograph (MEG) | A device that measures the faint magnetic fields generated by brain activity |
Phrenology | A process of relating skull anatomy to behavior |
Positron-Emission Tomography (PET) | Method of mapping activity in a living brain by recording the emission of radioactivity from injected chemicals |
Stereoaxic Instrument | A device for the precise placement of electrodes in the brain |
Transcranial Magnetic Stimulation | The application of an intense magnetic field to a portion of the scalp, temporarily inactivating neurons below the magnet |
