Document Summary

Bregma: used as a reference point to map out brain locations. Transcranial magnetic stimulation: non-invasive procedure in which a magnetic coil is placed over skull to stimulate brain. Brain electrical activity: measures summations of graded potentials from thousands of neurons, changes as behaviour changes. Event related potentials: complex waveforms related in time to a specific sensory event. To counter the effects of noise, stimulus is presented repeatedly and recorded responses are averaged. Magnetoenvechalogy: magnetic potentials recorded from detectors outside the skull, can see 3d image. Computerized tomography: x-ray beam projected through head of patient to detector ,series of photos at each axis yield a 30 rep. Magnetic response imaging: pass patient by strong magnetic field to produce a 3d static image by measuring the radiation emitted by each hydrogen atom. Functional mri: change in elements such as iron and oxygen measure the performance of a behaviour.
