Document Summary

Lecture 5 (chapter 5) february 05 2016 biology psyc. Angiogram: x-ray of head with dye present in cerebral blood vessels. Cat/ct (computerized axial tomography: measure of x-ray absorptions at several positions around the head, maps tissue density. Mri (magnetic resonance imaging: gives higher resolution images of brain structures. Such as oxygen use, in active brain areas: to produce images where reasonable temporal resolution (how fast to capture the images, spatial resolution. Mapping which brain areas" activity more active. Based on how quickly the action being metabolized. Optical imaging: uses near-infrared light passed through the skull to reveals brain activity. Can make short distance into the cortex. Meg (magneto encephalography: measures the tiny magnetic fields given off by active neurons, detecting changes in activation. Moment by moments basis temporal resolution. Soon as there"s change, it knows about it: essential for cognitive neuroscience studies. Look at the effects of certain task and activation. Get to know how this lead to this immediately.
