Psychology - Mapping Of The Brain

Front 1

Labeled and photographed cortical tissue during brain surgery as patients reported sensations in each area that was stimulated by an electrode

Back 1

Wilder Penfield

Front 2

Developed in Great Britain in 1972

Back 2

CT

Front 3

Information from x-ray pictures is converted by scanner into a digital code for computer viewing

Back 3

CT

Front 4

Scanning by this method can give sliced views of the brain from many different angles

Back 4

CT

Front 5

A form of scanning that views metabolism in the brain after patient is injected with radioactive sugar

Back 5

PET

Front 6

Information is converted into colors

Back 6

PET

Front 7

Darker colors indicate low sugar use and less brain activity

Back 7

PET

Front 8

Areas of inactivity correspond to such things as brain deterioration or disease

Back 8

PET

Front 9

Based on the principle that a hydrogen atom exposed to a magnetic field will form into a straight line with other hydrogen atoms

Back 9

MRI

Front 10

Hydrogen atoms are altered by radio signals and return to their original position when the signal is turned off

Back 10

MRI

Front 11

When they return to original positions, the hydrogen atoms give off small electrical signals that are interpreted by a computer

Back 11

MRI

Front 12

Color-enhanced images of extreme detail

Back 12

MRI

Front 13

Taken while patient is actively functioning like reading or doing math

Back 13

fMRI

Front 14

Based upon older technology of EEG

Back 14

EEG

Front 15

Uses a computer to determine any degrees of difference in brain functioning between normal people and those with brain dysfunctions

Back 15

EEG

Front 16

Degree of difference is then converted to a color code which indicates departure from normal waves

Back 16

EEG
