BRAIN SCANNING TECHNIQUES

ELECTROENCEPHALOGRAPHY

• Used to show brain activity in certain states
• To measure brain activity, metal electrodes
• are placed on the scalp. Each electrode
• or lead makes a recording.

POSITRON EMMISION TOMOGRAPHY

• AKA (PET)
• Shows brain processes.
• Using the sugar glucose in
• the brain to illustrate where
• neuron firing is taking place.

MAGNETIC RESONANCE IMAGING

• The most advanced and helpful
• invention in the brain physiology.
• An MRI uses strong magnetic feilds
• to align spinning atomic nuclei within
• body tissues.

(MRI) CONT.

• Then disturbs the axis of
• rotation of these nuclei and
• observes the radio frequency
• signal generated as the nuclei
• return to their baseline status.

FOUR NEW WORDS

• Neuroimaging
• Conductivity
• Magnetic fields
• Frequency

CONDUCTIVITY

• The degree to which a
• specified material conducts
• electricity.

FREQUENCY

• the number of occurrences
• of a repeating event per u it
• time.

MAGNETIC FEILD

• A condition in the space
• around a magnet or electric
• current in which there is a
• detectible magnetic force and
• two magnetic poles are present

NEUROIMAGINING

• The process of producing
• images of the structure or
• activity of the brain or other
• part of the nervous system.

TWO INTERESTING FACTS

• MRI is the most advanced and helpful invention in the brain psysiology.
• Four of the most common types of brain scanes include the EEG, PET, MRI, and the fMRI.

WHY IS BRAIN SCANNING TECHNIQUES PART OF PSYCHOLOGY?

• Brain scanning techniques is
• Important to psychology because
• The brain scaning techniques help
• Us better understand the structure
• of the brain.

¿TWO QUESTIONS?

• Is the MRI the most advanced
• and helpful invention to brain
• physiology? (T/F)

TRUE

QUESTION 2

• How do humans scan
• brain activity?

EEG, PET, MRI, AND FMRI
