Intro to Psychology module 7 – methods 4 studying brain

cadavers
dead bodies

lesions
brain damage as a result of strokes, falls, automobile accidents, gunshots, or tumors.

Until recently, the brain was difficult to study because __________________.
Nonintrusive imaging techniques to get a good picture of structures & activities in the brain didn’t exist

In the past, the most immediate approach in visualizing and understanding the structure of the brain was to analyze _______________.
brains of human cadavers

An advantage of studying the brains of human cadavers is that _________ of the brain can be fully studied and a disadvantage is the brain is _________.
structures; dead

Lesion studies are used to study the ______________________.
Damaged part of a brain to determine its functioning ability

An advantage of lesion studies is that _________________.
Loss of brain function can be observed

The significance of the lesion study of Phineas Gage’s damaged brain is that it provided evidence that __________________.
The frontal lobe is involved in controlling personality traits, emotion, inhibitory control and goal-setting abilities

single-unit recording method,
hin microelectrode is surgically inserted in or near an individual neuron, is used primarily with animals.

electroencephalograph (EEG).
an instrument that records the electrical activity produced by the brain’s neurons through the use of electrodes placed on the surface of the research participant’s head

positron emission tomography (PET) scan
an invasive imaging technique that provides color-coded images of brain activity by tracking the brain’s use of a radioactively tagged compound, such as glucose, oxygen, or a drug that has been injected into a person’s bloodstream

Functional magnetic resonance imaging (fMRI)
a type of brain scan that uses a magnetic field to create images of brain activity in each brain area.

A noninvasive neuroimaging technique that produces very clear and detailed images of the structures and activities in the brain in response to magnetic fields is called _________________.
functional MRI

An invasive imaging technique that provides color-coded images of brain activity by tracking the brain’s use of a radioactively tagged compound, such as glucose, oxygen, or a drug, is called ——–
positron emission tomography (pet)

A thin probe is implanted in the brain to study the response of a specific neuron. Viewing the brain using this technique is called _______________.
single-unit microelectrode

A technique that records the electrical activity produced by the brain’s neurons through the use of electrodes placed on the surface of the head is called _____________.
electroencephalography (eeg)

transcranial magnetic stimulation (TMS
a procedure in which magnetic pulses are applied to the brain of living persons with the goal of temporarily and safely deactivating a small brain region.

Transcranial magnetic stimulation (TMS) is a useful technique that _________________.
Uses magnetic pulses to areas of the brain to relieve symptons of Parkinson’s disease
