All Flashcards
How are EEGs used in real-world applications?
Studying sleep patterns, seizures, and overall brain activity.
How are PET scans used in medical diagnosis?
To identify areas of high metabolic activity, such as tumors or areas affected by Alzheimer's disease.
How can lesioning be applied in medical treatments?
In some cases, lesioning is used to treat severe epilepsy by destroying the brain tissue causing seizures.
How is fMRI used in cognitive research?
To identify brain areas involved in specific cognitive processes like memory, language, and decision-making.
How are case studies applied in clinical psychology?
To understand and treat rare psychological disorders or unique patient cases.
How can brain stimulation be used therapeutically?
Transcranial Magnetic Stimulation (TMS) can be used to treat depression by stimulating specific brain areas.
How is CT scanning used after a head injury?
To quickly identify any structural damage like fractures, bleeding, or swelling in the brain.
How is MRI used in diagnosing multiple sclerosis?
To detect lesions or plaques in the brain and spinal cord, which are characteristic of MS.
How are split-brain studies applied to understanding consciousness?
By revealing how each hemisphere can function independently, providing insights into the neural basis of consciousness.
How is EEG used in sleep studies?
To monitor brain wave patterns during different stages of sleep, helping to diagnose sleep disorders.
What is the effect of damage to the frontal lobe?
Can lead to changes in personality, behavior, and decision-making abilities.
What is the effect of severing the corpus callosum?
Prevents communication between the two hemispheres, leading to independent functioning of each side of the brain.
What is the effect of stimulating the motor cortex?
Can cause a person to move a limb or other body part.
What is the effect of increased glucose uptake in a PET scan?
Indicates higher neuronal activity in that brain region.
What is the effect of a tumor on a CT scan?
The tumor appears as an abnormal mass or density within the brain structure.
What is the effect of changes in blood flow on an fMRI?
Indicates the brain areas that are active during a specific task or cognitive process.
What is the effect of sleep deprivation on EEG readings?
Can show slower brain wave activity and increased theta waves.
What is the effect of a stroke on brain function?
Can cause loss of function in areas controlled by the damaged brain region, such as speech or motor skills.
What is the effect of anxiety on brain activity?
Can lead to increased activity in the amygdala and prefrontal cortex, as shown by fMRI.
What is the effect of meditation on brain activity?
Can lead to increased alpha and theta wave activity, as shown by EEG.
What is the significance of Phineas Gage's case?
Provided insights into the role of the frontal lobe in personality and behavior.
What did Roger Sperry's research reveal about the brain?
Advanced our understanding of hemispheric specialization through split-brain studies.
Why is understanding the brain crucial?
Because it's the control center for everything we do, think, and feel.
What does the left hemisphere specialize in?
Language, logic, linear thinking, math, and analytical thinking; controls the right side of the body.
What does the right hemisphere specialize in?
Visual-spatial processing, music, art, emotional processing; controls the left side of the body.
What information does a CT scan provide?
Detailed images of the brain's structure, useful for identifying tumors or injuries.
What information does an fMRI provide?
Measures blood flow changes to show which brain areas are active during specific tasks, combining structure and function.
Why are case studies useful?
Particularly useful when studying rare or unusual phenomena.
What is the main purpose of lesioning?
To understand the function of a specific brain area by observing the resulting behavioral changes after its destruction.
What is the purpose of brain stimulation?
To activate specific brain areas to observe the responses, helping to understand their function.
