Question

1. the biopsychosocial approach
2. how do biology and experience influence the brain?

a. neurogenesis:
b. neuroplasticity:

1. studying the brain

type\thow does it work?\twhen would they be used?
lesion
electroencephalograph (eeg)
magnetoencephalography (meg)
positron emission tomography (pet)
magnetic resonance imaging (mri)

Explanation:

Neurogenesis is the creation of new neurons in the brain, influenced by biological factors like genes and hormones, and can be affected by experiences such as learning and exercise. Neuroplasticity is the brain's ability to change its structure and function in response to experience, which can occur through processes like the formation or elimination of synapses.

• Lesion: Works by damaging or destroying a part of the brain to study the resulting changes in behavior and function. Used when researchers want to understand the function of a specific brain - region.
• EEG: Records the electrical activity of the brain via electrodes on the scalp. Used for diagnosing epilepsy, sleep disorders, and brain - death.
• MEG: Detects magnetic fields produced by electrical currents in the brain. Used for mapping brain activity in real - time, especially for localizing the source of epileptic seizures.
• PET: Uses radioactive tracers to visualize and measure changes in metabolic processes in the brain. Used for detecting tumors, Alzheimer's disease, and studying brain function in mental health disorders.
• MRI: Uses a magnetic field and radio waves to create detailed images of the brain's structure. Used for diagnosing brain tumors, strokes, and multiple sclerosis.

Lesion: How it works - Damages brain part to study function changes; When used - To understand specific brain - region function.
EEG: How it works - Records brain's electrical activity via scalp electrodes; When used - For diagnosing epilepsy, sleep disorders, brain - death.
MEG: How it works - Detects magnetic fields from brain's electrical currents; When used - For real - time brain activity mapping, localizing seizure sources.
PET: How it works - Uses radioactive tracers to visualize metabolic processes; When used - For detecting tumors, Alzheimer's, studying mental health brain function.
MRI: How it works - Uses magnetic field and radio waves for brain structure imaging; When used - For diagnosing brain tumors, strokes, multiple sclerosis.
