PSYC 1100 Section 1.3 Methods For Studying Relation Between Psychological and Nervous System

  1. Lesion Method
    • study effects of tissue damage
    • - clinical
    • - experimental
  2. Recording Methods
    • Electrical recording:
    • - EEG (electroencephalograph), records fluctuations in electrical activity, useful for sleep and epilepsy¬†
    • research
    • - evoked potential (or ERP), an EEG response evoked by a stimulus
    • -¬†single neuron recording, records action potentials from individual neurons: planted in nuclei of the same function
    • Chemical recording:
    • -¬†microdialysis
    • - sampling of cerebrospinal fluid (CSF)
  3. Drugs
    • study how drugs, which cause neurochemical changes, affect behavior
    • alter neurotransmitter by synthesis
    • block storage of a transmitter
    • stimulate of reduce release
    • stimulate or block receptors
    • block enzymatic breakdown or uptake of neurotransmitters
    • - ex. dopamine antagonists (antipsychotics) treat schizophrenia
  4. Imaging methods
    • CT or CAT (computerized tomography); brain structure
    • sMRI (structure magnetic resonance imaging); brain structure (finer image than CT)
    • fMRI (function magnetic resonance imaging); flow of oxygenated blood
    • PET (positron emission tomography); e.g. glucose-related metabolic activity
    • cerebral blood flow (xenon gas)
