2.4: Neuroimaging: Looking at the Brain “Describe the four ways of understanding the human brain” Four basic areas for discussing brain function: a) Structural measures looking at physical aspects of brain b) Electrical measures connecting neurons making neural communication possible c) Processing measures that assess changes in metabolic processing (ex: blood flow as a consequence of different types of thinking) d) Other measures in neuroimaging 2.4.1 Structural Measures  Computerized axial technology (CT) scans: machine makes series of x-ray images, computer assembles images so that various “slices” of the brain can be studied – allows for quick assessment of brain structure  Magnetic Resonance Imaging (MRI): machine creates a very long magnetic field, used to look at a distribution of molecules of a certain type o Advantages: makes better/more accurate image of brain and patient is exposed to less x-rays o Cannot be used with certain medical implants b/c of magnetic field response to scanner 2.4.2 Electrical Measures  Single cell recording: placing a microelectrode into the brain to record the activity of a single cell  Electroencephalogram (EEG)  Event-related potentials (ERP’s) – “momentary changes in electrical activity of the brain when a particular stimulus is presented to a person”  Transcranial-magnetic stimulation (TMS) – magnetic field produced to disrupt the electrical activity in a particular field of the brain 2.4.3 Metabolical Measures  Positron emission technology (PET) scans: person injected with radioactive isotopes  Functional MRI: (fMRI) 2.4.4 Other methods  Lesioning: limited usefulness, but sometimes reveal secrets of cognitive process o Used w/ only two types of subjects: laboratory animals and patients with medical conditions requiring brain surgery o Site and extent of brain lesion are important guides to figuring out the kind of disruption of behavior that is observed  Direct stimulation: o ‘Pioneered’ by Penfield, famous Canadian neurosurgeon o Patient remained conscious during brain surgery in his technique, with only local anesthetic to prevent scalp pain o Surgeon applies small electrical currents to exposed brain, triggering very small regions, then patient asked to answer questions or report out loud the thoughts and memories entering their awareness o By comparing reports with the different regions that were stimulated, a map of cerebral function. was developing. o Most patients reported “dream-like”quality ideas, occasionally reported memories that seemed distinct – seldom possible to check accuracy of reports o Dream-like nature suggests that they were heavily influenced by reconstructive processes (may have been false memories) o By stimulating different regions of the brain, kinds of knowledge, localization of function, and so on, in different parts of the neocortex were discovered. o Difficulties:  Restricted to clinical settings (i.e., patients needing brain surgery)  Organization of a patient’s brain function may differ substantially from a normal pattern, perhaps because they are epileptic, and epilepsy has noticeable consequences on memory – therefore, limits generalizability of results  Special Populations: o Groups of people whose neurological condition is known to differ in regular ways from some standard o May have known neuro. disease of syndrome (i.e., Alzheimer’s, amnesia causing Korsakoff’s syndrome) o May compare various age groups – keeping in mind that neuro. machinery changes in in regular ways at different ages
