PSYC 304 Chapter Notes - Chapter 5: Neuroglia, Transcranial Magnetic Stimulation, Apoptosis
Document Summary
3-dimensional atlas from anterior to posterior of brain. Lesions are survivaldle or terminal; implant or not. Uses a suction device for removal of a piece of brain (typically a piece of cortex) Uses a electrode to burn a piece of brain. To severe communication between parts of brain typically through cutting fibres. Can be temporary, then resume normal brain function. Implant a tube somewhere in the brain that allows drugs to pass through which will turn off said brain structure temporarily. If done repeatedly, there may be an accumulation of glial cells at site of injection reason and effects unknown. Ionotropic glutamate receptor: ampa, kainate, nmda (they induce apoptosis) Bilateral lesions are uncommon and we don"t want that for obvious reasons. Using a high-intensity magnetic field to hyper-stimulate a certain area to induce temporary lesion. Distal damage/spread of damage(transneuronal degeneration): lead to a chain effect of apoptosis. Lesions could have a potential effect on glial cells.
