PSYC 2560 Lecture Notes - Lecture 1: Diffusion Mri, Concussion, In Situ Hybridization
Document Summary
Rendering an area unusable (temporarily or permanently) to determine its purpose. One of many primary research methods used in biopsychology. Stereotaxic atlas: gives coordinates for different brain structures in a number of different species. Bregma: (point zero) used as beginning place on top of skull for taking measurements. Cortical or sub-cortical knife cuts are an old fashioned method where a knife severs ties to specific area to determine function. Cryoprobe: has coolant pumped through, freezes an area of the brain (more ethically sound than cortical cuts) to study behaviour. Intracellular unit recording: recording within a single neuron. Opposite of lesion studies: areas are rendered more active. Extracellular unit recording: looking at the firing of a neuron outside cell. Multiple unit recording: looking at multiple neurons firing. Drugs are administered by: stomach, peritoneal cavity, large muscle, tissue under. Invasive eeg recording: looking at millions of neurons skin, large surface vein, injected directly into brain using cannula.
