Document Summary
Familiarize yourself with the terminology of the neuraxis. Special techniques exist for studying the structure and function of the brain. Brain injury links brain anatomy with behavioural deficits. Targeted electrical stimulation can also provide insight on brain function. Single cell stimulation helped map behaviour to specific brain regions: done through probing with electric shock, wilder penfield. Single cell recording reveals the function of individual neurons. Large-scale brain structures are studied using neuroimaging techniques: structural and functional. Structural neuroimaging: ct scans produce structural slices of the brain. Often helpful to diagnose brain injuries: mris provide higher resolution images of the brain. Functional neuroimaging: pet scans display the functional role of brain structures. Needs radioactive tracer: fmri is a less invasive functional neuroimaging technique. Provides temporally imprecise mapping of brain function. Not the best method: eegs display the activity from specific populations. Interpreting neuroimaging data can be challenging and ambiguous: techniques do not show the whole experience.
