Document Summary
Lesion method damaging or removing sections of the brain. Do this to see what happens/changes about behavior. Detect electrical activity of neurons in particular regions of brain. Can indicate if there are tumors/ seizures present. Records biochemical changes in brain as they are happening in different locations. Shows picture of what the brain looks like. Radioactive substance injected, lights up wherever brain is most active. Mri uses magnetic field to show picture of soft tissues. Measures relative activity of various brain areas during tasks. Shows what is going on in brain as they are doing something. Controls involuntary behaviors and primitive behaviors under voluntary control. Medulla controls bodily functions that do not have to be consciously willed. Works even when unconcious, what keeps people alive. Pons regulates sleep and arousal; coordinates movements from left and right side of body. Directs incoming information from sense receptors to cerebral cortex. Visual info from eyes to thalamus, from thalamus to occipital lobe.
