Document Summary

Which areas of the brain are involved in particular behaviours, what neurons are used and the activity of those neurons. The best approach is approaching is using multiple tools to get to your area of interest (converging operations) The process to get the brain possible to visualize is called histology. Perfusion: have to get rid of the blood that feeds into the brain. Use saline, and the animals heart as a pump that will wash out the blood. You cannot visualize anything if you don"t do this step. Fixation: must fix the brain with formalin. Inject formalin that creates cross-links b/w proteins of the brain in order to be able to use it and look at it under microscope. Embedding and slice: in order to see brain under microscope, must harden the brain and slices the microscope into thin slices.
