Document Summary

Without the excitotoxin, the frequency or aspiration o animals with sham lesion serve as a control group: most lesions are permanent. Optogenetics (photo stimulation: uses light to artificially activate cells. Histological methods: allow o location of structures o how structures are connected o. The golgi stain o allows us to visually identify the external structures of neurons. The neuron silhouettes are revealed in great detail but the internal structure of the cells is invisible. The electron microscope: electron microscopy o allows us to see small anatomical structures (e. g. synaptic vesicles and details of cell organelles) using a special electron microscope. Transsynaptic labelling with pseudorabies virus (prv) allows us to trace chains of connected neurons. Functional magnetic resonance imaging (fmri) o the most recent advance in imaging technology o o has four major advantages over other imaging tools. It produces images of the increase in oxygen flow in the blood to active area of the brain.
