Document Summary

Staining: take slice of tissue then fixate it. Question: what regions in the brain are involved in sexual behavior. Fact: stereotaxic lesion vmh no female reproductive behavior. Acute: brain slices, study of live single cells and small network properties, calcium imaging. Culture: study of live single cells ad intracellular mechanisms, can be done for weeks. Using a computer to stimulate single neurons and synapses which builds a computational. Putting models together to build artificial neural networks. Brain-machine interface: restore function through the use of a brain-controlled. Receptor potentials go under sensory processing which leads to you perceiving something. Photons and the electromagnetic spectrum, light is a radiation, a sine wave. Not all eyes are the same, species to species variations. We are only sensitive to a part of the electromagnetic spectrum. Hue is related to frequency of the sine wave. Visual field: the visual space that you sense. Monocular (seen by one eye) vs. binocular (seen by both eyes)
