NROB60H3 Chapter Notes - Chapter 2: Franz Nissl, Golgi'S Method, Endoplasmic Reticulum
Document Summary
In neuroscience there is no need to separate mind from brain: once we fully understand the individual and concerted actions of brain cells we will understand the origins of our mental abilities. Neurons and glia are two diff. types of cells. Neurons: information processing cell of the nervous system; also called nerve cells: most neurons use ap to send signals, others communicate using synaptic transmission. Sense changes in the environment , communicate these changes to other neurons and command the body"s response to these sensations. Most challenging part of studying brain cell structure is the size since they are about 0. 01- 0. 05 mm in diameter. Neuroscience only developed after compound microscopes in the late 17th century. Brain tissue needs to be hardened (fixed) in formaldehyde and then sliced into thin slices by a microtome before it could be studied. Histology: microscopic study of the structure of tissues.
