History of neuroscience that the functional unit of the brain is the neuron. Golgi and Ramón y Cajal shared the Nobel Prize in Physiology or Medicine in 1906 for their extensive observations, descriptions and categorizations of neurons throughout the brain. The hypotheses of the neuron doctrine were supported by experiments following Galvani's pioneering work in the electrical excitability of muscles and neurons. In the late 19th century, Emil du Bois-Reymond, Johannes Peter Müller, and Hermann von Helmholtz showed neurons were electrically excitable and that their activity predictably affected the electrical state of adjacent neurons. In parallel with this research, work with brain-damaged patients
The Boston process approach the outcomes to make conclusions on what is going on in the brain. These conclusions are based on the errors that occurred during the test. The point of looking at the errors is to see what issues may have occurred when trying to process the information and answer the question in order to evaluate the specific deficit(s). Certain inaccuracies may infer that there’s damage to a definite part of the brain, like speech difficulties implicating the speech area in the left hemisphere. The qualitative analysis focuses on closely observing the process by which a patient arrives at a final answer.
