Describe Santiago Ramon y Cajal's Neuron Theory. | Nerve cells are independent, separated by a narrow gap. Communication happens via chemicals traversing the gap. |
Charles Scott Sherrington's evidence for Neuron Theory | ~Damage from lesions ~Speed of neural impulse measured by Helmholtz' device |
Who coined the terms "neuron" and "synapse"? | Charles Scott Sherrington |
Explain what some of the major developments in early neuroscience are. | ~Recognition of the mind-body connection ~Developments in localization of function ~Greater understanding of nervous system |
