PSYB57H3 Lecture Notes - Lecture 2: Golgi'S Method, Camillo Golgi, Nerve Net
Document Summary
Neurons: communication and representation: neurons: cells that are the building blocks and transmission lines of the nervous system create and transmit information about what we experience and know. During that period could not resolve small details, and without these details, the nerve net appeared to be continuous. Used two techniques to investigate the nature of the nerve net: golgi stain: Golgi stain affects less than 1 percent of the neurons, made it possible for cajal to clearly see that the nerve new was not continuous, but was instead made up of individual units connected together. Recording electrode: recording tip is located inside the neuron. When the pressure was increased: same, the rate of nerve firing (number of action potentials that traveled down the axon per second) increased. Makes it possible for the signal to be transmitted across the gap that separates the end of the axon from the dendrite or cell body of another neuron.
