Document Summary

Efferent information from the brain to the motor effectors is carried in the ventral part of the cord: johannes muller discovered the law of specific nerve energies; each sensory nerve carrie only one kind of sensory information, **presumed that the discoveries on cortical localization and nerve specificity added to evidence in support of the scientific validity of phrenology. Phrenology was correct about certain areas of the brain having specific functions, but they were wrong about which areas did what and they were wrong about the possibility of measuring brain growth from the surface of the skull: hermann von helmholtz found that neural conductance was not instantaneous and nerve conductance was clearly measurable; also measure speed of mental processes.
