4.Although qualitative variance among nerve energies was neverrigidly disproved，the doctrine was generally abandoned in favor of theopposing view，namely，that nerve impulses are essentially homogeneous inquality and are transmitted as “common currency” throughout the nervoussystem. Other experiments revealed slight variations in thesize，number，arrangement，and interconnection of the nerve cells，but asfar as psychoneural correlations were concerned，the obvioussimilarities of these sensory fields to each other seemed much moreremarkable than any of the minute differences.
