What evidence led Lashley to draw his conclusions of equipotentiality and mass action? a. Learning depends on changes at synapses using all types of neurotransmitters. b. Electrical stimulation of the brain can produce either reward or punishment, depending on the intensity of stimulation. c. EEG studies show activation throughout the brain during an experiment on learning. d. Impairment of learning depended on the amount of cortical damage rather than the location.
