In the first half of the 20th century, advances in electronics enabled investigation of the electrical properties of nerve cells, culminating in work by <answer>Alan Hodgkin, Andrew Huxley</answer>, and others on the biophysics of the action potential, and the work of Bernard Katz and others on the electrochemistry of the synapse. These studies complemented the anatomical picture with a conception of the brain as a dynamic entity. Reflecting the new understanding, in 1942 Charles Sherrington visualized the workings of the brain waking from sleep:
Work in the first half the 20th century in electrical properties of nerve cells were by what two main scientists?
