Symptomatology and Therapy of Toxicological Emergencies

There is an interesting introduction by M. A. B. Brazier on the work of Caton and Beck who independently discovered steady potentials in the brain. The excerpts selected and translated from Beck's thesis make informative reading. The reports of recent work deal with correlations between steady potentials and chemical environment (McIlwain, Leao, Grafstein), steady potentials and behavior (Morrell, Rowland, Caspers), steady potentials and seizure activity (Goldring, Bates). Slow impedances changes in relation to behavior are also included (Adey). The discussions in accord with the prevailing custom are often short presentations of the discussant's recent experiments. The interruptions to the various presentations are often points well taken, and are not marred by the wool gathering to which this form of symposium is particularly susceptible. In fine, this symposium is a useful collection of recent research in the area of steady potentials in the brain, an area which is not well represented by recent reviews or by similar symposia.
