Electric convulsion therapy apparatus.

Memory studies in electric convulsion therapy.

The disturbances of memory immediately following electric convulsion therapy (E.C.T.) have been the subject of many investigations (Zubin and Barrera, 1941; Mayer-Gross, 1943; Liberson and Wilcox, 1945; Kalinowsky and Hoch, 1947). Implicit, ifnot explicit, in the majority of these papers is the assumption that memory can be studied in isolation, Bartlett, however, (1932), long ago demonstrated ...

Convulsion Therapy in Schizophrenia

Effect of electric convulsion therapy on urinary excretion of 3', 5' cyclic adenosine monophosphate.

Electric convulsion therapy (E.C.T.) was used in the treatment of 13 women inpatients suffering from depressive symptoms. Twelve of the patients showed a significant increase in urinary excretion of 3', 5' cyclic adenosine monophosphate (cAMP) on the day of treatment, whereas four controls who received all or part of the preliminary treatment but no electric shock showed a reduction. The result...

ELECTRIC IMPEDANCE OF ASTERIAS EGGS Apparatus

Several years ago the absolute value of the al ternat ing current impedance of suspensions of Arbacia eggs was measured at frequencies from 1 to 15,000 kc. (Cole, 1928b). I t was concluded tha t the egg membrane capaci ty was not as near ly a static capaci ty as the capaci ty of the red blood cell membrane (Fricke, 1925 a, 1933), bu t was of the polarization impedance type, similar to tha t whi...

Catecholamine and cardiovascular response to electro-convulsion therapy in man.

Fourteen anaesthetized patients undergoing electro-convulsion therapy on one or more occasions were studied. Systolic and diastolic blood pressure, heart rate, and plasma adrenaline and noradrenaline levels were measured before, during and after the electric shock. With the electric shock, blood pressure and heart rate rose and adrenaline and noradrenaline levels in plasma increased steeply. Th...
