Regional water distribution in the rat brain was obtained autoradiographically by activation analysis. The autoradiogram obtained for the normal rat brain showed high accumulation of water in the areas of sensory-motor cortex, hippocampus, thalamus, and amygdaloid cortex, whereas corpus callosum and internal capsule showed low water contents as expected. The estimated values of water content were 78.6 +/- 4.9 weight % for gray matter, and 73.5 +/- 4.9 weight % for white matter, respectively. The mean values of the water content were consistent with those obtained by a conventional drying-weighing method.
