    Notes: Summary Shuttle avoidance training decreased the cAMP content of rat brain (excluding hippocampus and caudate nucleus), amygdala and hypothalamus. Stimulation by tones alone had a similar effect, but only in the brain fraction. Pseudoconditioning or footshocks alone had no effect.

    Notes: Summary Efferent and afferent connections of the visually responsive cortex (area anteromedial, AM) located in the anterior portion of area 18b were studied with degeneration and horseradish peroxidase (HRP) methods following small lesions and HRP injections into this area. Degenerating axons, terminals and retrogradely HRP-labeled neurons were observed in a broad region of the cortex including areas located lateral, medial and anterior to the striate cortex. The main finding of this study is that connections of area AM with area 18a are distributed in discrete patches whose arrangement is similar to that of the lateral extrastriate visual areas postulated in previous physiological and anatomical reports. These results thus suggest that visual area AM is reciprocally connected with visual areas in area 18a. Area AM is also connected with other regions within area 18b, thus supporting the notion advanced by recent studies that area 18b contains more than one visual area. A weak afferent connection to area AM from the dorsal lateral geniculate nucleus of the thalamus was noted. Previously described connections of area 18b with areas 8 and 29 as well as with the lateral and latero-posterior thalamic nuclei were confirmed in the present study.

    Element distribution of some soils of continental Chile and the Antarctic peninsula. Projection to atmospheric pollution (1991)

    Notes: Abstract The elemental content of some soils of continental Chile and the Antarctic Peninsula are reported. The elements: Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd and Pb were analyzed. Trace elements differed among soils. The values for Cd are greater than those reported elsewhere. The organic matter content was observed to have a great importance in the Antarctic Peninsula soils. Differences between local element contents and the mean concentrations values for the terrestrial crust were found. In order to get a better determination of the origin of the aerosol the enrichment factor, used as a criterion to establish the origin of the trace elements in the atmospheric aerosols, should be recalculated based on the local soil.
