The Uses Of Maya Structures: A Study Of Architecture And Artifact Distribution At Sepulturas, Copan, Honduras, Julia A. Hendon
The Uses Of Maya Structures: A Study Of Architecture And Artifact Distribution At Sepulturas, Copan, Honduras, Julia A. Hendon
Anthropology Faculty Publications
This dissertation presents a compositional analysis of the architecture and a distributional analysis of the associated artifacts resulting from excavation of some ninety buildings dating from the Late to Terminal Classic Period at the Maya site of Copan, Honduras. The study of all artifacts recovered from primary contexts, both in situ and redeposited, focuses first on a determination of their function, second on an analysis of their distribution within the site, and third on their associations with one another in order to identify the kinds of activities carried out at various locations. A second line of evidence used is the …

Sensory Modulation Of Juvenile Play In Rats, Stephen M. Siviy, Jaak Panksepp

A series of experiments was conducted to determine the extent to which somatosensory stimulation is necessary for the elaboration of juvenile play in rats. Anesthetization of the dorsal body surface of juvenile rats with xylocaine reduced the frequency of pinning, an indicator variable for play, by 35% to 70%, while motivation to play, measured by dorsal contacts, an index of play solicitation, remained largely intact. These data suggest that dorsal body surface anesthetization impairs the ability of juvenile rats to perceive and/or respond to playful gestures. When untreated animals were paired with xylocaine-treated animals, the xylocaine-treated animals consistently pinned the …
