Drosophila Spidey/Kar Regulates Oenocyte Growth via PI3-Kinase Signaling

Cell growth and proliferation depend upon many different aspects of lipid metabolism. One key signaling pathway that is utilized in many different anabolic contexts involves Phosphatidylinositide 3-kinase (PI3K) and its membrane lipid products, the Phosphatidylinositol (3,4,5)-trisphosphates. It remains unclear, however, which other branches of lipid metabolism interact with the PI3K signaling ...

Somesthetic senses.

This is a review of recent advances in our understanding of the sensory modalities of touch, temperature sensitivity, and pain. Most of the research described is psychophysical or perceptual in nature, but physiological and imaging studies are included when they sharpen issues or reveal underlying mechanisms. Coverage of touch research comprises the subjects of acuity, vibrotaction and texture ...

Multiplying Senses

My aim is to motivate and develop a view of what senses are. Senses, as I conceive of them, avoid a number of the problems that plague a broadly Fregean approach to the semantics of belief ascriptions, as I hope to show. The chief innovation of my view that enables these solutions is that beliefs are taken to have multiple, truth-conditionally equivalent contents. In traditional Fregean termino...

Chemical senses.

In the last decade, studies using approaches from molecular biology have substantially advanced our understanding of the early events in olfaction and taste. The many odorants that we can recognize may well interact with many distinct receptor proteins. Of the four taste qualities that we recognize, studies on salty and sour suggest that these tastes involve ion channels in the membrane of rece...
