Animal Senses

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...

The improvement of sight was considerable. An interesting point in one case was that the urine was free from albumen until after the onset of the neuritis. Dr. Adam...
