Observations on sensation

Studies in sensation: observations on the localization of the sensations of touch and prick.

The sensory experience commonly referred to as a prick is of great interest, not because of its intrinsic importance, but because of the information about sensory mechanisms which can be obtained from its study. In this paper observations on the ability to localize the sensation of prick are reported and compared with the power of touch localization. The elicitation of the sensation of prick by...

Galen on the elements of olfactory sensation.

In different sources for the Galenic doetrine of smell there appear different elements in the nature of the sense of smell. What we shall suggest is that these accounts are as likely to vary because of varying emphasis as because of error in the copying of manuscripts. In the surviving works of Galen (AD 129 ?-I99) mention of the sense of smell and its objeets can be found in four places: (I) D...

Some Observations on Dirac Measure-Preserving Transformations and their Results

Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measure-preserving transformations between two Dirac measure spaces or a Dirac measure space and a probability measure space. Also, it studies isomorphic Dirac measure spaces, equivalence Dirac measure algebras, and conjugate of Dirac measure spaces. The equivalence classes of a Dirac ...

Effects of epidural anesthesia on thermal sensation.

BACKGROUND AND OBJECTIVES Epidural anesthesia decreases the core temperatures triggering vasoconstriction and shivering, presumably by increasing apparent (as opposed to actual) lower-body temperature. We therefore tested the hypothesis that epidural anesthesia also increases the overall perception of warmth. METHODS We studied 8 volunteers in a randomized, cross-over protocol separated by at...
