Abstract:
'Comparison of models of odor interaction' by Cain and his colleagues (1995) is a turning point in assessment of the strengths of smell of mixtures of odorants. Their paper provides the best empirical comparison to date of models of (olfactory) binary mixture intensities and combines this analysis with a cogent critique of the whole tradition of mixture psychophysics. This commentary on their paper argues that their critique is not radical enough.

01:25Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:27Tactile and Chemical Senses
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...
