Bimodal odor processing with a trigeminal component at sub- and suprathreshold levels.

Odors are typically bimodal in nature, interacting with the olfactory and trigeminal systems. The trigeminal component may be noticed (e.g.

Olfactory modulation of affective touch processing - A neurophysiological investigation.

Touch can be highly emotional, and depending on the environment, it can be perceived as pleasant and comforting or disgusting and dangerous. Here, we studied the impact of context on the processing of tactile stimuli using a functional magnetic resonance imaging (fMRI) paradigm. This was achieved by embedding tactile stimulation in a variable olfactory environment.
