AUTHOR=Keller Andreas TITLE=Attention and Olfactory Consciousness JOURNAL=Frontiers in Psychology VOLUME=2 YEAR=2011 URL=https://www.frontiersin.org/articles/10.3389/fpsyg.2011.00380 DOI=10.3389/fpsyg.2011.00380 ISSN=1664-1078 ABSTRACT=Understanding the relation between attention and consciousness is an important part of our understanding of consciousness. Attention, unlike consciousness, can be systematically manipulated in psychophysical experiments and a law-like relation between attention and consciousness is waiting to be discovered. Most attempts to discover the nature of this relation are focused on a special type of attention: spatial visual attention. In this review I want to introduce another type of attention to the discussion: attention to the olfactory modality. I will first clarify the position of attention to smells in a general taxonomy of attention. I will then review the mechanisms and neuroanatomy of attention and consciousness in the olfactory system before using the newly introduced system to provide evidence that attention is necessary for consciousness.
