Attentional modulation in human primary olfactory cortex
Nature Neuroscience, 2004Central to the concept of attention is the fact that identical stimuli can be processed in different ways. In olfaction, attention may designate the identical flow of air through the nose as either respiration or olfactory exploration. Here we have used functional magnetic resonance imaging (fMRI) to probe this attentional mechanism in primary ...

Olfaction: From Odorant Molecules to the Olfactory Cortex
Physiology, 2004How do we smell? Our knowledge of how odor information from the environment is perceived has greatly advanced since the discovery of ~1,000 genes for odorant receptors in the mammalian genome. From the combination of molecular-genetic, electrophysiological, and optical imaging studies a better understanding of how we smell is emerging.

Analysis of the Lynch-Granger model for olfactory cortex
Biological Cybernetics, 1989The behavior of the Lynch-Granger model for layer-II piriform cortex is reviewed, and a simple neural model with similar properties is introduced. This model allows us to understand the observed functionality of the Lynch-Granger model intuitively, and suggests which of the many biological facts introduced into the original model are relevant to this ...

Piriform Cortex and Olfactory Tubercle
2014This chapter describes perspectives on the possible functional logic of neuronal circuits in the central olfactory system. The central olfactory system has multiplex pathways and loops that connect the olfactory bulb, olfactory cortex, neocortex, thalamus, ventral striatum, amygdala, hippocampus, and hypothalamus.

Olfactory Frontal Cortex and Multiple Olfactory Processing in Primates
1991When we (Tanabe et al., 1974) began our studies on the brain mechanism of olfaction in our laboratory, we found that an olfactory projection area in the neocortex had not been studied physiologically and had been entirely unknown until Allen’s pioneer work (1940, 1943) appeared. In ablation and electrophysiological experiments on dogs, Allen found that

The Olfactory Cortex and the Ventral Striatum
1978The first part of the paper deals with the relations between the olfactory bulb and the olfactory cortex, represented by the rat and to a lesser extent the rhesus monkey. The second part addresses itself to the olfactory tubercle and its relation to the olfactory system on the one hand, and to the basal ganglia on the other.

Comparative Aspects of Olfactory Cortex
1990Three different types of cerebral cortex have traditionally been distinguished on the basis of structural, phylogenetic, and ontogenetic considerations (Ariens Kappers et al., 1936): neocortex, hippocampal archicortex, and olfactory paleocortex. An often-stated speculation with little experimental or theoretical support is that the neocortex evolved ...
