Background Sensory perception is profoundly shaped by attention. Attending to an odor
strongly regulates if and how it is perceived–yet the brain systems involved in this process …

It is widely assumed that the thalamus is functionally irrelevant for the sense of smell.
Although animal studies suggest that the mediodorsal (MD) thalamus links primary olfactory …

Central 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 …

The representation of odor in olfactory cortex (piriform) is distributive and unstructured and
can only be afforded behavioral significance upon learning. We performed 2-photon …

A growing body of evidence shows that olfactory information is processed within a thalamic
nucleus in both rodents and humans. The mediodorsal thalamic nucleus (MDT) receives …

Identification of an object based on its odor alone is inherently difficult, but becomes easier
when other senses provide supporting cues. This suggests that crossmodal sensory input …

The capacity to pay attention is important for the cognitive ability, for example, evaluating an
object for its qualities. Attention can selectively prioritize the neural processes that are …

Processing of olfactory information is modulated by centrifugal projections from cortical
areas, yet their behavioral relevance and underlying neural mechanisms remain unclear in …

Odor information arrives first in the main olfactory bulb and is then broadcasted to the
olfactory cortices and striatum. Downstream regions have unique cellular and connectivity …

The mediodorsal thalamus (MDT) is a higher-order corticocortical thalamic nucleus involved
in cognition and memory. However, anatomically, the MDT is also the primary site of …
