The biological olfactory system is the sensory system responsible for the detection of the
chemical composition of the environment. Several attempts to mimic biological olfactory …

Remarkable advances in our understanding of olfactory perception have been made in
recent years, including the discovery of new mechanisms of olfactory signaling and new …

Sensation is an active process involving the sampling and central processing of external
stimuli selectively in space and time. Olfaction in particular depends strongly on active …

The locus coeruleus-norepinephrine (LC-NE) system is involved in many brain functions
and neurological disorders. In this review we discuss how LC-NE signaling affects the …

Centrifugal serotonergic fibers innervate the olfactory bulb, but the importance of these
projections for olfactory processing is unclear. We examined serotonergic modulation of …

A comprehensive systems overview of sensory and reward processing in the brain, this book
explores what reward processing can teach us about the senses and what sensory …

The serotonergic raphe nuclei are involved in regulating brain states over timescales of
minutes and hours. We examined more rapid effects of raphe activation on two classes of …

In social animals, the presence of an affiliative conspecific alleviates acute stress responses,
and this is called social buffering. We previously reported in male rats that the presence of a …

The noradrenergic locus coeruleus (LC) mediates key aspects of arousal, memory, and
cognition in structured tasks, but its contribution to naturalistic behavior remains unclear. LC …

On the basis of its primary circuit it has been postulated that the olfactory bulb (OB) is
analogous to the retina in mammals. In retina, repeated exposure to the same visual …
