Decreased olfactory function is very common in the older population, being present in over
half of those between the ages of 65 and 80 years and in over three quarters of those over …

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 …

We present a neural algorithm for the rapid online learning and identification of odourant
samples under noise, based on the architecture of the mammalian olfactory bulb and …

Increased understanding of the early stages of olfaction has lead to a renewed interest in the
higher brain regions responsible for forming unified 'odor images' from the chemical …

It is surprising that the piriform cortex, when compared to the hippocampus, has been given
relatively little significance in human epilepsy. Like the hippocampus, it has a …

Cholinergic modulation of central circuits is associated with active sensation, attention, and
learning, yet the neural circuits and temporal dynamics underlying cholinergic effects on …

Despite major anatomical differences with other mammalian sensory systems, olfaction
shares with those systems a modulation by sleep/wake states. Sleep modulates odor …

Highlights•Neuromodulators are widely represented throughout olfactory networks.•
Neuromodulators have diverse actions on cortical circuits.•Olfactory computations are …

The tractable, layered architecture of the olfactory bulb (OB), and its function as a relay
between odor input and higher cortical processing, makes it an attractive model to study how …

Background: Although conflicting findings abound, gender-related differences in olfactory
identification have received continuous attention. To our best knowledge, no systematic and …
