G protein-coupled receptors (GPCRs) transduce various extracellular signals, such as
neurotransmitters, hormones, light, and odorous chemicals, into intracellular signals via G …

Rodents acquire more information from the sense of smell than humans because they have
a nearly fourfold greater variety of olfactory receptors. They use olfactory information not only …

The primary olfactory (or piriform) cortex is a trilaminar paleocortex that is seen increasingly
as an attractive model system for the study of cortical sensory processing. Recent findings …

Similar to fingerprints, humans have unique, genetically determined body odours. In case of
urine, the odour can change due to variations in diet as well as upon infection or tumour …

When animals smell a predator odor such as 2, 5-Dihydro-2, 4, 5-trimethylthiazoline (TMT),
even if it is a novel substance, the hypothalamo–pituitary–adrenal (HPA) axis is activated …

Enantiomeric pairs of mirror-image molecular structures are difficult to resolve by
instrumental analyses. The human olfactory system, however, discriminates (−)-wine lactone …

In vitro studies performed on brain slices demonstrate that the potassium channel blocker 4-
aminopyridine (4AP, 50 μM) discloses electrographic seizure activity and interictal …

The olfactory tubercle (OT), a trilaminar structure located in the basal forebrain of mammals,
is thought to play an important role in olfaction. While evidence has accumulated regarding …

Abstract Predator odors, such as 2, 5-dihydro-2, 4, 5-trimethylthiazoline (TMT), induce a
stress-like behavior in some rodents, and there is activation of a complex mix of brain …

Since the discovery of the superfamily of approximately 1000 odorant receptor genes in
rodents, the structural simplicity as well as the complexity of the olfactory system have been …
