Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the auditory system ...

Olfactory receptors, present on the surface of sensory neurons in the nasal cavity, recognize odorant molecules and relay this information to the brain. How do these neurons manage to detect a large variability of signals ...

Take a sniff of a freshly poured glass of wine, and the prevailing scientific thinking would suggest that the harmony of fragrances involves sensory receptors in the nose simply adding up the individual odors they encounter. ...

Just as humans use their noses for the sense of smell, insects such as fruit flies use their antennae—covered in sensory hairs called sensilla—for olfaction. In flies, the sense of smell plays a fundamental role in courtship.

A team of neuroscientists at the Champalimaud Centre for the Unknown (CCU), in Lisbon (Portugal), has performed one of the first studies into the central neural circuits (or higher brain areas) that underlie innate responses ...

In a new study, Columbia scientists have discovered why the brain's olfactory system is so remarkably consistent between individuals, even though the wiring of brain cells in this region differs greatly from person to person. ...

When it comes to our sense of smell, we have been led to believe that animals win out over humans: No way can we compete with dogs and rodents, some of the best sniffers in the animal kingdom.

Research at the RIKEN Brain Science Institute in Japan has revealed that a molecule involved in fish reproduction activates the brain via the nose. The pheromone is released by female zebrafish and sensed by smell receptors ...

The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor ...
