The vibrational theory of olfaction for the win

(Medical Xpress)—As occurred in the painstaking deciphering of Egyptian hieroglyphs, adherence to outmoded ideas is a lasting impediment to our understanding of how odorants are decoded by the olfactory system. The primary ...

Locusts reveal how neurons distinguish multiple odors

(Medical Xpress)—Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such ...

Why the sense of smell declines in old age

As mammals age, their sense of smell deteriorates. In a study published in the journal Cell Reports, an interdisciplinary research team at Helmholtz Zentrum München and the University Medical Centre Mainz investigated why ...

What's that smell? Scientists find a new way to understand odors

Every smell, from a rose to a smoky fire to a pungent fish, is composed of a mixture of odorant molecules that bind to protein receptors inside your nose. But scientists have struggled to understand exactly what makes each ...

Scientists uncover new details in how sense of smell develops

Dogs, known for their extraordinarily keen senses of smell, can be trained to use their sensitive sniffers to find drugs, bombs, bed bugs, missing hikers and even cancer. Among dogs and other animals that rely on smell, at ...

Scientists uncover new connection between smell and memory

Neurobiologists at the University of Toronto have identified a mechanism that allows the brain to recreate vivid sensory experiences from memory, shedding light on how sensory-rich memories are created and stored in our brains.

Brain can navigate based solely on smells

Northwestern University researchers have developed a new "smell virtual landscape" that enables the study of how smells engage the brain's navigation system. The work demonstrates, for the first time, that the mammalian brain ...
