Scientists sniff out unexpected role for stem cells in the brain

For decades, scientists thought that neurons in the brain were born only during the early development period and could not be replenished. More recently, however, they discovered cells with the ability to divide and turn ...

How clutch molecules enable neuron migration

The brain can discriminate over 1 trillion odors. Once entering the nose, odor-related molecules activate olfactory neurons. Neuron signals first accumulate at the olfactory bulb before being passed on to activate the appropriate ...

Map of brain connections provides insight into olfactory system

The processing of sensory information in the brain involves a complex network of neural connections specific to each type of sensory input. Much is known about the neural wiring associated with most senses, but the deeper ...

Understanding how neurons shape memories of smells

In a study that helps to deconstruct how olfaction is encoded in the brain, neuroscientists at University of California, San Diego School of Medicine have identified a type of neuron that appears to help tune, amplify and ...

Nose's response to odors more than just a simple sum of parts

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. ...

The relentless dynamism of the adult brain

Scientists from the Institut Pasteur and the CNRS were able to make real-time observations over a period of several months that reveal how new adult-born neurons are formed and evolve in the olfactory bulb of mice. They made ...

'Zombie' brain cells develop into working neurons

Preventing the death of neurons during brain growth means these 'zombie' cells can develop into functioning neurons, according to research in fruit flies from the Crick, the University of Lausanne (UNIL) and the Max Planck ...
