New neurons in the adult brain are involved in sensory learning

Although we have known for several years that the adult brain can produce new neurons, many questions about the properties conferred by these adult-born neurons were left unanswered. What advantages could they offer that ...

What's that smell? The advantage of sniffing

Researchers led by Takeshi Imai at the RIKEN Center for Developmental Biology (CDB) have discovered how the physical and sensory perceptions associated with sniffing are kept separate and why sniffing can help identify odors, ...

Elderly who have trouble identifying odors face risk of dementia

A long-term study of nearly 3,000 adults, aged 57 to 85, found that those who could not identify at least four out of five common odors were more than twice as likely as those with a normal sense of smell to develop dementia ...

Early odor exposure enhances response of smell cells

Mice exposed to scents of mint or fresh cut grass before and shortly after birth show increased responses in a specific population of odor-processing neurons to a variety of odors, according to new research published in eNeuro. ...

Close or far, how smell tells us it's popcorn

People know a smell is popcorn whether it is cooking down the hallway or held right under their noses. Yale researchers Douglas Storace and Lawrence Cohen in the Department of Cellular and Molecular Physiology have found ...

Distant brain regions selectively recruit stem cells

Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the University of Basel reports in the current issue of Science that long-distance brain connections ...

The human sense of smell: It's stronger than we think

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.

New role of adenosine in the regulation of REM sleep discovered

The regulation and function of sleep is one of the biggest black boxes of today's brain science. A new paper published online on August 2 in the journal Brain Structure & Function finds that rapid eye movement (REM) sleep ...
