Neuroscientists find genetic trigger that makes stem cells differentiate in nose epithelia University of California, Berkeley, neuroscientists have discovered a genetic trigger that makes the nose renew its smell sensors, providing hope for new therapies for people who have lost their sense of smell due to trauma or old age. The gene tells olfactory stem cells the adult tissue stem cells in the nose to mature into the sensory neurons that detect odors and relay that information to the...

'Sister' mitral cells may broadcast 2 distinct channels of information on odors to the cortex A team co-led by neuroscientists at Cold Spring Harbor Laboratory (CSHL) has shed light -- literally -- on circuitry underlying the olfactory system in mammals, giving us a new view of how that system may pull off some of its most amazing feats. It has long been known from behavioral experiments that rodents, for instance, can tell the difference between two quite similar odors in a single sniff. But...

Two new studies reveal that the commonly used insect repellents DEET and citronellal each work through a dual stimulation of insect sensory systems. The research findings, published by Cell Press on August 26 in the journals Neuron and Current Biology, enhance our understanding of how insects respond to repellents and may lead to the discovery of improved compounds for controlling insect-borne disease. Insect pests pose a major threat to humans across the world. In addition to spreading...

Heidelberg neuroscientists verify for the first time the function of inhibiting communication / Published in "Neuron" Whether different odors can be quickly distinguished depends on certain synapses in the brain that inhibit nerve stimulation. The researchers in Professor Dr. Thomas Kuner's team at the Institute of Anatomy and Cell Biology at Heidelberg University Medical School and Dr. Andreas Schäfer at the Max Planck Institute for Medical Research have shown that mice in which a...

New research provides valuable insight into the molecular mechanisms that allow experience to influence behavior. The study, published by Cell Press in the January 15th issue of the journal Neuron, shows that a normally repressive protein can promote plasticity in sensory neurons by linking odor stimulation with the synthesis of a key adaptation protein. Successful organisms must be able to adjust their behavior as a result of their experiences. This requires sensory neurons that can...
