To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system's flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then...

Stowers investigators reveal a developmental switch in targeting capacity of olfactory neurons 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 and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain. This convergence, or wiring pattern, is often described as an...

Skin cells use new molecule to send touch information to the brain In a study published in the April 6 online edition of the journal Nature, a team of Columbia University Medical Center researchers led by Ellen Lumpkin, PhD, associate professor of somatosensory biology, solve an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures. Touch is the last frontier of sensory neuroscience. The cells and molecules that initiate...

A study led by scientists at The Scripps Research Institute (TSRI) has helped solve a long-standing mystery about the sense of touch. The "gentle touch" sensations that convey the stroke of a finger, the fine texture of something grasped and the light pressure of a breeze on the skin are brought to us by nerves that often terminate against special skin cells called Merkel cells. These skin cells' role in touch sensation has long been debated in the scientific community. The new study,...

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by...

By studying nerve cells that originated in patients with a severe neurological disease, a University of Wisconsin-Madison researcher has pinpointed an error in protein formation that could be the root of amyotrophic lateral sclerosis. Also called Lou Gehrig's disease, ALS causes paralysis and death. According to the ALS Association, as many as 30,000 Americans are living with ALS. After a genetic mutation was discovered in a small group of ALS patients, scientists transferred that gene...

For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has...

Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding, described in Nature Communications, will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis (ALS). The new method involves adding critical signaling molecules to precursor cells a few days earlier than previous methods...

KIT computer models explain how ion channels in cell membranes react to light / light switch for nerve cells as a sensitive tool of research Networked nerve cells are the control center of organisms. In a nematode, 300 nerve cells are sufficient to initiate complex behavior. To understand the properties of the networks, re-searchers switch cells on and off with light and observe the resulting behavior of the organism. In the Science journal, sci-entists now present a protein that...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
