What happens when we sleep

... study. "Our study markedly demonstrates that MCH neurons discharge in a reciprocal manner to the Orx neurons across the sleep-wake cycle." Dr. Jones and ... though they comprise less than 10% of the nerve cells in the LH. The reciprocal profiles and roles of the Orx and MCH neurons could be significant in the ...

Researchers disprove 15-year-old theory about the nervous system

... for signal transmission because it increases nerve conduction velocity," Garcia said. "The relationship between axons and myelinating cells is a reciprocal one, with each cell type sending and receiving signals from the other cell. One signal originates from myelinating cells and results in a large ...

Zooming in on genetic shuffling

... crossover. In a different type of recombination, called non-crossover, a small piece of DNA is copied from one chromosome onto the other without reciprocal exchange leading to gene conversion. Non-crossovers are minute events with a subtler effect than the exchange of larger fragments, but both types of ...

Stowers Proteomics Center devises method for assigning probabilities to human protein interactions

... for two proteins to associate is calculated from the bait-to-prey relationship alone, an improvement over other methods requiring systematic reciprocal bait-prey interactions or co-purification of preys by a third bait. Previous protein interaction networks built using protein mass spectrometry ...

... and intelligence: Hilleke Hulshoff Pol presents persuasive evidence how genetic factors influence the brain structure opening new insights into the reciprocal gene-environment developmental pathways. The role and therapeutic opportunities of cannabinoids: Raphael Mechoulam also last year winner ...

Research finds music training 'tunes' human auditory system

... a person may actually be tuning the brainstem," says Kraus. "This suggests that the relationship between the brainstem and neocortex is a dynamic and reciprocal one and tells us that our basic sensory circuitry is more malleable than we previously thought." Overall, the findings assist in unfolding new ...

Striking the right balance between excitation and inhibition

... the team found that a receptor protein known as Notch, which was already known to regulate maturation of neurons from neural stem cells, has a reciprocal function in precursors of inhibitory and excitatory neurons: cells with high levels of activated Notch became excitatory neurons, while cells with ...

Links between DNA damage and breast cancer studied

... breast cancer rises. "Collectively," they observe, "the findings reveal that the structural changes in DNA described may potentially disrupt normal reciprocal interactions between the cell types, thus increasing breast cancer risk." The findings suggest that lesions measured in the DNA of the stroma, which ...

DNA self-assembly used to mass-produce patterned nanostructures

... arm of the cross, about 10 nanometers long, had a pair of "sticky ends" where the DNA strand was made of up of unpaired bases that tend to bind with reciprocal bases. Tiles with complementary sticky ends link together when mixed. The structure of the tiles created the molecular equivalent of puzzle pieces ...

Divergent mating systems and parental conflict as a barrier to hybridization in flowering plants

... incompatibility, in which pollen from self-incompatible populations can successfully fertilize ovules of self-compatible individuals, but the reciprocal cross fails. Since both pre- and post-zygotic consequences of this imbalanced conflict can perturb successful fertilization and development, they ...

Specialized immune-system B cells play double-barreled role

... that the B-1a cells regulate the innate immune response and the B-1b cells regulate the adaptive, long-term immune response. Said Haas, "This reciprocal contribution of these two subtypes of B-1 cells to innate and acquired immunity was surprising to us. No one knew much about what these subsets do. ...
