... technology, carp-specific biocides, pheromone and sensory attractants. "It is anticipated that if these technologies are proven to be effective and safe, they will be applied on-ground in an integrated pest fish control program for the Murray-Darling Basin," Dr Crane says. Earlier outbreaks occurred in U...

Slow brain waves play key role in coordinating complex activity

...ler on the brain, and is associated with bottom-up sensory or motor processing, while the theta rhythm is much more spatially widespread, the size of a silver dollar or larger on the surface of the cortex, and is tied to top-down executive processes like attention and memory. Coupling between these two rhyth...

Mirrors in the mind: New studies elucidate how the brain reflects onto itself the actions of others

Bitter taste identifies poisons in foods

...matrix," said senior author Paul Breslin, a Monell sensory scientist. Glucosinolates act as anti-thyroid compounds. The thyroid converts iodine into thyroid hormones, which are essential for protein synthesis and regulation of the body's metabolism. Glucosinolates inhibit iodine uptake by the thyroid, in...

Zinc plays important role in brain circuitry

...ctions as a modulator of neurons in both motor and sensory signaling pathways in the brain and spinal cord. The genetic approach used by the researchers was a more targeted technique than previous experiments in which researchers reduced overall neuronal zinc levels using chemicals called chelators that s...

Paying attention sets off symphony of cell synchronization

... how attention improves the perception of incoming sensory stimulation has been a long-time concern of scientists. One hypothesis is that when you pay attention neurons produce stronger brain activity, as if the stimulus itself was stronger. That would mean that paying attention might make something appear m...

Striking the right balance between excitation and inhibition

...ab form a relay station receiving and interpreting sensory signals from the environment and then sending them to the brain. In doing so these neurons evaluate the strength of sensations. "An example of how the system works is illustrated by what happens when you cut your finger," Goulding explains. "Initial...

By tweaking portions of the TRH molecule, the researchers developed six slightly edited versions, while retaining most of the properties of the natural hormone. Measuring the cellular response when hor...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

"Human consciousness…is a function of the ebb and flow of neural impulses in various regions of the brain-the very substrate that drugs such as psilocybin act upon," Schuster says. "Understanding what mediates these effects is clearly wi...

Stimulation of the semicircular canals can artificially control human walking and balance

Flick of whiskers helps tease out brain's 'shadow' signaling system

While it's been shown before that astrocytes can become activated under extreme conditions in the laboratory, Nedergaard said th...

Primates take weather into account when searching for fruits
