World premiere of brain orchestra Mar 18, 2010
The performers launch sounds or affect their frequencies and modulations based on two well-characterised effects seen in EEGs: the steady-state visually evoked potential (SSVEP), and the so-called P300 signal ... One of them affects the volume of a given sound - known to influence the level of arousal in the circumplex model - and the other affects a certain modulation of that sound, which is known to influence the valence, how positive or negative the arousal is emotionally.

Multicenter NIH clinical trial will study potential benefits of brain cooling after a stroke Mar 10, 2010
In the ICTuS 2 trial, investigators will use an endovascular temperature modulation system from Philips Healthcare. Endovascular cooling provides rapid heat exchange and very fast cooling toward target temperature; in awake patients, endovascular cooling is generally superior to cooling blankets or ice packs in maintaining tight temperature control around the target temperature.

Finding tears behind the straight face Mar 3, 2010
Written in a single movement with intriguing rhythmic modulation, the ending gives the impression that the unifying pulse that has remained present during both fast and slow music throughout is gradually ceasing, and time starts standing still. At one point Shostakovich's rhythmic games require some of the players to tap the body of their instrument with the bow tip. (Sydney Morning Herald -- Entertainment)

Fujitsu Develops Compact Frequency-Synthesizer for Terrestrial Digital TV Broadcast Tuners Feb 10, 2010
Synthesizers, a major component in these tuners, have typically used delta-sigma modulation in a fractional multiples method ... Furthermore, with the conventional delta-sigma modulation/fractional multiples method, in order to create a dual-tuner, two external filters are required, thus further increasing the size of the module.

Gene Essential for Neuron Development and Contextual Memory Jan 26, 2010
"More generally," concludes the CNR researcher, "our results show that the correct differentiation of the neuron is critical for its activation within memory circuits. In fact, a deficit of contextual or spatial memory occurs also following a transient acceleration of the differentiation of neural progenitor cells -- as shown in our previous studies -- and thus not only after a delay of differentiation, as observed here. "We believe that these researches, through a modulation or alteration of... (Science Daily)
