Inhibitory receptive fields were derived at 35 controls and 42 PA sites using two-tone stimulus paradigms in which varying "masker" tones suppressed cortical responses to a fixed "probe" tone [23].
For each pair a varying "masker" tone suppressed cortical responses to a fixed "probe" tone selected near neuron's CF, but had an intensity 10 20 dB SPL above threshold, in order to evoke reliable responses when presented alone.
In a repeated reference protocol, a fixed reference tone (e.g., 1000 Hz) is presented on each and every trial.
The merry band of scientists over at Microsoft Research — who apparently get paid to have fun and speak with fixed tones over videos — have put together something called FlexSense, a flat piece of bendable material loaded with sensors.
The 60 tones used were those that, as dyadic combinations with a fixed tonic, had the greatest percentage similarity to a harmonic series.
Maybe today I could consider myself a composer, but not a traditional one: I don't compose a fixed set of tones or sounds, I try to combine technology, space and social behavior in order to generate a flow of sound events.
Jintishi poetry, or regulated verse, is in the form of eight-line stanzas or seven characters per line with a fixed pattern of tones that required the second and third couplets to be antithetical (although the antithesis is often lost in translation to other languages).
A more likely explanation however is the fact that whereas the target tone in Halliday et al.'s study [29] could have been presented in either of 3 temporal intervals, the 'different' tones in the current study were presented in a fixed temporal position (the 2nd tone) within the trial.
The RTs belonging to each AN are separated from each other using orthogonal frequency division multiple access (OFDMA) with N tones over a fixed bandwidth, where only one RT is active at each frequency tone.
where P is a fixed power for the pilot tone, σ2 is noise variance, H is hermitian matrix, t is matrix pseudo inverse, tr is trace, E is expectation [9, 10].
