Receiver operating characteristic (ROC) analysis [ 27] was used to assess how well the recorded neural signals encoded either the sound F0 or reported pitch.
Demonstrating whether neural activity within and beyond the putative pitch center correlates with reported pitch may help resolve the question of which representations of stimulus periodicity contribute to perception.
Neural sensitivity to both F0 and reported pitch varied according to cortical depth, with a greater percentage of deep recording sites having significant aROCF0 and aROCchoice values than those sites recorded in the superficial layers.
Surprisingly, although the stimulus F0 was well represented at the onset of the target sound, neural activity throughout auditory cortex frequently predicted the reported pitch better than the target F0.
S4 was a member of a previously reported pitch-tracking 'out' group (see [ 10]) as calculated by a composite score of Frequency Error of the fundamental frequency, Pitch Strength, and Frequency Error of the second harmonic in response to the "ya" stimulus.
A recent study in primates has reported pitch-selective neurons close to primary auditory cortex (Bendor and Wang 2005), consistent with human neuroimaging results, suggesting that a general code for pitch might emerge at, or below (Griffiths et al. 2001), this stage in the auditory pathway.
In October Guardian journalists (including John Domokos, Maeve Shearlaw, Patrick Kingsley and Richard Sprenger) ran practical workshops that covered the topics of Video Journalism, Investigative Reporting, pitching to the International Media and Social Media and Community.
The general lack of lateralization biases in pitch processing is moreover compatible with recent findings of another group (Hall and Plack 2009) but contradicts former studies reporting musical pitch processing being lateralized to the right PT (Patterson et al. 2002; Zatorre et al. 2002).
Conditions helped of course, with both captains and umpires reporting the pitch, the lethal and variable bounce less than ideal when facing the fearsome West Indian attack.
The banks edit and add to what they get from Copal, a research provider, then repackage the information under their own names as research reports, pitch books and trading recommendations.
