Auditory perceptual decisions are encoded diffusely across frontal and parietal cortex.

Evidence

Whereas a single cortical locus of decision-making has yet to materialize, decision-related activity is seen throughout the frontal lobe. vlPFC neurons are strongly modulated by monkeys’ choices (Russ et al. 2008 ; Lee et al. 2009 ). Neural activity in the inferior frontal lobe of the human cortex is also modulated by choice when listeners judge the content of ambiguous speech sounds (Binder et al. 2004 ). Neural correlates relating to a listeners’ decision on auditory-flutter stimuli have also been observed in the ventral premotor cortex (Lemus et al. 2009a ). Interestingly, as noted above, the dorsal pathway also contributes to auditory perception; consistent with that notion, activity in the human parietal lobe is modulated by listeners’ choices (Cusack 2005 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4891
