Dear SPMers,
apologoies for the off-topic question:
In the visual system, it has been shown that areas such as the fusiform
face area (FFA) or the parahippocampal place area (PPA) can be easily
localized (e.g. independently by a quick localizer scan) and that
activity in these areas is attention and task dependent (e.g. Serences,
Schwarzbach, Courtney, Golay & Yantis (2004), Control of object based
attention in human cortex, Cerebral Cortex. or Egner & Hirsch, 2005,
Cognitive control mechanisms resolve conflict..., Nature Neuroscience)
Is there a comparable area in the auditory system?
That means:
- easy to identify by a brief localiser scan
- modulated by simple and plain attentional modulations
- responds to different brief auditory stimuli which can be used in a
speeded choice task (e.g. high tone vs low tone, syllable spoken in high
vs low pitch or male vs female speaker, or artificial sounds like gongs
vs clicks, etc)
I presume that an attentional or task-related modulation of activity is
the easier the higher-level the area is.
I'm just overwhelmed by the amount of literature concerning attention in
the auditory cortex per se, and so far I didn't find a study comparable
to the abovementioned (Serences et al., Egner & Hirsch) which employed
the ROI-by-localizer approach in the auditory cortex. Has something like
this been done? I'm not interested in investigating this effect, I just
would like to utilize it for a completely difference research question.
Any help would be greatly appreciated!
Thanks a lot &
Kind Regards,
Andre
