OK, so that's kind of a dopey little simple example to show you how you can use a functional localizer to directly answer a question like this, OK?
The use of a functional localizer to define a candidate region in each subject individually enabled us not just to make pictures of brain activation, but also to ask principled, hypothesis-driven questions about a thing in nature.
Together with LOC, which was targeted here using a specific functional localizer scan, also a region in the transverse occipital sulcus (TOS) has been previously associated with scene perception and the object processing [Dilks, et al., 2013; Grill-Spector and Malach, 2004; Schwarzlose, et al., 2008] and might have responded differentially to foreground/background targets in the current study.
Participants underwent 2 separate fMRI experiments: the main experiment using CFS masking and a functional localizer with fully visible text.
fMRI data were collected from one participant to provide a participant-specific example of how our technique can be used in combination with a functional localizer.
First, a functional localizer session using a block design with auditory speech, visual speech (lip movements, no audio), and audiovisual speech (audio and video-signal in sync) was used to identify areas activated by auditory and visual speech, which showed in addition further increased activity in the audiovisual condition.
Using a phase-encoding design as a functional localizer [Sanchez-Panchuelo et al., 2010], we restrict our analysis of the ER data to voxels in the vicinity of S1.
So the way you do that is you do something called running a functional localizer scan.
To identify target ROIs for neurofeedback training, each session began with a functional localizer (325 volumes, first 6 volumes discarded to ensure T1 equilibrium magnetization).
