“…Wheeler et al [2] reported reactivation of visual information in the left fusiform gyrus, and suggested that its activation is related to processing forms, colors, and texture of objects. In slight contrast, the left as well as the right fusiform gyri are activated during recognition of visual information such as pictures [17]. Cabeza and Nyberg [18] suggested that neural activation of border areas between the temporal and the occipital lobes, including the fusiform gyrus, plays a role in processing visual sensory input as well as visual imaging.…”

This study used magnetoencephalography (MEG) to examine the latency of modality-specific reactivation in the visual and auditory cortices during a recognition task to determine the effects of reactivation on episodic memory retrieval. Nine right-handed healthy young adults participated in the experiment. The experiment consisted of a word-encoding phase and two recognition phases. Three encoding conditions were included: encoding words alone (word-only) and encoding words presented with either related pictures (visual) or related sounds (auditory). The recognition task was conducted in the MEG scanner 15 min after the completion of the encoding phase. After the recognition test, a source-recognition task was given, in which participants were required to choose whether each recognition word was not presented or was presented with which information during the encoding phase. Word recognition in the auditory condition was higher than that in the word-only condition. Confidence-of-recognition scores (d') and the source-recognition test showed superior performance in both the visual and the auditory conditions compared with the word-only condition. An equivalent current dipoles analysis of MEG data indicated that higher equivalent current dipole amplitudes in the right fusiform gyrus occurred during the visual condition and in the superior temporal auditory cortices during the auditory condition, both 450-550 ms after onset of the recognition stimuli. Results suggest that reactivation of visual and auditory brain regions during recognition binds language with modality-specific information and that reactivation enhances confidence in one's recognition performance.

“…To allow subjects to view the object and their hand touching the object simultaneously, we manipulated effectiveness by changing the level of similarity among the objects and thus the difficulty of object recognition. There is evidence to suggest that increasing the level of similarity produces changes in effectiveness in object-selective brain regions in the desired direction for assessing inverse effectiveness ( Joseph & Farley, 2004). Thus, in the present experiment, we varied the level of behavioral performance and BOLD activation effectiveness by changing the similarity between objects, rather than by degrading them.…”

Visuo-haptic Neuronal Convergence Demonstrated with an Inversely Effective Pattern of BOLD Activation

We investigated the neural substrates involved in visuo-haptic neuronal convergence using an additive-factors design in combination with fMRI. Stimuli were explored under three sensory modality conditions: viewing the object through a mirror without touching (V), touching the object with eyes closed (H), or simultaneously viewing and touching the object (VH). This modality factor was crossed with a task difficulty factor, which had two levels. On the basis of an idea similar to the principle of inverse effectiveness, we predicted that increasing difficulty would increase the relative level of multisensory gain in brain regions where visual and haptic sensory inputs converged. An ROI analysis focused on the lateral occipital tactile-visual area found evidence of inverse effectiveness in the left lateral occipital tactile-visual area, but not in the right. A whole-brain analysis also found evidence for the same pattern in the anterior aspect of the intraparietal sulcus, the premotor cortex, and the posterior insula, all in the left hemisphere. In conclusion, this study is the first to demonstrate visuo-haptic neuronal convergence based on an inversely effective pattern of brain activation.

“…Matching of objects may also involve semantic processing, but it is not required for the matching task (in Figure 1, semantic processing is parenthesized). The degree of structural and perceptual similarity between nonmatching stimuli was parametrically varied as in Joseph and Farley (2004) and Joseph and Gathers (2003) to tap into the process of fine differentiation. Higher levels of similarity were expected to induce higher functional magnetic resonance imaging (fMRI) signal in brain regions involved in fine differentiation.…”

“…The second question is whether making fine distinctions among visually similar objects is specifically associated with mid-fusiform activation (Rogers et al, 2005; Gerlach, Law, & Paulson, 2004; Joseph & Farley, 2004; Joseph & Gathers, 2003; Price, Noppeney, Phillips, & Devlin, 2003; Gauthier et al, 1999; Gerlach, Law, Gade, & Paulson, 1999; Damasio, Grabowski, Tranel, Hichwa, & Damasio, 1996). Objects within the same category tend to overlap at the level of structural descriptions; consequently, the process of fine differentiation of objects (e.g., distinguishing different breeds of dogs) will require making fine distinctions among structural descriptions.…”

The present study explored constraints on mid-fusiform activation during object discrimination. In three experiments, participants performed a matching task on simple line configurations, nameable objects, three dimensional (3-D) shapes, and colors. Significant bilateral mid-fusiform activation emerged when participants matched objects and 3-D shapes, as compared to when they matched two-dimensional (2-D) line configurations and colors, indicating that the mid-fusiform is engaged more strongly for processing structural descriptions (e.g., comparing 3-D volumetric shape) than perceptual descriptions (e.g., comparing 2-D or color information). In two of the experiments, the same mid-fusiform regions were also modulated by the degree of structural similarity between stimuli, implicating a role for the mid-fusiform in fine differentiation of similar visual object representations. Importantly, however, this process of fine differentiation occurred at the level of structural, but not perceptual, descriptions. Moreover, mid-fusiform activity was more robust when participants matched shape compared to color information using the identical stimuli, indicating that activity in the mid-fusiform gyrus is not driven by specific stimulus properties, but rather by the process of distinguishing stimuli based on shape information. Taken together, these findings further clarify the nature of object processing in the mid-fusiform gyrus. This region is engaged specifically in structural differentiation, a critical component process of object recognition and categorization.
