“…The asymmetry in decoding direction is significant (P < 0.001). This phenomenon of asymmetric generalization has been reported in other studies (28)(29)(30)(31), and the exact source remains unclear (32). One possible interpretation that has been put forward is that it reflects the underlying nature of the representations; for instance, the auditory trials might activate only a subset of voxels that contain categorical information, whereas the visual trials activate the majority of VTC voxels.…”

To what extent does functional brain organization rely on sensory input? Here, we show that for the penultimate visual-processing region, ventral-temporal cortex (VTC), visual experience is not the origin of its fundamental organizational property, category selectivity. In the fMRI study reported here, we presented 14 congenitally blind participants with face-, body-, scene-, and object-related natural sounds and presented 20 healthy controls with both auditory and visual stimuli from these categories. Using macroanatomical alignment, response mapping, and surface-based multivoxel pattern analysis, we demonstrated that VTC in blind individuals shows robust discriminatory responses elicited by the four categories and that these patterns of activity in blind subjects could successfully predict the visual categories in sighted controls. These findings were confirmed in a subset of blind participants born without eyes and thus deprived from all light perception since conception. The sounds also could be decoded in primary visual and primary auditory cortex, but these regions did not sustain generalization across modalities. Surprisingly, although not as strong as visual responses, selectivity for auditory stimulation in visual cortex was stronger in blind individuals than in controls. The opposite was observed in primary auditory cortex. Overall, we demonstrated a striking similarity in the cortical response layout of VTC in blind individuals and sighted controls, demonstrating that the overall category-selective map in extrastriate cortex develops independently from visual experience.ategory selectivity in human and primate visual cortex is a striking example of how the brain encodes the outer world. Mostly found on the lateral and ventral parts of the temporal lobe, several distinct macroscopic brain regions are known to have a preference for a particular category of visual objects, including faces [fusiform face area, occipital face area (1)], body parts [extrastriate body area (2), fusiform body area (3)], artificial objects [lateral occipital complex (4)], and scenes [parahippocampal place area (5)]. The exact computational mechanisms that drive these regions are still largely unknown: Do these regions operate as distinct functional modules (1, 6), or is category selectivity fully distributed across ventral-temporal cortex (VTC) (7), ora combination of both-do category-selective regions reflect peaks in a broad tuning map for visual object features (8)?A prominent question is whether this functional architecture develops independently of visual input or relies on visual experience during early infancy and the following years. As an example of the latter, a key hypothesis indicates that the global functional organization of VTC starts out as a protomap with a retinotopic layout (9-11). Through visual experience, regions within this protomap develop selectivity for the visual categories that often appear in the retinotopic region that is represented. According to this perspective, because faces most likely appear...

“…aIPS is also related to a multi-modal or abstract action representation revealed by recent MVPA studies (Ogawa and Inui 2011;Oosterhof et al 2012). Furthermore, the anterior part of IPL in the left hemisphere is related to encoding action goals (Hamilton and Grafton 10 2006) or tool-related action outcomes (Leshinskaya and Caramazza 2015).…”

Previous neuropsychological studies of ideomotor apraxia (IMA) indicated impairments in pantomime actions for tool use for both right and left hands following lesions of parieto-premotor cortices in the left hemisphere. Using functional magnetic resonance imaging (fMRI) with multi-voxel pattern analysis (MVPA), we tested the hypothesis that 5 the left parieto-premotor cortices are involved in the storage or retrieval of hand-independent representation of tool use actions. In the fMRI scanner, one of three kinds of tools was displayed in pictures or letters, and the participants made pantomimes of the use of these tools using the right hand for the picture stimuli or with the left hand for the letters. We then used MVPA to classify which kind of tool the subjects were pantomiming. 10Whole-brain searchlight analysis revealed successful decoding using the activities largely in the contralateral primary sensorimotor region, ipsilateral cerebellum, and bilateral early visual area, which may reflect differences in low-level sensorimotor components for three types of pantomimes. Furthermore, a successful cross-classification between the right and left hands was possible using the activities of the left inferior parietal lobule (IPL) near the 15 junction of the anterior intraparietal sulcus. Our finding indicates that the left anterior intraparietal cortex plays an important role in the production of tool-use pantomimes in a hand-independent manner, and independent of stimuli modality.

“…Notably, the degree of such shared activation appears to vary with the complexity of the imagined musical stimulus, with more shared activation for simple stimuli than for complex stimuli such as ecologically valid music (Schaefer et al, 2013). The overlap between imagery and perception is not unique to the auditory modality; both visual and movement imagination have been found to activate modality-specific brain regions (Kosslyn et al, 2001; Pfurtscheller et al, 2006), and imagery content can even be decoded from the brain responses in visual and motor areas (Cichy et al, 2012; Oosterhof et al, 2012). The implication is that aspects of the imagined stimulus or action are being processed much in the way the actually perceived stimulus or performed action might be, usually with a weaker signature in modality-specific regions (Kosslyn et al, 2001) and together with additional, modality non-specific frontal and parietal activations that are related to imagery quality or vividness, likely involving memory and attentional processes related to the cognitive effort of imagining (Daselaar et al, 2010).…”

Music is commonly used to facilitate or support movement, and increasingly used in movement rehabilitation. Additionally, there is some evidence to suggest that music imagery, which is reported to lead to brain signatures similar to music perception, may also assist movement. However, it is not yet known whether either imagined or musical cueing changes the way in which the motor system of the human brain is activated during simple movements. Here, functional magnetic resonance imaging was used to compare neural activity during wrist flexions performed to either heard or imagined music with self-pacing of the same movement without any cueing. Focusing specifically on the motor network of the brain, analyses were performed within a mask of BA4, BA6, the basal ganglia (putamen, caudate, and pallidum), the motor nuclei of the thalamus, and the whole cerebellum. Results revealed that moving to music compared with self-paced movement resulted in significantly increased activation in left cerebellum VI. Moving to imagined music led to significantly more activation in pre-supplementary motor area (pre-SMA) and right globus pallidus, relative to self-paced movement. When the music and imagery cueing conditions were contrasted directly, movements in the music condition showed significantly more activity in left hemisphere cerebellum VII and right hemisphere and vermis of cerebellum IX, while the imagery condition revealed more significant activity in pre-SMA. These results suggest that cueing movement with actual or imagined music impacts upon engagement of motor network regions during the movement, and suggest that heard and imagined cues can modulate movement in subtly different ways. These results may have implications for the applicability of auditory cueing in movement rehabilitation for different patient populations.
