“…Previous fMRI studies that investigated syntactic phrase structure violations reported activations in the left frontal operculum adjacent to BA44 rather than in BA44, in addition to activations in the STG [Brauer and Frederici, 2007;. The left BA44, however, has been shown to be involved in syntactic processing when syntactic complexity was varied [Lee and Newman, 2010;Makuuchi et al, 2009], or when processing demands for sentences with syntactic phrase structure violations increases due to participants' inproficiency in the language [Brauer and Friederici, 2007;Rü schemeyer et al, 2005], or when sentences containing phrase structure violations were randomly mixed with unintelligible sentences [Friederici et al, 2010]. Furthermore, in an fMRI study using visually presented twoword phrases which included a syntactic word category violation, activation was found in the left BA44 as well [Kang et al, 1999].…”

In language processing, the relative contribution of early sensory and higher cognitive brain areas is still an open issue. A recent controversial hypothesis proposes that sensory cortices show sensitivity to syntactic processes, whereas other studies suggest a wider neural network outside sensory regions. The goal of the current event-related fMRI study is to clarify the contribution of sensory cortices in auditory syntactic processing in a 2 × 2 design. Two-word utterances were presented auditorily and varied both in perceptual markedness (presence or absence of an overt word category marking "-t"), and in grammaticality (syntactically correct or incorrect). A multivariate pattern classification approach was applied to the data, flanked by conventional cognitive subtraction analyses. The combination of methods and the 2 × 2 design revealed a clear picture: The cognitive subtraction analysis found initial syntactic processing signatures in a neural network including the left IFG, the left aSTG, the left superior temporal sulcus (STS), as well as the right STS/STG. Classification of local multivariate patterns indicated the left-hemispheric regions in IFG, aSTG, and STS to be more syntax-specific than the right-hemispheric regions. Importantly, auditory sensory cortices were only sensitive to the overt perceptual marking, but not to the grammaticality, speaking against syntax-inflicted sensory cortex modulations. Instead, our data provide clear evidence for a distinction between regions involved in pure perceptual processes and regions involved in initial syntactic processes.

“…This study combines data from three separate studies with overlapping stimuli (Lee & Newman, 2010; Newman et al, 2009, 2010); the non-overlapping stimuli were treated as fillers of no interest. Each study was composed of three sessions, training, imaging and debriefing sessions.…”

This study explores the interaction between working memory systems - episodic and verbal working memory - and language processing by examining how differences in working memory capacity (WMC) modulated neural activation levels and functional connectivity during sentence comprehension. Activation of the inferior frontal gyrus and medial prefrontal cortex was correlated with WMC during the probe phase, suggesting that not all of the activation observed in the left IFG is language-specific, but is instead related to executive processes recruited during comprehension. Posterior cingulate/precuneus activation was negatively correlated with WMC scores during sentence reading. In addition, functional connectivity between the PCC and IFG was positively correlated with WMC while that between the PCC and the inferior parietal cortex was negatively correlated with WMC. Together these results suggest that high-capacity and low capacity readers may utilize different processing strategies with high capacity readers utilizing episodic memory systems during sentence reading to generate a representation of the events (event representation). Both groups use executive working memory processes during the probe phase.

“…Such “reading for meaning” adds layers of complexity such as syntax and grammar. Efforts are underway to study these other components of reading (Yarkoni et al, 2008; Lee and Newman, 2010) while being able to measure task compliance via a measured response. Yet, designing and implementing experimental paradigms that can both present such complex stimuli in a controlled way and allow for the attribution of neural responses to particular parts of these stimuli is non-trivial.…”

Matching is not naming: A direct comparison of lexical manipulations in explicit and implicit reading tasks

The neurobiological basis of reading is of considerable interest, yet analyzing data from subjects reading words aloud during functional MRI data collection can be difficult. Therefore, many investigators use surrogate tasks such as visual matching or rhyme matching to eliminate the need for spoken output. Use of these tasks has been justified by the presumption of “automatic activation” of reading-related neural processing when a word is viewed. We have tested the efficacy of using a non-reading task for studying “reading effects” by directly comparing BOLD activity in subjects performing a visual matching task and an item naming task on words, pseudowords (meaningless but legal letter combinations), and nonwords (meaningless and illegal letter combinations). When compared directly, there is significantly more activity during the naming task in “reading-related” regions such as the inferior frontal gyrus (IFG) and supramarginal gyrus. More importantly, there are differing effects of lexicality in the tasks. A whole-brain task (matching vs naming) by string type (word vs pseudoword vs nonword) by BOLD timecourse analysis identifies regions showing this three-way interaction, including the left IFG and left angular gyrus (AG). In the majority of the identified regions (including the left IFG and left AG), there is a string type by timecourse interaction in the naming but not the matching task. These results argue that the processing performed in specific regions is contingent on task, even in reading-related regions, and is thus non-automatic. Such differences should be taken into consideration when designing studies intended to investigate reading.
