“…These results have been replicated in both listening and reading (Bemis & Pylkkänen, 2013) as well as in production (Pylkkänen, Bemis, & Blanco Elorrieta, 2014), suggesting they are not modality-specific. Further, similar results have been obtained by Baron, Thompson-Schill, Weber, and Osherson (2010), Baron and Osherson (2011), who showed that the LATL is engaged in conceptual combination across and within words.…”

“…Interestingly, this region was also recently identified in a study of conceptual combination (Baron and Osherson 2011). Here, the authors found that multivoxel patterns in this cortical location encode the semantic relationship between word combinations (such as "man" and "child") and related concepts (boy).…”

Creating Concepts from Converging Features in Human Cortex

To make sense of the world around us, our brain must remember the overlapping features of millions of objects. Crucially, it must also represent each object's unique feature-convergence. Some theories propose that an integration area (or "convergence zone") binds together separate features. We report an investigation of our knowledge of objects' features and identity, and the link between them. We used functional magnetic resonance imaging to record neural activity, as humans attempted to detect a cued fruit or vegetable in visual noise. Crucially, we analyzed brain activity before a fruit or vegetable was present, allowing us to interrogate top-down activity. We found that pattern-classification algorithms could be used to decode the detection target's identity in the left anterior temporal lobe (ATL), its shape in lateral occipital cortex, and its color in right V4. A novel decoding-dependency analysis revealed that identity information in left ATL was specifically predicted by the temporal convergence of shape and color codes in early visual regions. People with stronger feature-and-identity dependencies had more similar top-down and bottom-up activity patterns. These results fulfill three key requirements for a neural convergence zone: a convergence result (object identity), ingredients (color and shape), and the link between them.

“…Some investigators claim that specific portions of the anterior temporal lobe, the focus of disease in svPPA, may serve as a potential convergence zone (Davies et al 2004, Knibb et al 2006). Other research with repetitive transcranial magnetic stimulation (rTMS) and functional magnetic resonance imaging (fMRI) has also emphasized the role of the anterior temporal lobe in word meaning (Baron & Osherson 2011; Bemis & Pylkkanen 2011; Pobric et al 2007, 2010; Visser & Lambon Ralph 2011). However, the multimodal nature of the ventral temporal lobe has not been confirmed by others (Bonner et al 2013, Price et al 2015).…”

Primary progressive aphasia (PPA) refers to a disorder of declining language associated with neurodegenerative diseases such as frontotemporal degeneration and Alzheimer disease. Variants of PPA are important to recognize from a medical perspective because these syndromes are clinical markers suggesting specific underlying pathology. In this review, I discuss linguistic aspects of PPA syndromes that may prove informative for parsing our language mechanism and identifying the neural representation of fundamental elements of language. I focus on the representation of word meaning in a discussion of semantic variant PPA, grammatical comprehension and expression in a discussion of nonfluent/agrammatic variant PPA, the supporting role of short-term memory in a discussion of logopenic variant PPA, and components of language associated with discourse in a discussion of behavioral variant frontotemporal dementia. PPA provides a novel perspective that uniquely addresses facets of language and its disorders while complementing traditional aphasia syndromes that follow stroke.
