During language comprehension, the brain processes not only word meanings, but also the grammatical structure—the “syntax”—that strings words into phrases and sentences. Yet the neural basis of syntax remains contentious, partly due to the elusiveness of experimental designs that vary structure independently of meaning-related variables. Here, we exploit Arabic’s grammatical properties, which enable such a design. We collected magnetoencephalography (MEG) data while participants read the same noun-adjective expressions with zero, one, or two contiguously-written definite articles (e.g., ‘chair purple’; ‘the-chair purple’; ‘the-chair the-purple’), representing equivalent concepts, but with different levels of syntactic complexity (respectively, indefinite phrases: ‘a purple chair’; sentences: ‘The chair is purple.’; definite phrases: ‘the purple chair’). We expected regions processing syntax to respond differently to simple versus complex structures. Single-word controls (‘chair’/‘purple’) addressed definiteness-based accounts. In noun-adjective expressions, syntactic complexity only modulated activity in the left posterior temporal lobe (LPTL), ~ 300 ms after each word’s onset: indefinite phrases induced more MEG-measured positive activity. The effects disappeared in single-word tokens, ruling out non-syntactic interpretations. In contrast, left anterior temporal lobe (LATL) activation was driven by meaning. Overall, the results support models implicating the LPTL in structure building and the LATL in early stages of conceptual combination.

Early childhood mental health programs are vital for the current and future mental health and brain development of infants, toddlers, and preschoolers. Founded in 2014, Safe Start is the only early childhood mental health program in Beirut, Lebanon. It aims at being the prototype of such services at the national level. A retrospective analysis of the outcomes of the first year of operations has resulted in important findings about the age of the participants, their diagnoses, previous therapies that the participants have undergone, types of referrals recommended, and the number of participants who were lost to follow-up. This first analysis pointed at the need for more in-depth research to encompass the gaps and benefits of such services. It shows the pivotal importance of designing awareness strategies about the importance of early childhood mental health services and care; to move from a diagnostic seeking behavior to commitment to psychotherapy and follow-up interventions.
