“…The medial portion of the superior frontal gyrus has been found activated during the monitoring of conflicts (Ridderinkhof et al, 2004), and in particular when evaluating sentences that were conflicting and ambiguous (Ye and Zhou, 2009). In the present study, divergent thinkers may have noticed conflicts between previously encoded A-B and currently processed B-C pairs.…”

Relational inference denotes the capacity to encode, flexibly retrieve, and integrate multiple memories to combine past experiences to update knowledge and improve decision-making in new situations. Although relational inference is thought to depend on the hippocampus and consciousness, we now show in young, healthy men that it may occur outside consciousness but still recruits the hippocampus. In temporally distinct and unique subliminal episodes, we presented word pairs that either overlapped ("winter-red", "red-computer") or not. Effects of unconscious relational inference emerged in reaction times recorded during unconscious encoding and in the outcome of decisions made 1 min later at test, when participants judged the semantic relatedness of two supraliminal words. These words were either episodically related through a common word ("winter-computer" related through "red") or unrelated. Hippocampal activity increased during the unconscious encoding of overlapping versus nonoverlapping word pairs and during the unconscious retrieval of episodically related versus unrelated words. Furthermore, hippocampal activity during unconscious encoding predicted the outcome of decisions made at test. Hence, unconscious inference may influence decision-making in new situations.

“…Extensive evidence has linked pars orbitalis with increasing demands on semantic retrieval in the context of conflict (e.g., Badre and Wagner 2007;Ye and Zhou 2009;Nosarti et al 2010). Pseudowords may also heavily recruit related semantic representations because of a more prolonged search for the missing meaning (Mechelli et al 2003).…”

“…Sentence-level semantic analysis involves several regions involved in speech perception, including the bilateral middle temporal gyrus, the angular gyrus, and often Broca's area (Mashal et al, 2009;Obleser and Kotz, 2009;Rogalsky and Hickok, 2009;Ye and Zhou, 2009;Price, 2010). Phonological processing-the production of an auditory representation of linguistic contentrequires several subprocesses, only a fraction of which are specific to reading, such as grapheme-to-phoneme conversion in the left ventral temporal occipital cortex (Cohen et al, 2000).…”

Reading sentences involves a distributed network of brain regions acting in concert surrounding the left sylvian fissure. The mechanisms of neural communication underlying the extraction and integration of verbal information across subcomponents of this reading network are still largely unknown. We recorded intracranial EEG activity in 12 epileptic human patients performing natural sentence reading and analyzed long-range corticocortical interactions between local neural activations. During a simple task contrasting semantic, phonological, and purely visual processes, we found process-specific neural activity elicited at the single-trial level, characterized by energy increases in a broad gamma band (40 -150 Hz). Correlation analysis between task-induced gamma-band activations revealed a selective fragmentation of the network into specialized subnetworks supporting sentence-level semantic analysis and phonological processing. We extend the implications of our results beyond reading, to propose that gamma-band amplitude correlations might constitute a fundamental mechanism for large-scale neural integration during high-level cognition.
