Fig. 3. From: Task-specific change of unconscious neural priming in the cerebral language network.

Neural priming in the premotor cortex. The left PMv (green) exhibited repetition enhancement during reading, whereas the PMd (blue) showed repetition suppression during categorization across the four priming conditions.

Experimental paradigm and behavioral results. (A) Sequence of events used for the behavioral tasks. Participants either read aloud visible targets or categorized them as representing natural or artificial objects. (B) Mean reaction times (±SEM) during reading and categorization.

Fig. 2. From: Task-specific change of unconscious neural priming in the cerebral language network.

Neural priming in the left parietotemporal cortex. Global priming effects (green blobs) were significant in the left IPL and posterior FG for reading and in the left MTG for categorization (shadowed in dark gray). The left posterior MTG (blue blob) exhibited cross-script repetition enhancement during reading (in light gray). Bars represent the mean percent signal change (±SEM) for each condition relative to the baseline.

Fig. 5. From: Task-specific change of unconscious neural priming in the cerebral language network.

Neurocognitive components of unconscious repetition priming. The left FG receiving the visual input is associated with abstract, shape-invariant representations of pronounceable letter-strings (). The ventral stream from the FG, comprising the IPL for print-to-sound translation and PMv for speech planning (dark gray), operates in the generation of subliminal priming during reading aloud. In contrast, the dorsal stream from the left FG, comprising the MTG for semantic representations and PMd for manual response preparation (light gray), is involved in repetition priming during categorization.

Fig. 4. From: Task-specific change of unconscious neural priming in the cerebral language network.

Contextual effects on the task-specific neural pathways. (A) The influence of task set over the neural circuitry involved in reading aloud. Spoken word production relies on distributed forward and backward connections in the left hemisphere, whereas categorization partially recruits the same network (Upper). The task-context exerts a differential impact at the reciprocal STG-IPL connections and the PMv-STG projection (Lower). (B) The influence of task set over the neural circuitry involved in categorization. The left FG was involved in reciprocal couplings with PMd and MTG during categorization. These two structures received excitatory input from STG during both reading and categorization. However, none of these connections differed in coupling strength between the two tasks.
