AB  - According to the literature, negations such as “not” or “don’t” reduce the accessibility in memory of the concepts under their scope. Moreover, negations applied to action contents (e.g., “don’t write the letter”) impede the activation of motor processes in the brain, inducing “disembodied” representations. These facts provide important information on the behavioral and neural consequences of negations. However, how negations themselves are processed in the brain is still poorly understood. In two electrophysiological experi-ments, we explored whether sentential negation shares neural mechanisms with action monitoring or inhibition. Human participants read action-related sentences in affirmative or negative form (“now you will cut the bread” vs “now you will not cut the bread”) while performing a simultaneous Go/NoGo task. The analysis of the EEG rhythms revealed that theta oscillations were significantly reduced for NoGo trials in the context of negative sentences compared with affirmative sentences. Given the fact that theta oscillations are often considered as neural markers of response inhibition processes, their modulation by negative sentences strongly suggests that negation uses neural resources of response inhibition. We propose a new approach that views the syntactic operator of negation as relying on the neural machinery of high-order action-monitoring processes.
