Negation is a fundamental operation in human reasoning and communication and is universally present in all natural languages. Its ability to reverse the truth value polarity of declarative statements and to set in contrast factual and counterfactual states of affairs, poses unique and challenging demands to cognitive and brain resources. Behavioural, neuroimaging, and neuromodulation experiments have provided remarkable insights into the involved neurocognitive mechanisms. However, they have also led to conflicting evidence speaking for the reduced accessibility of conceptual-semantic representations under the scope of negation, for neural inhibition, for increased processing complexity, and for either immediate or delayed integration of negation polarity information in sentence meaning. Here, we will review and discuss the key experimental findings on negation. Subsequently, we will attempt to integrate and reconcile the available evidence by advancing a new, so-called Disengagement Model of Linguistic Negation, which accounts for the orchestrated interaction between multiple large-scale brain networks. It will be argued that the mutual reinforcement or inhibition between the cognitive control network, on the one side, and the core language network and experientially grounded conceptual-semantic system, on the other side, provides a parsimonious and efficient mechanism for semantic composition, and permits the disengagement of neurocognitive resources required for the final integration of negation into sentence meaning.
