Когнитивный контроль: новые мозговые механизмы, выявленные с помощью частотно-временного анализа электроэнцефалограммы при выполнении экспериментальной задачи с высокой нагрузкой на внимание
С. 393–397.
Cognitive control includes specific maintenance of sustained attention to a stimulus
and non-specific regulation of a motor threshold. Failures in each system lead to different
types of errors, associated with attentional lapses and uncertainty or dysfunction of
the motor threshold. Subsequent adaptive adjustments can be implemented through two
different mechanisms, depending on the type of error. Two experiments were conducted using
the auditory condensation task, which is highly demanding for sustained attention. We
analyzed EEG oscillations in theta, alpha and beta bands. The results indicate that adaptive
adjustments after errors are implemented by the frontal-medial network of task monitoring,
the parietal attentional network and the sensorimotor network. Moreover, we discovered
that response times may serve as an efficiency marker of each network, which allows us to
distinguish between two types of responses: fast responses with a high level of attention
and low level of uncertainty, and slow responses with a low level of attention and high level
of uncertainty. Jointly, the results of both experiments demonstrate that the condensation
task in an auditory modality is a new prospective method for investigating the brain mechanisms
of cognitive control.
