In spite of its familiar phenomenology, the mechanistic basis for mental effort remains poorly understood. Although most researchers agree that is aversive and stems from limitations in our capacity to exercise cognitive control, it unclear what gives rise those why they result an experience control as costly. The presence these costs also raises further questions regarding how best allocate minimize maximize attendant benefits. This review explores recent advances computational modeling empirical research aimed at addressing level psychological process neural mechanism, examining both exertion we manage limited resources. We conclude by identifying remaining challenges theoretical accounts well possible applications available findings understanding causes potential solutions apparent failures exert required us.

The frontoparietal network: function, electrophysiology, and importance of individual precision mapping

Dialogues in Clinical Neuroscience, Год журнала: 2018, Номер 20(2), С. 133 - 140

The frontoparietal network is critical for our ability to coordinate behavior in a rapid, accurate, and flexible goal-driven manner. In this review, we outline support the framing of as distinct control network, part functioning flexibly interact with alter other functional brain networks. This coordination likely occurs 4 Hz 73 θ/α rhythm, both during resting state task state. Precision mapping individual human brains has revealed that topography variable between individuals, underscoring notion group-average studies may be obscuring important typical atypical features. Many forms psychopathology implicate such schizophrenia attention-deficit/hyperactivity disorder. Given interindividual variability organization, clinical will benefit greatly from acquiring more subject data accurately characterize resting-state networks compromised psychopathology.La red fronto-parietal es fundamental para nuestra capacidad de coordinar la conducta orientada hacia un objetivo una manera rápida, precisa y flexible.

EEG-Neurofeedback as a Tool to Modulate Cognition and Behavior: A Review Tutorial

Frontiers in Human Neuroscience, Год журнала: 2017, Номер 11

Опубликована: Фев. 22, 2017

Neurofeedback is attracting renewed interest as a method to self-regulate one’s own brain activity directly alter the underlying neural mechanisms of cognition and behaviour. It promises new avenues for cognitive enhancement in healthy subjects, but also therapeutic tool. In current article, we present review tutorial discussing key aspects relevant development EEG neurofeedback studies. addition, putative learning are considered. We highlight both practical application well rather theoretical considerations related generation protocols. Important characteristics regarding set-up protocol outlined step-by-step way. All these illustrated based on results frontal-midline theta up-regulation training improvement executive functions. Not least, assessment criteria validation studies general guidelines evaluation efficacy discussed.

Spontaneous cortical activity transiently organises into frequency specific phase-coupling networks

Nature Communications, Год журнала: 2018, Номер 9(1)

Опубликована: Июль 24, 2018

Frequency-specific oscillations and phase-coupling of neuronal populations are essential mechanisms for the coordination activity between brain areas during cognitive tasks. Therefore, ongoing ascribed to different functional networks should also be able reorganise coordinate via similar mechanisms. We develop a novel method identifying large-scale phase-coupled network dynamics show that resting in magnetoencephalography well characterised by visits short-lived transient states, with spatially distinct patterns oscillatory power coherence specific frequency bands. Brain states identified sensory, motor higher-order networks. The include posterior alpha (8-12 Hz) an anterior delta/theta range (1-7 network, both exhibiting high correspond subdivisions default mode network. Our results cortical have characteristic signatures very bands, possibly reflecting specialisation at intrinsic timescales.
