Errare machinale est: the use of error-related potentials in brain-machine interfaces

Frontiers in Neuroscience, Год журнала: 2014, Номер 8

Опубликована: Июль 22, 2014

The ability to recognize errors is crucial for efficient behavior. Numerous studies have identified electrophysiological correlates of error recognition in the human brain (error-related potentials, ErrPs). Consequently, it has been proposed use these signals improve human-computer interaction (HCI) or brain-machine interfacing (BMI). Here, we present a review over decade developments towards this goal. This body work provides consistent evidence that ErrPs can be successfully detected on single-trial basis, and they effectively used both HCI BMI applications. We first describe ErrP phenomenon follow up with an analysis different strategies increase robustness system by incorporating recognition, either correcting machine's actions providing means its error-based adaptation. These approaches applied when user employs traditional input devices combination another channel. Finally, discuss current challenges overcome order fully integrate into practical includes, particular, characterization such during real(istic) applications, as well possibility extracting richer information from them, going beyond time-locked decoding dominates approaches.

Coordinated interactions between the central and autonomic nervous systems are crucial for survival due to inherent propensity human behavior make errors. In our ever-changing environment, when individuals mistakes, these errors can have life-threatening consequences. response errors, specific reactions occur in both brain activity heart rate detect correct Specifically, there two brain-related indicators of error detection awareness known as error-related negativity positivity. Conversely, cardiac deceleration denotes a momentary slowing following an error, signaling response. However, what is connection during processing? this review, we discuss functional neuroanatomical connections markers processing, exploring experimental conditions which they covary. Given current limitations available data, future research will continue investigate neurobiological factors governing brain-heart interaction, aiming utilize them combined assessing cognitive control healthy pathological conditions.

Neural evidence accumulation persists after choice to inform metacognitive judgments

eLife, Год журнала: 2015, Номер 4

Опубликована: Дек. 19, 2015

The ability to revise one’s certainty or confidence in a preceding choice is critical feature of adaptive decision-making but the neural mechanisms underpinning this metacognitive process have yet be characterized. In present study, we demonstrate that same build-to-threshold decision variable signal triggers an initial continues evolve after commitment, and determines timing accuracy self-initiated error detection reports by selectively representing accumulated evidence was incorrect. We also show peri-choice generated medial frontal cortex provides source input post-decision accumulation process, indicating judgments are not solely based on feedforward sensory evidence. These findings impart novel insights into generative metacognition.

Error-related potentials during continuous feedback: using EEG to detect errors of different type and severity

Frontiers in Human Neuroscience, Год журнала: 2015, Номер 9

Опубликована: Март 26, 2015

When a person recognizes an error during task, error-related potential (ErrP) can be measured as response. It has been shown that ErrPs automatically detected in tasks with time-discrete feedback, which is widely applied the field of Brain-Computer Interfaces (BCIs) for correction or adaptation. However, there are only few studies concentrate on continuous feedback. With this study, we wanted to answer three different questions: (i) Can electroencephalography (EEG) recordings task cursor control? (ii) classified using machine learning methods and it possible discriminate errors origins? (iii) use EEG detect severity error? To these questions, recorded data from 10 subjects video game investigated two types (execution error, due inaccurate feedback; outcome not achieving goal action). We analyzed show same kinds produce ErrP waveforms have spectral This allows us origin event-locked manner. By utilizing response, also continuous, asynchronous detection possible. Although based was one did find any significant influence EEG.

The specific role of serotonin and its interplay with dopamine (DA) in adaptive, reward guided behavior as well drug dependance, still remains elusive. Recently, novel methods allowed cell type anatomical, functional interventional analyses serotonergic dopaminergic circuits, promising significant advancement understanding their roles. Furthermore, it is increasingly recognized that co-release neurotransmitters functionally relevant, which required order to interpret results pharmacological studies relationship neural recordings. Here, we review recent animal employing such techniques the aim connect effects observed human subjective drugs. It appears additive effect DA conveys related information subjectively highly euphorizing. Neither nor alone have an effect. This coincides optogenetically targeted recordings mice, where system codes prediction errors (PE), mainly unsigned PE. Overall, this pattern indicates joint activity between both systems carries essential invites parallel investigation neurotransmitter systems.

Trait Extraversion and Dopamine Function

Social and Personality Psychology Compass, Год журнала: 2015, Номер 9(6), С. 225 - 238

Опубликована: Июнь 1, 2015

Abstract An influential theory within personality neuroscience suggests that trait extraversion is underpinned by individual differences in dopamine function. In a review of the relevant literature, we evaluate this light evidence from molecular genetics, neuroimaging, and psychopharmacology. Evidence linking with dopamine‐relevant genes, structural volume dopamine‐rich brain regions (e.g., striatal ventral prefrontal areas), receptor availability, frontal alpha asymmetry mixed at best. concerning both scalp recorded (electroencephalogram) hemodynamic (functional magnetic resonance imaging) neural responses to rewards appears somewhat more promising. Perhaps best concerns extraversion‐dependent – behavioural dopaminergic drugs. Future research area must go beyond demonstration theoretically consistent associations attempt provide specific causal for hypothesis extraversion. A further challenge expand incorporate other neurobiological processes are likely underlie trait.

PLoS Computational Biology, Год журнала: 2016, Номер 12(6), С. e1004953 - e1004953

Опубликована: Июнь 20, 2016

Adolescence is a period of life characterised by changes in learning and decision-making. Learning decision-making do not rely on unitary system, but instead require the coordination different cognitive processes that can be mathematically formalised as dissociable computational modules. Here, we aimed to trace developmental time-course modules responsible for from reward or punishment, counterfactual feedback. Adolescents adults carried out novel reinforcement paradigm which participants learned association between cues probabilistic outcomes, where outcomes differed valence (reward versus punishment) feedback was either partial complete (either outcome chosen option only, both unchosen option, were displayed). Computational strategies changed during development: whereas adolescents' behaviour better explained basic algorithm, adults' integrated increasingly complex features, namely module (enabling enhanced performance presence feedback) value contextualisation symmetrical punishment learning). Unlike adults, adolescent did benefit (complete) In addition, while symmetrically adolescents less likely learn punishment. This tendency rewards consider alternative consequences actions might contribute our understanding adolescence.
