What drives our curiosity remains an elusive and hotly debated issue, with multiple hypotheses proposed but a cohesive account yet to be established. This review discusses traditional emergent theories that frame as desire know drive learn, respectively. We adopt model-based approach maps the temporal dynamics of various factors underlying curiosity-based exploration, such uncertainty, information gain, learning progress. In so doing, we identify limitations past posit integrated harnesses their strengths in describing tool for optimal environmental exploration. unified account, serves 'common currency' which must balanced other safety hunger achieve efficient action.

Goal commitment is supported by vmPFC through selective attention

Nature Human Behaviour, Год журнала: 2024, Номер unknown

Опубликована: Апрель 17, 2024

When striking a balance between commitment to goal and flexibility in the face of better options, people often demonstrate strong perseveration. Here, using functional MRI (n = 30) lesion patient 26) studies, we argue that ventromedial prefrontal cortex (vmPFC) drives linked changes goal-directed selective attention. Participants performed an incremental pursuit task involving sequential decisions persisting with versus abandoning progress for alternative options. Individuals stronger perseveration showed higher attention interleaved task. Increasing also affected abandonment decisions: while pursuing goal, lost their sensitivity valuable goals remaining more sensitive current goal. In healthy population, individual differences both biases goal-oriented were predicted by baseline goal-related activity vmPFC. Among patients, vmPFC damage reduced commitment, leading performance benefit.

Fundamental processes in sensorimotor learning: Reasoning, refinement, and retrieval

Motor learning is often viewed as a unitary process that operates outside of conscious awareness. This perspective has led to the development sophisticated models designed elucidate mechanisms implicit sensorimotor learning. In this review, we argue for broader perspective, emphasizing contribution explicit strategies tasks. Furthermore, propose theoretical framework motor consists three fundamental processes: reasoning, understanding action–outcome relationships; refinement, optimizing and cognitive parameters achieve goals; retrieval, inferring context recalling control policy. We anticipate ‘3R’ how complex movements are learned will open exciting avenues future research at intersection between cognition action.

Neurocomputational model of compulsivity: deviating from an uncertain goal-directed system

Brain, Год журнала: 2024, Номер 147(6), С. 2230 - 2244

Despite a theory that an imbalance in goal-directed versus habitual systems serve as building blocks of compulsions, research has yet to delineate how this occurs during arbitration between the two obsessive-compulsive disorder. Inspired by brain model which inferior frontal cortex selectively gates putamen guide or actions, study aimed examine whether disruptions process via fronto-striatal circuit would underlie imbalanced decision-making and compulsions patients. Thirty patients with disorder [mean (standard deviation) age = 26.93 (6.23) years, 12 females (40%)] 30 healthy controls 24.97 (4.72) 17 (57%)] underwent functional MRI scans while performing two-step Markov decision task, was designed dissociate behaviour from behaviour. We employed neurocomputational account for uncertainty-based process, prefrontal arbitrator (i.e. gyrus) allocates behavioural control more reliable strategy gating putamen. analysed group differences neural estimates uncertainty each strategy. also compared psychophysiological interaction effects system preference (goal-directed habitual) on coupling groups. examined correlation compulsivity score activity connectivity involved process. The computational captured subjects' preferences strategies. Compared controls, had stronger (t -2.88, P 0.006), attributed uncertain 2.72, 0.009).

When reorienting behaviours reach specific goals, weaker right ipsilateral ventrolateral prefronto-putamen than This hypoconnectivity correlated severe (r -0.57, 0.002). Our findings suggest attenuated top-down underlies Enhancing may be potential neurotherapeutic approach adaptive decision-making.
