HUMAN PROCESSING OF BEHAVIORALLY RELEVANT AND IRRELEVANT ABSENCE OF EXPECTED REWARDS: A HIGH-RESOLUTION ERP STUDY.

Human processing of behaviorally relevant and irrelevant absence of expected rewards: a high-resolution ERP study.

Acute lesions of the posterior medial orbitofrontal cortex (OFC) in humans may induce a state of reality confusion marked by confabulation, disorientation, and currently inappropriate actions.This clinical state is strongly associated with an inability to abandon previously valid anticipations, that is, extinction capacity.In healthy subjects, the

Preserving inferior right hepatic vein enabled bisegmentectomy 7 and 8 without venous congestion: a case report

Abstract Background In hepatectomy, the preservation of portal perfusion and venous drainage in the remnant liver is important for securing postoperative hepatic function.Right hepatectomy is generally indicated when a hepatic tumor involves the right hepatic vein (RHV).However, if a sizable inferior RHV (IRHV) exists, hepatectomy with preservation

Expectation-Maximization via Pretext-Invariant Representations

Contrastive learning methods have been widely adopted in numerous unsupervised and self-supervised visual representation learning methods.Such algorithms aim to maximize the cosine similarity between two positive samples while minimizing that of the negative samples.Recently, Grill et al.propose an algorithm, BYOL, to utilize only positive samples,

Exploring neuronal bistability at the depolarization block.

Many neurons display bistability--coexistence of two firing modes such as bursting and tonic spiking or tonic spiking and silence.Bistability Your Heart has been proposed to endow neurons with richer forms of information processing in general and to be involved in short-term memory in particular by allowing a brief signal to elicit long-lasting cha
