Background: This study is based on the hypothesis that functional Magnetic Resonance Imaging (fMRI) indices in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia patients are spatially more heterogeneous than healthy controls for activation evoked ...
Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression in ...
During the last years, the concept of gliotransmission has been established. Glutamate has been shown to be released from astrocytes by different mechanisms, e.g., in an exocytotic manner. The authors have previously shown that astrocytes in the dentate-mo ...
This paper presents a model for the estimation of the repayment process of delinquent credit-card accounts conditional on account-specific and macroeconomic information. Based on this model we construct a dynamic collectability score (DCS). The DCS estimat ...
Optimal behavior relies on flexible adaptation to environmental requirements, notably based on the detection of errors. The impact of error detection on subsequent behavior typically manifests as a slowing down of RTs following errors. Precisely how errors ...
Human subjects are proficient at tracking the mean and variance of rewards and updating these via prediction errors. Here, we addressed whether humans can also learn about higher-order relationships between distinct environmental outcomes, a defining ecolo ...
In this contribution we present multi-channel microinjector arrays fabricated by a reliable three-layer SU-8 process and assembled with glutamate biosensor microprobes1. It enables local delivery of specific liquids into brain tissue for the stimulation or ...
Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...
