Collinearity: a review of methods to deal with it and a simulation study evaluating their performance

Collinearity refers to the non independence of predictor variables, usually in a regression‐type analysis. It is a common feature of any descriptive ecological data set and can ...

A Neural Substrate of Prediction and Reward

The capacity to predict future events permits a creature to detect, model, and manipulate the causal structure of its interactions with its environment. Behavioral experiments s...

Responses of monkey dopamine neurons to reward and conditioned stimuli during successive steps of learning a delayed response task

The present investigation had two aims: (1) to study responses of dopamine neurons to stimuli with attentional and motivational significance during several steps of learning a b...

Preferential activation of midbrain dopamine neurons by appetitive rather than aversive stimuli

Importance of unpredictability for reward responses in primate dopamine neurons

1. We used single neuron recording techniques in two behaving monkeys to investigate the conditions in which dopamine neurons respond to primary rewarding or potentially rewardi...

Hydrogen in the mechanically prepared nanostructured graphite

Nanostructured graphite was prepared by mechanical milling under hydrogen atmosphere. Several samples obtained after different milling times were systematically examined to get ...
