Decreased brain coordinated activity in autism spectrum disorders during executive tasks: reduced long-range synchronization in the fronto-parietal networks.

20 May 2009 Current theories of brain function propose that the coordinated integration of transient activity patterns in distinct brain regions is the essence of brain information processing. The behavioural manifestations of individuals with autism spectrum ...

Neural correlates of depth of strategic reasoning in medial prefrontal cortex.

20 May 2009 We used functional MRI (fMRI) to investigate human mental processes in a competitive interactive setting--the "beauty contest" game. This game is well-suited for investigating whether and how a player's mental processing incorporates the thinking ...

Optimal integration of gravity in trajectory planning of vertical pointing movements.

18 May 2009 The planning and control of motor actions requires knowledge of the dynamics of the controlled limb to generate the appropriate muscular commands and achieve the desired goal. Such planning and control imply that the CNS must be able to deal with ...

Aging extends the time required to switch cognitive set.

17 May 2009 The Attentional Blink (AB) refers to a decrease in the chance of detecting a second target in a rapid sequence of items if it occurs within approximately 500 ms of a first target. In this study the efficiency of establishing and switching cognitive ...

Oscillatory EEG correlates of arithmetic strategy use in addition and subtraction.

17 May 2009 Adults use different strategies in mental arithmetic. For example, they directly retrieve the answer from memory or calculate by means of procedural strategies. Despite growing insight into the hemodynamic and electrophysiological correlates of ...

Prefrontal cortex and the evolution of symbolic reference.

13 May 2009 Symbol systems such as numbers and language are of paramount importance to human cognition. In number theory, numbers are symbolic signs embedded in a system of higher-order sign-sign relations. During ontogeny, numerical competence passes through ...

Why the brain talks to itself: sources of error in emotional prediction.

10 May 2009 People typically choose pleasure over pain. But how do they know which of these their choices will entail? The brain generates mental simulations (previews) of future events, which produce affective reactions (premotions), which are then used as a ...

Recruitment of an area involved in eye movements during mental arithmetic.

5 May 2009 Throughout the history of mathematics, concepts of number and space have been tightly intertwined. We tested the hypothesis that cortical circuits for spatial attention contribute to mental arithmetic in humans. We trained a multivariate classifier ...

Cortical activity prior to predictable postural instability: is there a difference between self-initiated and externally-initiated perturbations?

3 May 2009 Previous work has revealed pre-perturbation cortical activity linked to predictably-timed perturbations to upright stability. Because individuals rely on the ability to anticipate perturbations for independent mobility, we sought to determine ...

The acute effect of low-dose alcohol on working memory during mental arithmetic: II. Changes of nonlinear and linear EEG-complexity in the theta band, heart rate and electrodermal activity.

May 2009 OBJECTIVE AND HYPOTHESIS: Nonlinear and linear methods of EEG-complexity analysis and autonomic measures were used to characterize processes accompanying performance in a mental arithmetic task challenged by low ("social") alcohol doses. It was ...
