Differential roles for parietal and frontal cortices in fixed versus evolving temporal expectations: Dissociating prior from posterior temporal probabilities with fMRI

Jennifer T. Coull, Julien Cotti, Franck Vidal
2016 NeuroImage  
Temporal predictability can be either fixed (prior probability) or evolving (posterior probability), in which case it is dynamically updated as a function of the elapse of time itself ("hazard function  ...  Our data highlight a key role for left parietal cortex in instantiating the behavioural benefits of temporal predictability, whether predictions are fixed or dynamically evolving. (270 words)  ...  These data appeared in abstract form in Coull JT, Cotti J, Vidal F (2014) Increasing activity in left inferior parietal cortex and right prefrontal cortex with increasing temporal predictability: An fMRI  ...

Instructed Delay Activity in the Human Prefrontal Cortex is Modulated by Monetary Reward Expectation

N. Ramnani
2003 Cerebral Cortex  
The latter two areas appear to be frontal systems integrating the expectation of rewards with selection and preparation of actions.  ...  Goal-directed actions are executed with greater efficiency when the goals of the actions are rewarded and so the reward expectation must influence systems concerned with action-planning and motor control  ...  Notes This work was supported by grants to RCM from the James McDonnell Foundation and the Wellcome Trust, and to Prof. Paul M.  ...

The chronometry of risk processing in the human cortex

Mkael Symmonds
2013 Frontiers in Neuroscience  
Consequently, here we address the temporal evolution of neural activity related to encoding of risk using magnetoencephalography (MEG), and show modulations of electromagnetic power in posterior parietal  ...  The observation that cortical activity tracks specific and independent components of risk from early time-points in a decision-making task supports the hypothesis that specialized brain circuitry underpins  ...  The early effect occurs concurrently with risk encoding in parietal and prefrontal cortices, indicating a possible role in a risk-processing network.  ...

Acknowledgements The authors wish to thank Christiane Wolf for her help in acquiring the data. This work was supported by the DFG (grant number WE 4156/2-1).  ...  For this purpose he applied a source montage on the MEG data consisting of 8 fixed regional sources each at a prominent location of the cortex (ACC, PCC, left and right frontal, temporal and parietal)  ...  While posterior recording sites have been the regions of interest in many studies, we focus on recordings from temporal and frontal regions, which we believe are mainly involved in the psychoacoustic and  ...

A Neuropsychological Approach to Understanding Risk-Taking for Potential Gains and Losses

Irwin P. Levin, Gui Xue, Joshua A. Weller, Martin Reimann, Marco Lauriola, Antoine Bechara
2012 Frontiers in Neuroscience  
Taken together, these studies support a clear functional dissociation between risk-taking for gains and risk-taking for losses, and further dissociation at the neural level.  ...  Included are studies using patients with lesions to brain areas specified as important in the model and studies with healthy individuals whose brains are scanned to reveal activation in these and other  ...  for gains versus losses Nucleus accumbens Caudate tail Middle occipital gyrus Losses (safe minus risky responses) Superior temporal gyrus Middle temporal gyrus Inferior frontal gyrus  ...

Distinct neural networks relate to common and speaker-specific language priors

Leon O H Kroczek, Thomas C Gunter
2020 Cerebral Cortex Communications  
We observed distinct neural processing for syntactic complexity and speaker-specific language use. Syntactic complexity correlated with left frontal and posterior temporal regions.  ...  Finally, the top-down influence of speaker information was found in frontal and striatal brain regions, suggesting a mechanism for controlled syntactic processing.  ...  There was higher-than-chance decoding accuracy in the frontal pole as well as medial frontal and parietal lobe (see Supplementary Material ).  ...

Neural Substrates of Muscle Co-contraction during Dynamic Motor Adaptation

Saeed Babadi, Shahabeddin Vahdat, Theodore E. Milner
2021 Journal of Neuroscience  
A neural link between cerebellum, superior frontal gyrus and motor cortical regions was associated with reduction of co-contraction during later stages of adaptation.  ...  Using resting-state fMRI analysis we demonstrate that a distributed cerebellar-parietal-frontal network functions to regulate muscle co-contraction with the cerebellum as its key component.  ...  A regressor for arm movement versus rest condition was modeled with a boxcar function with the temporal derivative of the stimulation timing as an additional regressor.  ...
