Functional MRI studies have demonstrated that the striatum is clearly involved in biasing action selection in accord with current action values [13], and that activity in this structure changes in accord with ongoing prediction errors [10], [31] [32].
This is accomplished through interactions with the mesolimbic dopamine system which activates in accord with ongoing reward prediction error signals [18].
This indicates that, when behavior is relatively stable, the ventral striatum is engaged to dynamically track ongoing reward estimation errors.
So far, our work continues to be an ongoing process of trial, error, and, most importantly, open discussion.
Given existing alternatives for accurate brachytherapy dosimeters, future requirements will likely be made on in vivo dosimetry systems that can monitor the dose in real time, are sensitive to displacements of all applicators involved in the treatment, can identify organ motion, and that can provide immediate alerts of any potential gross error during ongoing treatments which alerts the clinician.

Investigations to reduce and quantify these additional sources of error are ongoing and will be published in due course.
However, a BMI user has constant visual feedback about the ongoing task and any errors could potentially be reflected in his brain activity.
The fallout from the magazine's errors is ongoing: it's not clear yet whether Jackie, the woman who told Rolling Stone that she was gang-raped, made the story up, told the truth but exaggerated, was so traumatized that her story shifted due to P.T.S.D., or what.
Properly constructed mixture samples can be used to correct for systematic measurement errors, provide ongoing monitoring of performance, serve as a tool for interlaboratory comparison, and create a context for evaluating batch effects, protocols, and informatic analyses.
Ongoing efferent-afferent feedback errors propel a positive feedback loop, resulting in the progressively higher levels of respiratory drive, inspiratory esophageal pressure, and work of breathing reported by others, and it may lead to clinical respiratory distress [ 34, 36].
