Using this task paradigm, we found that neurons in area CA1 of the hippocampus and in the entorhinal cortex exhibit task-relevant spatiotemporal coding, which (we speculate) could be used by other brain regions to guide task behavior.
Relative to those with low amyloid burden, older adults with substantial amyloid burden showed atypical activity in regions associated with the default network that typically exhibit task-related reductions of activity (Shulman et al. 1997; Mazoyer et al. 2001; for review, see Buckner et al. 2008 and Raichle et al. 2001).
The GPU framework of BLAZE-DEM is limited to applications that require large numbers of particles with simplified interactions such as hopper flow which exhibits task level parallelism that can be exploited on the GPU.
These brain-wide functional connectivity analyses identified the rACC as a region exhibiting task-related connectivity (puncorrected<0.005, k>5) with two or more seed regions, particularly for justice issue processing, and was thus entered as a component of the path model for effective connectivity analysis.
All 29 serotonergic neurons exhibited task-related modulations in firing rate (ANOVA, all p < 0.01).
Interestingly, a recent study that also examined theta oscillations in the Sternberg task reported a general lack of coherence between distant electrodes exhibiting task-modulated theta oscillations, suggesting that these recordings are sensitive to activity largely of local origin (Raghavachari et al. 2006).
Eusocial species often exhibit extreme task specialization, which makes colonies potentially very efficient in gathering resources.
We predict that quinpirole-treated rats would, therefore, exhibit lower task success if they were tested under conditions that prevented normal checking behaviour.
However, the females exhibited increased task accuracy only after the highest dose.
The advent of multi- and many-core processors offers enormous performance potential for parallel tasks that exhibit sufficient intra-task thread-level parallelism.
