DAC-X supports complex foraging strategies through the progressive acquisition, retention and expression of task-dependent information and associated shaping of action, from exploration to goal-oriented deliberation.
While TASK-3, the closest relative of TASK-1, was previously not described in cardiac tissue, we found a very prominent expression of TASK-3 in right human auricles.
Importantly, this effect did not rely on the use of ribosome-tethered precursors that might favour N-terminal translocation (the present study, and [ 6]), and was also observed following the in vivo expression of TASK-1 derivatives in mammalian cells.
Nevertheless, the combination of our genetic data, the newly identified preferential expression of TASK-4 in the conduction system, together with the strong electrophysiological phenotype that we have identified, clearly suggests that the G88R mutation is a disease-modifying mutation for PCCD.
The expression of TASK-4 in Purkinje fibers was as high as for the K2P channel TASK-1 (KCNK3), which is known to be preferentially expressed in the conduction system of mouse and chick hearts (Fig 3B) (Graham et al, 2006).
As already mentioned, a correlation was observed between the severity of the phenotype of TaSKs.2-1 lines and expression levels of TaSKs (Fig. 2a, e, i; Additional file 1, A).
As a result, the association of foraging expression with task behavior within a species changes depending on the time of day the individuals are sampled.
The classifier performance values were submitted to a three-way anova of task (expression or gender), region (eyes, mouth or rest-of-V1) and classification (expression or gender), and revealed a significant effect of region (F1,8 = 4.89, P = 0.02); overall decoding performance was higher in the rest of V1 than either of the diagnostic patches.
Surface expression of HA-tagged TASK-4 channel constructs was analyzed in Xenopus oocytes.
Cyclic expression of period is task-specific; foragers have strong daily fluctuations but nest workers inside the nest do not.
Section 5.3 describes in a simulation the effect of lesioning these connections on the learning and expression of three motor tasks.
