We demonstrate an alteration in task-modulated connectivity in a region of frontal cortex directly connected to the thalamus via the same anatomical bundle, and overlapping with the supplementary motor area.
In addition, thalamic inhibition of the supplementary motor area and premotor cortex has been shown to be decreased in association with reduced structural connectivity within thalamo-cortical motor control circuits, which leads to alteration of task-modulated functional connectivity with subsequent impairment of frontal lobe functions (O'Muircheartaigh et al., 2012).
Therefore, exploring the alterations in task-related DMN deactivation and functional connectivity that affect episodic memory in T2DM will help to enhance our understanding of the allocation patterns underlying memory function in T2DM.
However, in spite of this pharmacological attribute, the authors demonstrated that TRPM8-expressing neurons of the DRG can be activated by Zn2+, presumably caused by alterations in TASK-3 potassium (K+) leak channel activity.
It has previously been shown that peripheral impairments are generally more pronounced after shorter high-intensity tasks, whereas central alterations increase with task duration (Amann 2011; Nybo 2008).
In the literature, one can observe that several walking variables, and not one alone, can reveal an alteration in dual-task locomotor performance.
This alteration seems to be task-dependent and varies depending on the nature and timing of the stimulation.
In addition to showing deficits in behavioral task performance, alterations in home-cage activity have also been noted in different strains of Mecp2-deficient mice (19, 36).
Therefore, the selection of the putative mutation carriers as well as the detection of the causative germline alterations is a challenging task.
This work stems from a previous study in which alterations in the task-negative default mode network were investigated.
As a model for human trisomy 21, these mice display many attractive features, including performance deficits in different behavioral tasks, alterations in synaptic plasticity and adult neurogenesis, motor dysfunction, and age-dependent cholinergic neurodegeneration.
