The phrase "a functional coupling between" is correct and usable in written English.
It can be used in contexts discussing relationships or interactions between systems, components, or concepts, particularly in scientific or technical writing.
Example: "The study revealed a functional coupling between the two neural networks, suggesting they work together to process information."
Alternatives: "a functional link between" or "an operational connection between".
The overstimulation of glutamate receptors as a consequence of COX-2 gene deletion suggests a functional coupling between COX-2 and the glutamatergic system.
In order to assess a functional coupling between COX2 and AKR1B7, we stably transfected plasmids encoding these two enzymes into the HEK293 cell line that is known to be devoid of COX activity [32] (Fig. 3A, B).
Although gamma oscillations are thought to transiently link local cell assemblies processing closely related information [43], the widespread increase in cortical gamma band activity with theta-tDCS supports a functional coupling between these rhythms, with the theta rhythm presumably serving to synchronize gamma band activity occurring at distant regions and/or increase its coherence.
Therefore, our studies predict a functional coupling between these two activities.
We therefore investigated whether there could be a functional coupling between Cav3.2 and BK channels in the plasma membrane.
Also, we have confirmed a functional coupling between mitochondria and a fraction of ATPases in the cell.
Our data clearly suggest that in PASMCs mitochondria are spatially arranged in the distinctive layer separate from the SR, forming a compartment with restricted diffusion in the subplasmalemmal space, thus providing a structural basis for a better functional coupling between mitochondria and Kv channels in PASMCs than in systemic arterial myocytes.
These results however do not completely rule out a tight functional coupling between STS and a yet unknown E3S transport system.
The data indicate a strong functional coupling between the side chains of T203 and Y206, with a coupling strength of 2.1 kcal/mol (Table 3), between the T203A and Y206F mutants.
These results highlight that there is a functional coupling in LNCaP cells between BK channels and Cav3.2 channels and that this coupling may participate in prostate cancer cell growth.
Together, these findings demonstrate a strong functional coupling between visual word form areas and sensorimotor representations in the cortex of proficient adult readers.
