The phrase "alter activity" is correct and usable in written English.
It can be used when discussing changes or modifications to a specific action or task.
Example: "To improve efficiency, we need to alter activity in our workflow to better align with our goals."
Alternatives: "modify action" or "change task".
When activated by nAChR stimulation, interneurons can alter activity and plasticity in pyramidal neurons (Xiang et al. 1998; Alkondon et al. 2000; Ji and Dani 2000; Ji et al. 2001; Couey et al. 2007).
It has been shown that negative environmental cues might differentially alter activity in brain regions related to emotional processing: Amygdala and hippocampus activation at rest was correlated positively with life stress in carriers of the S-allele, but negatively in LL-genotypes (Canli and Lesch 2007).
To investigate the underlying mechanistic basis by which the alterations in the sequence and conformation of the TGF-βs might alter activity, the binding properties of TGF-β313, TGF-β131, and TGF-β3H4 for the signaling receptors, TβRI and TβRII, were investigated using SPR.
For instance, it might be possible to find drugs that specifically alter activity in the regions in question; alternatively, non-invasive brain stimulation could help correct any abnormal circuits – preventing the 'error network' from going into overdrive.
Even mutating both Ser552 and Ser554 to Ala did not alter activity significantly.
Silioxanes identified by GC-MS could alter activity of enzymes through specific or non-specific interactions.
A dose of the psychedelic substance – injected rather than dropped – unleashed a wave of changes that altered activity and connectivity across the brain.
Is there altered activity of the extensor muscles in chronic mechanical neck pain?
The combined approaches of rational design and random mutagenesis were applied to generate a sesquiterpene synthase with an altered activity.
Sertraline treatment prevented increases in body weight, fat, insulin, and HOMA-IR (all p < 0.05), without significantly altering activity levels.
Increasing evidence shows that altered activity of MTases may cause aberrant DNA methylation, which in turn may lead to malignant transformation, and ultimately to cancer.
