The phrase "activation of the brain" is correct and usable in written English.
It can be used in contexts related to neuroscience, psychology, or discussions about cognitive processes and mental states.
Example: "The activation of the brain during meditation has been shown to enhance focus and reduce stress."
Alternatives: "stimulation of the brain" or "engagement of the brain".
Chronic social defeat stress is accompanied by activation of the brain serotonergic system and, presumably, decreased dopaminergic activities [17].
They thought that activation of the brain stem might play a role in the onset of migraine pain.
These results suggest that activation of the brain phospholipase A2-arachidonic acid cascade facilitates the central sympatho-adrenomedullary outflow in rats.
Activation of the brain angiotensin II type 1 receptor (AT1R) triggers pro-oxidant and pro-inflammatory mechanisms which are involved in the neurobiology of bipolar disorder (BD).
The results demonstrated that the meditators generally had enhanced activation of the brain areas involved in emotional processing (such as the amygdala) when viewing both the self-praising and self-critical traits, suggesting that they fully experienced those negative emotions.
The goal is to see how sharing a new and challenging experience with a spouse changes the neural activation of the brain.
Over the last decade stress has been identified as a trigger of gastrointestinal dysfunctions through activation of the brain-gut axis.
Moreover, hypnotic sedation (e.g., midazolam and propofol) does not attenuate pain-related ML-SSEPs (like opioids do), as ML-SSEPs seem to be the neurophysiological expression of the activation of the brain-area network involved both in pain perception [ 11, 32] and other salient sensory input [ 33].
Specific functional activations of the brain can increase the probability of solving problems with insight in tasks with verbal anagrams.
The tendency to use insight strategies can be therefore modulated by individual activation traits [29] as well as by ongoing functional activations of the brain promoting attentional diffusion and right-lateralized hemispheric asymmetry [27] [28].
For example, neurobiologists can track the activation of microglia, the brain's native immune cells, based on their shapes.
