The phrase "ascending activity" is correct and usable in written English.
It can be used to describe an increase in the level or intensity of an activity over time.
Example: "The data showed an ascending activity in user engagement throughout the campaign."
Alternatives: "increasing activity" or "rising activity".
Interaction of ascending activity with ongoing activity of dense local networks may contribute to multiple brain rhythms, which are in some way controlled by the long-range very sparse connections (Kopell et al. 2000; von Stein et al. 2000; Buzsaki 2007; Lakatos et al. 2008; Uhlhaas et al. 2009).
In particular, future data might also help clarify whether the melodic information we observed in BOLD patterns of HG originated in HG was conveyed to it by sensory ascending activity, or whether it was fed back to HG from higher-level brain areas.
To determine the sensitivity of erythrocytes to SMase, erythrocytes were incubated with ascending activities of SMase and analyzed by flow cytometry.
Both connectives were cut at abdominal segment 1 in order to record only ascending neuronal activity encoding the activity of wind-sensitive inter-neurons.
The purpose of this work was to study the physiological influence of the endocannabinoid anandamide, the putative endogenous CB1 active cannabinoid, and of the CB1 receptor on ascending peristaltic activity and to identify the involved neuro-neuronal, neuro-muscular and electrophysiological mechanisms.
We use data from observations of the K-corona brightness, interplanetary scintillations (IPS) and photospheric magnetic fields during the descending (1983) and ascending solar activity phases (1976) to show that there exists a global structure in the output of solar plasma mass flux, Fm on the source surface (2.5RmRs→solar radius).
Both received input from ISNs, but ascending interneurons transmitted activity exclusively to excitatory motor neurons and descending interneurons transmitted activity exclusively to inhibitory motor neurons, forming two separate feedforward pathways.
We considered the unique role that lamina I serves as the source of ascending homeostatic afferent activity in the hierarchically organized sensori-motor network that drives efferent autonomic activity.
In the scheme presented, to reduce the interruptions to the primary and secondary users, we ordered the channels in the ascending order of activity.
Given these data, it seems more plausible that a lesion localized to the spinal cord has a greater propensity towards affecting ascending lamina I activity symmetrically on both sides if it disrupted descending modulation of ascending spinothalamic lamina I neurons bilaterally, resulting in dysfunctional "pain and temperature" sensibilities on both sides.
Both groups are thought to integrate primary afferent sensory signals with descending motor signals layers V and VII processing cutaneous and proprioceptive signals, respectively which Craig succinctly summarises as an ascending projection "conveying activity that represents the state of the segmental interneuronal pools that are used for motor control".
