Rhythmicity is a word that describes the quality of being rhythmic or having a regular pattern. It refers to something that is organized and repeated in a predictable way, like the beat of a drum or the waves of the ocean.
Full definition
Human EEG recordings show clear theta
rhythmicity in some situations, but because of the technical difficulties, it has been difficult to tell whether these signals have any relationship with the hippocampal theta signals recorded from other species.
The generation of the rhythm is dependent on the medial septal area: this area projects to all of the regions that show
theta rhythmicity, and destruction of it eliminates theta throughout the brain (Stewart & Fox, 1990).
To
determine rhythmicity, the researchers looked at the activity patterns of zebrafish larvae in 48 - well plates in DanioVision.
Green and Arduini described an inverse relationship between hippocampal and cortical activity patterns, with
hippocampal rhythmicity occurring alongside desynchronized activity in the cortex, whereas an irregular hippocampal activity pattern was correlated with the appearance of large slow waves in the cortical EEG.
In rats, the most frequently studied species, theta
wave rhythmicity is easily observed in the hippocampus, but can also be detected in numerous other cortical and subcortical brain structures.
Apples, such as forepart massagers or canes intentional to help you writer
contest rhythmicity!
While past exhibitions have been limited to a single repeated subject, the artist's driving concern with seriality manifests here as a network of motifs and themes, endowing the exhibition with a
discernable rhythmicity.
General activity level and
sleep rhythmicity did not moderate the effect of peer behavior on delinquency.
For example, Sima Smadja Storz and her colleagues at this lab investigated the role of casein kinase 1 (CK1), which are enzymes that function as regulators of
circadian rhythmicity (research published in PLoS ONE, 2013).

«Since urine formation and excretion by the kidney is one of the most easily detectable rhythmic processes (we are forming and excreting much more urine during the day), we hypothesized that at least a part of
this rhythmicity is dependent on the circadian clock mechanism,» said Dr. Tokonami.
Indeed, these latter animals completely lost
their rhythmicity after 2 weeks in the dark, implying that a part in their internal clocks was broken.
The training that his dissertation examines differs from the traditional sport - specific exercises that athletes normally perform: over four weeks golfers and soccer players spent time training up their timing and
rhythmicity, where various non-sport specific rhythmic movements were performed in time to a digital metronome.
Practicing your timing and
rhythmicity can make you a more precise and stable golfer or soccer player.
«This research adds to the accumulating evidence that «time of day» or «circadian
rhythmicity» matters in medicine,» says Derk - Jan Dijk, of the University of Surrey, UK.
We measured gene expression of Cry1, Cry2 and Cry4 in the retina, muscle and brain of zebra finches over the circadian day to assess whether they showed any circadian
rhythmicity.
«This [concept] has been previously described in other biological processes, such as circadian
rhythmicity, the cell cycle, and even stem cell pluripotency, but is shown here through a systematic analysis of a data - driven computational model.»
Zebrafish larvae normally develop circadian
rhythmicity when exposed to light / dark cycles, after which the animals are able to maintain this rhythmicity even under continuous light conditions.
DanioVision is a complete system designed for exactly these types of experiments with zebrafish larvae, and is often used in studies related to drug development, safety pharmacology, behavioral genetics, and circadian
rhythmicity.
However, the fish pineal gland seems to have all the elements for the generation of circadian
rhythmicity.
They can reveal information on stereotypic and epileptic behaviors, circadian
rhythmicity, motor control, movement disorders, neural development, and more.
Read about more studies on circadian
rhythmicity in zebrafish in this other case about casein kinase and rhythmicity.
It is for anybody performing research in drug development, safety pharmacology, behavioral genetics, circadian
rhythmicity and related research areas.
In larvae that were exposed to the CK1δ inhibition,
rhythmicity was completely diminished.
Way back in 1998 when I was graduating high school, Murphy and colleagues were screwing with «light - entrainable» and «food - entrainable» oscillators of circadian
rhythmicity (1998).
She reported no significant group differences for any of the following: activity,
rhythmicity, approach, adaptability, mood, persistence, distractibility, intensity or threshold.
