Animals learned to move their eyeballs once every second, a completely internal timing feat made possible by
the rhythmic behavior of small groups of nerve cells, researchers propose online October 30 in PLOS Biology.
Amita Sehgal, PhD, a professor of Neuroscience at the Perelman School of Medicine, University of Pennsylvania, describes in Cell a circuit in the brain of fruit flies that controls their daily,

Indeed, chimpanzees and bonobos display bouts
of rhythmic drumming as part
of display or play
behavior.
Rhythmic behavior has recently been observed in other animals, including parrots, budgerigars, sea lions, rhesus monkeys, and chimpanzees, although in the majority
of these cases animals were explicitly trained to synchronize.
They found that cells in the pars intercerebralis (PI) are essential for
rhythmic behavior, and PI cells are connected to the clock cells through a circuit
of at least two synapses.
miR - 124 regulates diverse aspects
of rhythmic behavior in Drosophila.
For example, our studies identified transcription factors, RNA binding proteins, and signaling genes as critical miRNA targets during contexts such as development
of peripheral sensory organs, wing, eye, and CNS, or during behavioral contexts such as egg - laying,
rhythmic behavior, and locomotor activity (Figure 2).
Interactional synchrony is form
of rhythmic interaction between infant and caregiver involving mutual focus, reciprocity and mirroring
