Investigating the Relationship Between Circadian Rhythm and Learning-Memory

open access: yesTürk Uyku Tıbbı Dergisi
The circadian rhythm creates many metabolic changes in our body by influencing the activities of suprachiasmatic nucleus and other centers in the cerebrum according to the light-dark conditions within a 24-hour period.

Circadian rhythm of leaf movement in Capsicum annuum observed during centrifugation [PDF]

open access: yes
Plant circadian rhythms of leaf movement in seedlings of the pepper plant (Capsicum annuum L., var. Yolo Wonder) were observed at different g-levels by means of a centrifuge.

Diagrams as Vehicles for Scientific Reasoning [PDF]

open access: yes, 2013
We argue that diagrams are not just a communicative tool but play important roles in the reasoning of biologists: in characterizing the phenomenon to be explained, identifying explanatory relations, and developing an account of the responsible mechanism.

EVOLUTION OF THE CIRCADIAN CLOCK IN EXTREME ENVIRONMENT: LESSONS FROM CAVEFISH. [PDF]

open access: yes, 2010
Evolution has been strongly influenced by the daily cycles of temperature and light imposed by the rotation of the Earth. Fascinating demonstrations of this are seen in extreme environments such as caves where some animals have remained completely ...

open access: yes, 2008
Circadian rhythm is a bological clock that regulate physiological function and human behaviour. Melatonin is an agent which is effected and regulated by circadian rhythm through photoreceptor activity.

Notes on Circadian Rhythm

open access: yes, 2013
We discuss a class of models arising in the study of circadian rhythm and the properties of the matrix equations providing the bifurca- tion points for a wide parameter class. In particular, we prove that the five dimensional system studied in the cited work of Gonze, Halloy, and Goldbeter can have only a simple Hopf bifurcation.

The CoREST complex regulates multiple histone modifications temporal-specifically in clock neurons

open access: yesOpen Biology
Epigenetic regulation is important for circadian rhythm. In previous studies, multiple histone modifications were found at the Period (Per) locus. However, most of these studies were not conducted in clock neurons.
