WebDiatoms are an extraordinarily diverse, evolutionarily successful, and ecologically important group of single-cell algae. Diatoms of the group of the … WebExperiments in rats have shown that two subgroups of oscillators within the SCN, a ventrolateral (VL) subgroup that receives photic input and a dorsomedial (DM) subgroup that is coupled to VL, can be desynchronized under a short (22-h) T cycle, with VL entrained to the cycle and DM free-running.

WebThe photic driving response and the photic hypersensitivity are similar as both are induced by light stimulation. The photic driving response in a high-stimulation region of 15 Hz or more (an H-response) is thought to be abnormal, and migraine patients frequently show the H-response during the interictal phase [4]. WebPhotocycle definition: (biochemistry, physics) Any of several biochemical cycles , involving photoactive proteins , that take place in the retina when exposed to light. .

Cyclic Photophosphorylation happens with the help of photosynthesis, a process of producing carbohydrates by green plants using carbon … WebInsects express diverse behavioral rhythms synchronized to environmental cycles. While circadian entrainment to light–dark cycles is ubiquitous in living organisms, synchronization to non-photic cycles may be critical for hematophagous …
WebFeb 4, 2005 · The data show that PZE conditions occurred during the P-T superanoxic event and document a major disruption of the carbon and sulfur cycles. The onset of PZE in Hovea-3 coincides with a sharp facies change, reflecting rapid transgression (e.g., 23 ). The association of oxygen-poor water and rapid transgression is key for the hypothesis that ...
