The Split Brain

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The study of how damage to the brain affects cognitive functioning has historically been one of the most important tools for cognitive neuroscience. While the brain is one of the most well protected parts of the body, there are many events that can affect the functioning of the brain. Vascular issues, tumors, degenerative diseases, infections, blunt force traumas, and neurosurgery are just some of the...

Stock Split

2025
A stock split is a corporate action aimed at increasing the number of a company's shares by dividing its existing shares into multiple new ones. This adjustment reduces the per-share price without altering the company's overall market capitalization, thereby making shares more affordable to investors and enhancing trading flexibility. Stock splits are often employed by companies whose stock prices have risen significantly, making their shares less accessible to retail investors. Lowering the...

This video demonstrates how to maintain the growth of human embryonic stem cells (hESCs) in feeder cell-free conditions and how to continuously passage hESCs in feeder cell-free conditions. Confirmation of hESC pluripotency grown in feeder cell-free conditions by immunofluorescence microscopy is also demonstrated. Part 2 of 3.

¹H NMR: Complex Splitting
0 Views •
2024
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet. Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.

Using a Split-belt Treadmill to Evaluate Generalization of Human Locomotor Adaptation

We describe a protocol for investigating human locomotor adaptation using the split-belt treadmill, which has two belts that can drive each leg at a different speed. We specifically focus on a paradigm designed to test the generalization of adapted locomotor patterns to different walking contexts (e.g., gait speeds, walking environments).

The oxygen-evolving complex is the reaction center within Photosystem II where light-driven water oxidation occurs. It releases oxygen, protons, and electrons in a coordinated process rather than producing only one useful product. This makes the complex central to linking photon capture with both electron transfer and proton-gradient formation in oxygenic photosynthesis.
The released electrons help sustain the energy-transfer reactions initiated by Photosystem II, while the protons contribute to a gradient across a membrane. That gradient supports ATP production, and the overall flow of energy and reducing power helps support carbon fixation. Water splitting therefore connects the initial light reaction with chemical-energy storage.
Light supplies the energy needed to drive the oxidation of water at Photosystem II. Without this energy input, the reaction would not provide the electrons and protons required for downstream photosynthetic processes. This dependence explains how plants, algae, and cyanobacteria couple sunlight capture to oxygen release and energy conversion.
A useful analysis follows the reaction from its immediate products to its larger photosynthetic consequences. Researchers can consider oxygen release, electron availability, proton-gradient formation, ATP production, and support for carbon fixation as connected outcomes. Examining these links helps clarify how plants, algae, and cyanobacteria convert light energy into chemical energy.
The reaction provides a biological model for artificial photosynthesis, bio-inspired catalysts, and renewable hydrogen production. Natural systems show how light can drive the conversion of water while generating chemically useful products. Studying their principles can therefore guide technologies that seek to reproduce or adapt energy-transfer strategies found in photosynthetic organisms.
Oxygen release from oxygenic photosynthesis connects this reaction to the development of oxygen-rich environments. Its study therefore extends beyond cellular energy conversion into questions about how organisms altered their surroundings over time. Comparing plants, algae, and cyanobacteria also helps place photosynthetic water oxidation within the broader biological context of oxygen production.
