A team of researchers has uncovered new clues about how chemicals released by brain cells regulate our attention span.
A team of researchers from Nanyang Technological University, Singapore has uncovered new clues about how chemicals released by brain cells regulate our attention span.
These chemicals also coordinate cognitive processes that enable us to focus on important information within the constant barrage of stimuli the brain receives from the external environment, otherwise known as our attention span. . Optogenetics uses light-sensitive proteins to selectively control the activity of specific types of neurons within the brain. In this case, the neurons within the forebrain that release acetylcholine and GABA were activated by light, allowing the team to measure the response of the claustrum to such a stimulus.
The opposing actions of the neurotransmitters on neurons in the claustrum enable brain signals to be encoded efficiently, allowing the brain to pay attention and ignore noise.First author Mr Aditya Nair, former researcher at LKCMedicine and a current Ph.D. student at Caltech, said,"Our study advances our understanding of the claustrum's role in directing attention span.

We could sequester CO2 by 're-greening' arid lands, plant scientists sayReducing CO2 levels in the atmosphere will take more than cutting emissions—we will also need to capture and store the excessive volumes of already-emitted carbon. In an opinion paper published in the journal Trends in Plant Science on September 21, a team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.
