Daily learning keeps brain healthy


edf40wrjww2articles:details

Everyday forms of learning help keep brain cells functioning at optimum levels thus also limiting the effects of age-related cognitive and memory decline, a recent study has found.

Using a novel visualization technique a research team led by Lulu Chen and Christine Gall found that everyday forms of learning animate neuron receptors which facilitates the growth and differentiation of the connections, or synapses, responsible for communication among neurons. BDNF is key in the formation of memories.

"The findings confirm a critical relationship between learning and brain growth and point to ways we can amplify that relationship through possible future treatments," says Chen, a graduate researcher in anatomy & neurobiology.

Study results appear in the early online edition of the Proceedings of the National Academy of Sciences

In addition to discovering that brain activity sets off BDNF signaling at the sites where neurons develop synapses, researchers determined that this process is linked to learning-related brain rhythms, called theta rhythms, vital to the encoding of new memories.

Theta rhythms occurring in the hippocampus involve numerous neurons firing synchronously at a rate of three to eight times per second. These rhythms have been associated with long-term potentiation, a cellular mechanism underlying learning and memory.

In rodent studies, the team found that both unsupervised learning and artificial application of theta rhythms triggered BDNF signaling at synapse creation sites.

Researchers are now exploring whether learning-induced growth signals decrease with age and, if so, whether this can be reversed with a new family of experimental drugs.

Corruption Watch

The bad news is that corruption has not only sustained but has grown in size and stature in the country. With scams being a regular feature, seventy per cent respondents in a survey have rightfully opined that corruption has continued to increase in India. One in every two interviewed admit having paid a bribe for availing public services during last one year. Transparency International's latest survey reveals that the political parties top the chart for the most corrupt public institutions, followed by police force and legislatures. No wonder, India continues to make new records on the global corruption arena!

The shocking revelation is that the health and education sectors haven't remained untouched by this phenomenon. With 5th and 6th positions respectively for these sectors on the public perception chart on corruption, corruption has crept insidiously into these sectors of hope for the masses. With bureaucracy being fourth in the list of corrupt institutions in the country, corruption seems to have been non-formally institutionalized with little hope if public services would ever be effective in the country. With economic growth having literally institutionalized corruption, are we now expecting corrupt to be socially responsible - a different CSR.

Poor. Who?

Not giving 'aid' to India is one thing but calling it 'rich' is quite another. If one in three of the world's malnourished children live in India, what does average daily income of $3 indicate? It perhaps means that there is a relative decline in poverty - people are 'less poor' than what they used to be in the past. But having crossed the World Bank arbitrary threshold of $2 a day does not absolve the 'developed' countries of their obligation to part with 0.7 per cent of their Gross National Income in development aid. Should this three-decade old figure not be revised?  

An interesting debate in UK's House of Commons delved on future of development assistance by the British Government. While prioritizing limited resources has been a concern, there has been no denying the fact that development aid must be guided towards tangible gains over a short period of time to start with. There are difficult choices for elected governments to make - should they invest in long-term primary education or in short-term university scholarships? Which of these will bring gains and trigger long-term transformation in the society. As politicians continue to be divided on the matter, poverty persists!!
