Brain ! Why so beautiful.i)

P.S:This set of articles will be series of research perks on human brain and interesting catches !

Brain,the heart of life,that beats to the rhythm of numerous structures,pathways,connections and circuits.Its a part that is central organ of nervous system and holds the most essential functions to regulate us.Its a laboratory that is equipped with many parallel projects functioning together to maintain equilibrium.

Scientists have been constantly in to research exploring its vastness each day.Verily the creator,the lord of all has made this structure intricately beautiful ,one can appreciate it more once you begin to study its fineness.

I shall be highlighting a few of the research information that i have been following.

This article highlights on one of the most crucial debates in human paleoneurology which concerns the timing and mode of the emergence of the derived cerebral features in the hominin fossil record. Given its exceptional degree of preservation and geological age (i.e., 3.67 Ma), StW 573 (‘Little Foot’) has the potential to shed new light on hominin brain evolution.

In 1987, political scientist James Flynn of the University of Otago in New Zealand documented a curious phenomenon: broad intelligence gains in multiple human populations over time. 

 Researchers have also proposed a slew of other hypotheses to explain individual variation in human intelligence. The variety of proposed mechanisms underlines the scientific uncertainty about just how intelligence arises.Read article https://www.the-scientist.com/features/the-biological-roots-of-intelligence-64931?_ga=2.102641414.668049163.1546450789-1269576698.1546450789

The biological roots of Intelligence

 Below are three of these hypotheses, each backed by experimental evidence and computational modeling:

 Next is interesting to understand how brain brain cells filter information in groups?
A new study reports the neurons that focus on coarse visual details could change to prefer finer details under different conditions. The findings shed new light on the neural mechanism that helps shape our perception of the world.

When we perceive the world around us, certain objects appear to be more noticeable than others, depending on what we do. For example, when we view a forest-covered mountain from a distance, the forest looks like a large green carpet. But as we get closer, we start noticing the individual trees, and the forest fades to the background. What happens in the brain as our experience changes so drastically?
For decades, scientists studying the visual system thought that individual brain cells, called neurons, operate as filters. Some neurons would prefer coarse details of the visual scene and ignore fine details, while others would do the opposite. Every neuron was thought to do its own filtering.
A new study led by Salk Institute researchers challenges this view. The study revealed that the same neurons that prefer coarse details could change to prefer finer details under different conditions. The work, which appeared in the journal Neuron on December 31, 2018, could help to better understand neural mechanisms that shape our perceptions of the world.

There has been continuous research happening on the mechanism of brain functioning and each day some discovery is made.Thus further on i shall be reviewing and simplifying at-least five articles every week and putting it up on the blog for all the readers to gain benefit from the same.I anyone wishes to seek more information can write to me and i shall put up the required content.
