Even with massive amounts of information drowning our senses, we can focus on what is important and take action.
The brain’s ability to focus on a particular signal while filtering out the rest is now being studied by neuroscientists in detail, and the decades-old studies of the brain cortex being responsible for the same are now proving to be incomplete.
The brain’s ability to focus on one thing while obscuring, curbing or reducing the signal strength of other (presumably unwanted) stimuli can be dangerous if those turn out to be unexpectedly important.
The brain, evolved as it is, has a unique way to handle this issue, by reducing the signal strength of the focused object about four times per second, suppressing what’s important to focus on the other signals, some of which may also be important. The brain is already wired to blink.
Neuroscientists are now also looking at the basal ganglia region of the brain, commonly associated with motor control, apart from reward-based learning and decision making.
The new frontiers of this study include the brain’s attention, action cues and even the elusive subject of consciousness.
The brain, it seems, is interlinked and interconnected in many ways yet to be understood.
