Smartphones have become basic, elemental and part of our lives. They are so useful for communication, have fun and of course, distinguish us among our friends according to the brand you have. On our day’s people are already addicted to this mobiles and even special boxes have been created to lock them away meanwhile you are in a meeting or some social event.
But the theme is not smartphones, but how someone has lived most of her young life without them. Ann Makosinski is a Canadian lady with 18 years old that got her first phone some months ago exactly because she would go to university and needed to call home.
Her incredible story starts on the way her parents grew her up and which is now helping her out to be a brilliant student. Watch her speech on a TED talk in the video below.
Lizzie Velasquez is a brilliant and fantastic 25-year-old lady who was born with a strange syndrome. In her special condition, she can not gain weight at all. During her life, many obstacles have overcome, but she has used them as a ladder to go after her dreams. As far as she´s gone she has achieved some of them and is after more.
Her speech is a motivation to all of those people that see life like a big mountain that they are not able to manage. Watch her incredible story and how she has turned negative into positive even though people attacked her for doing nothing them.
Attention isn’t just about what we focus on — it’s also about what our brains filter out. By investigating patterns in the brain as people try to focus, computational neuroscientist Mehdi Ordikhani-Seyedlar hopes to build computer models that can be used to treat ADHD and help those who have lost the ability to communicate.
“A new study by MIT neuroscientists reveals how the brain achieves this type of focused attention on faces or other objects: A part of the prefrontal cortex known as the inferior frontal junction (IFJ) controls visual processing areas that are tuned to recognize a specific category of objects, the researchers report in the April 10 online edition of Science.
Scientists know much less about this type of attention, known as object-based attention, than spatial attention, which involves focusing on what’s happening in a particular location. However, the new findings suggest that these two types of attention have similar mechanisms involving related brain regions, says Robert Desimone, the Doris and Don Berkey Professor of Neuroscience, director of MIT’s McGovern Institute for Brain Research, and senior author of the paper.
“The interactions are surprisingly similar to those seen in spatial attention,” Desimone says. “It seems like it’s a parallel process involving different areas.”
In both cases, the prefrontal cortex — the control center for most cognitive functions — appears to take charge of the brain’s attention and control relevant parts of the visual cortex, which receives sensory input. For spatial attention, that involves regions of the visual cortex that map to a particular area within the visual field.
In the new study, the researchers found that IFJ coordinates with a brain region that processes faces, known as the fusiform face area (FFA), and a region that interprets information about places, known as the parahippocampal place area (PPA). The FFA and PPA were first identified in the human cortex by Nancy Kanwisher, the Walter A. Rosenblith Professor of Cognitive Neuroscience at MIT. ” https://news.mit.edu/2014/how-brain-pays-attention
