William Ayliffe: Why We See What We Do

William Ayliffe (Gresh College)Via Gresham College/Fora.tv:

The visual system has developed to allow us to navigate in a complex and dangerous world in order to find food and to avoid danger.

This survival system works by building a complex three-dimensional model based on two-dimensional data from the retina.

This model is tested against “reality” and checked with information from other senses and updated if needed. The brain suppresses the complexity of this processing and we believe that vision is instantaneous, real and effortless.

But is seeing just an illusion?Watch Full Movie Online Streaming Online and Download?

Musical Minds

Oliver Sacks (Wikipedia)Can the power of music make the brain come alive? Watch Passengers (2016)

Throughout his career Dr. Oliver Sacks, neurologist and acclaimed author, whose book Awakenings was made into a Oscar-nominated feature film starring Robin Williams and Robert De Niro, has encountered myriad patients who are struggling to cope with debilitating medical conditions.watch Vacation 2015 movie online now

While their ailments vary, many have one thing in common: an appreciation for the therapeutic effects of music.

NOVA follows four individuals — two of whom are Sacks’s case studies — and even peers into Sacks’s own brain, to investigate music’s strange, surprising, and still unexplained power over the human mind.

BBC: The Story of Science – Who Are We?

Who Are We? is the title of the final episode from the BBC series The Story of Science: Power, Proof and Passion.

Michael Mosley

Michael Mosley takes an informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society’s historical path.

We now know that the brain – the organ that more than any other makes us human – is one of the wonders of the universe, and yet until the 17th century it was barely studied.

The twin sciences of brain anatomy and psychology have offered different visions of who we are. Now these sciences are coming together and in the process have revealed some surprising and uncomfortable truths about what really shapes our thoughts, feelings and desires.

And the search to understand how our brains work has also revealed that we are all – whether we realise it or not – carrying out science from the moment we are born.
