Document Summary
Attention: your brain is flooded with sensory information all the time but our brain ignores most of the signals. Attention to particular sensations permits filtering of less important sensations. Attention can be consciously directed, or guided by features inherent within sensory input. For example: our attention is unconsciously focused towards angry faces. 1994 - francis crick wrote the astonishing hypothesis where he stated that everything you experience as a human (feelings, sensations, etc) is a result of human brain activity. Dr. newsome studied monkeys, which have a very similar visual perception system to us. The monkeys were given a stimulus (100 dots moving) and they needed to tell the researcher what direction the dots were moving in. They moved their gaze/head in the direction the dots were moving in and were rewarded with drops of juice. Dr. newsome also placed electrodes onto a group of cells that had a specific function (example left motion)
