Americans Rate Losing Eyesight As Having Greatest Impact On Their Lives
Many Americans across racial and ethnic groups describe losing eyesight as potentially having the greatest impact on their day-to-day life, more so than other conditions including: loss of limb, memory, hearing and speech, a survey shows.
New insight into eye diseases
Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, known as Muller glial cells (MGs), do serve as retinal stem cells that are capable of generating new cells. In a new study, a research team investigated whether the regenerative power of cells in zebrafish could be recreated in mammals, specifically mice. Ref. Source 5g.
Brain 'rewires' itself to enhance other senses in blind people
The brains of those who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions (Such as memory and language) according to a new study. Ref.
Well people who are blind can do things seeing people can not. Can you tell a $ from a $20 or a $1? They can I know I can not. That shows that yes their brain heightens their other senses and memory among other things.
The brain is an amazing an amazing organ and has many ways of adjusting to cope for the loss of a sense. With the loss of sight, hearing and often touch improve. The blind that I know cannot tell a $1 bill from a $20, but they can tell the various coins from one another. Likewise, many are able to adapt to using a cane or service animal rather quickly.
