Lesions can look like a variety of things. They can be light or dark spots, appear infected or reddish. If you think you may have a lesion it should be checked by a doctor.
Lesions done by knife cuts and suction techniques, called mechanical lesions, were tried by Veyssiere and Nothnagel in 1874. This process was done by inserting a fine wire blade through the head, rotating the curved or angled wire, and cutting neural projection. Baginski and Lehmann used this method with thin glass tube lowered through a small hole in the skull in 1886.
Lesions look NOTHING like.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
