Deep lesioning

Insertion of a thin insulated wire into the brain through which an electrical current is sent that destroys the brain cells at the tip of the wire is called deep lesioning.

Deep lesioning is a surgical procedure in which a small specific area of the brain is destroyed in order to provide treatment for certain disorders. Deep lesioning are used in the treatment of movement disorders such as Parkinson’s disease, dystonia and essential tremor. Several methods such as radiofrequency lesion, radiosurgery and focused ultrasound therapy are  used to cause deep lesion.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.
