Ray Rappaport (May 1922 – December 14, 2010) was an American cell biologist.
He did pioneering research using physical manipulations of cells to understand the mechanisms of cytokinesis.
Cytokinesis: The process by which a cell's cytoplasm is divided in two.
Cell
Cell Cycle
Cytokinesis in Animal cells
Cytokinesis
The parent cells splits into two daughter cells
Cell Division
The Neuron
Neurons: Oldest and longest cells in the human body
Neurons cannot divide via mitosis
Human: 16.3 Billion Neurons
Human: Brain To Body Weight 2.1%
2 % of Body weight requires 20 % of the bodys energy
10 % of the brain is only used
Albert Einstein
Dr Thomas Harvey performed the autopsy on Einsteins Brain
Einsteins Brain: Neuroglia outnumber neurons in 10 to 1
Neuroglia
Schwann Cells/Oligodendrocytes: Myelin Production
Myelin: Speed of transmission of electrical impulses
Einsteins brain did not have larger or more than normal amount of neurons
Einsteins brain had more glial cells indicating more metabolic need
Size and weight of your brain makes no difference to how smart you are
Weight lifting makes no change in the weight of your brain
The Biology Of A Genius
Albert Einstein
Everybody is a Genius
Human Biology Is Limitless
