What is the name of the single cell that results from the union of the parents sex cells at fertilization?
Human fertilization fertilization process. Human fertilization Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development. Scientists discovered the dynamics of human fertilization in the nineteenth century. The process of fertilization involves a sperm fusing with an ovum. The most common sequence begins with ejaculation during copulation, follows with ovulation, and finishes with fertilization. Various exceptions to this sequence are possible, including artificial insemination, "in vitro" fertilization, external ejaculation without copulation, or copulation shortly
Alternative explanations of the "grandmother" cell contexts. The distributive explanation argues that the grandmother cell is nothing but the single-neuron output stage of a neural network trained to recognize a person. The hypothetical grandmother cell does not have any extraordinary binding properties. They are properties of the neural network instead. Although Kreiman's and Quiroga's results may seem to challenge the distributive model of the brain, the distributive theory offers a simple explanation of these phenomena. Such cells serve as the output neurons for neural networks trained to recognize the famous persons in question.
