Neurogenesis cell migration differentiation synaptogenesis neuronal cell death synapse rearrangement
Which of the following summarizes what occurs during synapse rearrangement?
Neurons begin to develop specific shapes and functions.
Neurons scatter and begin to form into clumps of cells.
Some neural connections are eliminated, and new ones are formed.
Neurons in the brain create billions of connections, called synapses.

A child has an eight-ounce cup full of juice. While he watches, you pour the juice from the cup into a quart jar. He gets upset, because he thinks he now has less juice. The child is most likely in Piaget's _______ stage of cognitive development.
formal operational
sensorimotor
concrete operational
preoperational
Explanation / Answer
Answer 1.
The last option is the correct sequence.
Early embroyological events in the development of the different parts of the nervous system begins with formation of the nerve cells at birth, followed by transportation or migration of the neurons via the glial cells, then during the stage of cell differentiation neurons differentiate into specific neurons and glial cells and myelination occurs. After this, synapse develops between cells after birth and this stage is called synaptogenesis. During neuronal cell death in adolescence, cells undergo atrophy. Finally, as old and damaged neurons die, the functional and healthy cells realign their synapses and this process ends by the age of 25.
