Notch Signaling in Central Nervous System Development and Function
Early findings on Notch signaling in Central Nervous System (CNS) development were mainly performed in Drosophila with mutagenesis experiments. For example, the finding that an embryonic lethal phenotype in Drosophila was associated with Notch dysfunction indicated that Notch mutations can lead to the failure of neural and Epidermal cell segregation in early Drosophila embryos. In the past decade, advances in mutation and knockout techniques allowed research on the Notch signaling pathway in mammalian models, especially rodents.
The Notch signaling pathway was mainly found to be critical for neural progenitor cell (NPC) maintenance and self-renewal. In recent years, other functions of the Notch pathway have also been found, including glial cell specification, neurites development as well as learning and memory.

Famous quotes containing the words notch, central, nervous, system, development and/or function:
“Father Time is not always a hard parent, and, though he tarries for none of his children, often lays his hand lightly upon those who have used him well; making them old men and women inexorably enough, but leaving their hearts and spirits young and in full vigour. With such people the grey head is but the impression of the old fellow’s hand in giving them his blessing, and every wrinkle but a notch in the quiet calendar of a well- spent life.”
—Charles Dickens (1812–1870)
“My solitaria
Are the meditations of a central mind.
I hear the motions of the spirit and the sound
Of what is secret becomes, for me, a voice
That is my own voice speaking in my ear.”
—Wallace Stevens (1879–1955)
“Toward education marriage nervous breakdown, operation, teaching
school, and learning to be mad, in a dream—what is this
life?”
—Allen Ginsberg (b. 1926)
“Each generation’s job is to question what parents accept on faith, to explore possibilities, and adapt the last generation’s system of values for a new age.”
—Frank Pittman (20th century)
“The American has dwindled into an Odd Fellow—one who may be known by the development of his organ of gregariousness.”
—Henry David Thoreau (1817–1862)
“Think of the tools in a tool-box: there is a hammer, pliers, a saw, a screwdriver, a rule, a glue-pot, nails and screws.—The function of words are as diverse as the functions of these objects.”
—Ludwig Wittgenstein (1889–1951)
