The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. Brain development begins with patterning events in the neural tube and ends with the mature structure that is the center of thought and emotion.

Any process that modulates the rate or extent of progression through the meiotic cell cycle.

Any process in which is the spindle is transported to, and/or maintained in, a specific location.

Any process in which is the spindle is transported to, and/or maintained in, a specific location.

Any process in which a centrosome is maintained in a specific location within a cell and prevented from moving elsewhere.

Any process that increases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes.

The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of meiosis.

Any process in by an organism or tissue maintains a population of neuronal stem cells.

Either of the ends of a spindle, where spindle microtubules are organized; usually contains a microtubule organizing center and accessory molecules, spindle microtubules and astral microtubules.

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.

In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing.
