The Neuronal cell cycle represents the life cycle of the biological cell, its creation, reproduction and eventual death. The process by which cells divide into two daughter cells is called mitosis . Once these cells are formed they enter G1, the phase in which many of the proteins needed to replicate DNA are made.
Dynamics of the theta model on the unit circle. Blue denotes a stable fixed point; Green denotes an unstable fixed point. By varying the input parameter, the two equilibria collide and form a stable limit cycle; Gray arrows indicate that the points are attracting in ; Black arrows indicate the direction of movement along the unit circle.
A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system. They are located in the brain and spinal cord and help to receive and conduct impulses.
The remainder of the ectoderm gives rise to the epidermis. The ability of the mesoderm to convert the overlying ectoderm into neural tissue is called neural induction. In the early embryo, the neural plate folds outwards to form the neural groove. Beginning in the future neck region, the neural folds of this groove close to create the neural tube.
The events of the synaptic vesicle cycle can be divided into a few key steps: [10] 1. Trafficking to the synapse. Synaptic vesicle components in the presynaptic neuron are initially trafficked to the synapse using members of the kinesin motor family. In C. elegans the major motor for synaptic vesicles is UNC-104. [11]
Recent follow-up of this work has shown that oscillations create periodic integration windows for Kenyon cells in the insect mushroom body, such that incoming spikes from the antennal lobe are more effective in activating Kenyon cells only at specific phases of the oscillatory cycle. [78] Neural oscillations are also thought be involved in the ...

The glutamate/GABA–glutamine cycle is a metabolic pathway that describes the release of either glutamate or GABA from neurons which is then taken up into astrocytes (non-neuronal glial cells). In return, astrocytes release glutamine to be taken up into neurons for use as a precursor to the synthesis of either glutamate or GABA. [2]
