Pioneer axon — is the part of an axon that lays down initial growing path for the other parts of the same axon to follow.ee also:*Axon guidance *Pioneer neuronReferences* [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve db=PubMed list uids=9344540… … Wikipedia
Axon guidance — (also called axon pathfinding) is a subfield of neural development concerning the process by which neurons send out axons to reach the correct targets. Axons often follow very precise paths in the nervous system, and how they manage to find their … Wikipedia
Pioneer neuron — is a cell that is a derivative of preplate in the early stages of corticogenesis of the brain. Pioneer neurons settle in the marginal zone of the cortex and project to sub cortical levels. In the rat, pioneer neurons are only present in prenatal… … Wikipedia

Synaptogenesis — is the formation of synapses. Although it occurs throughout a healthy person s lifespan, an explosion of synapse formation occurs during early brain development. Synaptogenesis is particularly important during an individual s critical period of… … Wikipedia
Netrin — 1 knockout disrupts thalamocortical projections topography. From Powell et al., 2008.[1] Netrins are a class of proteins involved in axon guidance. They are named after the Sanskrit word netr , which means one who guide … Wikipedia
Axoplasmic transport — Axoplasmic transport, also called axonal transport, is responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other cell parts to and from a neuron s cell body through the cytoplasm of its axon (the axoplasm). Axons,… … Wikipedia
Voltage clamp — The voltage clamp is used by electrophysiologists to measure the ion currents across a neuronal membrane while holding the membrane voltage at a set level. Neuronal membranes contain many different kinds of ion channels, some of which are voltage … Wikipedia
Unsolved problems in physics — This is a list of some of the major unsolved problems in physics. Some of these problems are theoretical, meaning that existing theories seem incapable of explaining some observed phenomenon or experimental result. The others are experimental,… … Wikipedia
Axoplasm — is the cytoplasm within the axon of a neuron. Neural processes (axons and dendrites) contain about 99.6% of the cell’s cytoplasm, and 99.7% of that is in the axons (Sabry et al., 1995). Axoplasm has a different composition of organelles and other … Wikipedia
