Any process that modulates the frequency, rate or extent of small GTPase mediated signal transduction.

The rearrangements of the microtubule cytoskeleton that result in the extension of a leading process, where this process is involved in the movement of cells along radial glial cells.

Any process that activates or increases the activity of a GTPase.

The assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.

The process in which the anatomical structures of a neuron projection are generated and organized. A neuron projection is any process extending from a neural cell, such as axons or dendrites.

The process in which an actin filament is broken down into smaller filaments.

Any process that stops, prevents or reduces the frequency, rate or extent of neuron migration.

Formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell that contributes to the directed self propelled movement of a cell.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

An electron dense network of proteins within and adjacent to the postsynaptic membrane in asymetric synapses. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components.

Distal part of the dendritic spine, that carries the post-synaptic density.

A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane.

A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. 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. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

That part of the nuclear content other than the chromosomes or the nucleolus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.
