The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The behavior of an adult relating to the progression of that organism along the ground by the process of lifting and setting down each leg.

The recognition of molecules at a choice point by an axon growth cone; at a choice point the growth cone determines the direction of its future growth.

The process that gives rise to a rhombomere boundary. This process pertains to the initial formation of a boundary delimiting a rhombomere. Rhombomeres are transverse segments of the developing rhombencephalon that are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order.

The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the T cell receptor to augment T cell activation.

The series of molecular signals generated as a consequence of an ephrin receptor binding to an ephrin.

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

Cell-cell signaling between presynapse and postsynapse, mediated by transynaptic protein complexes, that modulates the synaptic transmission properties of the synapse.

Cell-cell signaling between presynapse and postsynapse, mediated by transynaptic protein complexes, that modulates the synaptic transmission properties of the synapse.

The series of molecular signals generated as a consequence of an ephrin receptor binding to an ephrin.

Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.

The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.

The series of molecular signals generated as a consequence of an ephrin receptor binding to an ephrin.

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

A synapse that uses glutamate as a neurotransmitter.

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

One of the giant synapses that form between the mossy fiber axons of dentate gyrus granule cells and the large complex spines of CA3 pyramidal cells. It consists of a giant bouton known as the mossy fiber expansion, synapsed to the complex, multiheaded spine (thorny excresence) of a CA3 pyramidal cell.
