The directed movement of cations, atoms or small molecules with a net positive charge, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Any process that modulates the frequency, rate or extent of synaptic activity, the controlled release of neurotransmitters into the synaptic cleft and their subsequent detection by a postsynaptic cell.

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

The process aimed at the progression of a neural crest cell over time, from initial commitment of the cell to its specific fate, to the fully functional differentiated cell.

The process in which the anatomical structures of the cranial skeleton are generated and organized during the embryonic phase.

The process whose specific outcome is the progression of the anterior lateral line over time, from its formation to the mature structure. The anterior lateral line consists of small sensory patches (neuromasts) located superficially on the skin or just under the skin in fluid-filled canals on the head of all fishes and most amphibians. The anterior lateral line develops from cranial ectodermal placodes situated between the eye and ear.

The process whose specific outcome is the progression of the posterior lateral line system over time, from its formation to the mature structure. The posterior lateral line system develops from cranial ectodermal placodes, situated behind the ear, that give rise to both the neuromasts and the posterior lateral line sensory nerves that innervate the neuromasts. The posterior lateral line system consists of small sensory patches (neuromasts) located superficially on the skin or just under the skin in fluid-filled canals on the head of all fishes and most amphibians. The neuromasts are innervated by several lateral line nerves, which project primarily to the hindbrain. The posterior mechanosensory lateral line system is stimulated by local water displacements and vibrations, and detects propulsion of the fish through the water, as well as facilitating shoaling, prey capture, and predator and obstacle avoidance.

A multimeric assembly of four or five subunits which form a structure with an extracellular N-terminus and a large loop that together form the ligand binding domain. The C-terminus is intracellular. The ionotropic glutamate receptor complex itself acts as a ligand-gated ion channel; on binding glutamate, charged ions pass through a channel in the center of the receptor complex.

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