    GO:0045161    neuronal ion channel clustering    The process in which voltage-gated ion channels become localized to distinct subcellular domains in the neuron.

Long-term neuronal synaptic plasticity generally involves increase or decrease in actual synapse numbers.
    GO:0035176    social behavior    Behavior directed towards society, or taking place between members of the same species. Occurs predominantly, or only, in individuals that are part of a group.
    GO:0016188    synaptic vesicle maturation    Steps required to form an initiated synaptic vesicle into a fully formed and transmissible synaptic vesicle.
    GO:0071625    vocalization behavior    The behavior in which an organism produces sounds by a mechanism involving its respiratory system.
cellular component
    GO:0032281    AMPA glutamate receptor complex    An 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 AMPA receptors mediate fast synaptic transmission in the CNS and are composed of subunits GluR1-4, products from separate genes. These subunits have an extracellular N-terminus and an intracellular C-terminus.
    GO:0030424    axon    The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
    GO:0016323    basolateral plasma membrane    The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.
    GO:0030054    cell junction    A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix.
    GO:0042995    cell projection    A prolongation or process extending from a cell, e.g. a flagellum or axon.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0032839    dendrite cytoplasm    All of the contents of a dendrite, excluding the surrounding plasma membrane.
    GO:0043197    dendritic spine    A small, membranous protrusion from a dendrite that forms a postsynaptic compartment - typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable including "thin", "stubby", "mushroom", and "branched", with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.
    GO:0005783    endoplasmic reticulum    The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
    GO:0060076    excitatory synapse    A synapse in which an action potential in the presynaptic cell increases the probability of an action potential occurring in the postsynaptic cell.
    GO:0031234    extrinsic component of cytoplasmic side of plasma membrane    The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region.
    GO:0008328    ionotropic glutamate receptor complex    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.
    GO:0044224    juxtaparanode region of axon    A region of an axon near a node of Ranvier that is between the paranode and internode regions.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0044306    neuron projection terminus    The specialized, terminal region of a neuron projection such as an axon or a dendrite.
    GO:0044309    neuron spine    A small membranous protrusion, often ending in a bulbous head and attached to the neuron by a narrow stalk or neck.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0014069    postsynaptic density of dendrite    An electron dense network of proteins within and adjacent to the postsynaptic membrane of the dendrite of 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.
    GO:0045211    postsynaptic membrane    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.
    GO:0045202    synapse    The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
    GO:0008021    synaptic vesicle    A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.
    GO:0008076    voltage-gated potassium channel complex    A protein complex that forms a transmembrane channel through which potassium ions may cross a cell membrane in response to changes in membrane potential.
