biological process
    GO:0007628    adult walking behavior    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.
    GO:0006915    apoptotic process    A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
    GO:0008088    axo-dendritic transport    The directed movement of organelles or molecules along microtubules in neuron projections.
    GO:0048675    axon extension    Long distance growth of a single axon process involved in cellular development.
    GO:0007409    axonogenesis    De novo generation of a long process of a neuron, that carries efferent (outgoing) action potentials from the cell body towards target cells. Refers to the morphogenesis or creation of shape or form of the developing axon.
    GO:0007420    brain development    The process whose specific outcome is the progression of the brain over time, from its formation to the mature structure. Brain development begins with patterning events in the neural tube and ends with the mature structure that is the center of thought and emotion. The brain is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).
    GO:0007565    female pregnancy    The set of physiological processes that allow an embryo or foetus to develop within the body of a female animal. It covers the time from fertilization of a female ovum by a male spermatozoon until birth.

    GO:0008631    intrinsic apoptotic signaling pathway in response to oxidative stress    A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced in response to oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, and ends when the execution phase of apoptosis is triggered.
    GO:0000226    microtubule cytoskeleton organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising microtubules and their associated proteins.

    GO:0032387    negative regulation of intracellular transport    Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of substances within cells.
    GO:0001764    neuron migration    The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature.

    GO:0031116    positive regulation of microtubule polymerization    Any process that activates or increases the frequency, rate or extent of microtubule polymerization.
    GO:0010506    regulation of autophagy    Any process that modulates the frequency, rate or extent of autophagy. Autophagy is the process in which cells digest parts of their own cytoplasm.
    GO:0031113    regulation of microtubule polymerization    Any process that modulates the frequency, rate or extent of microtubule polymerization.
    GO:0060632    regulation of microtubule-based movement    Any process that modulates the rate, frequency, or extent of microtubule-based movement, the movement of organelles, other microtubules and other particles along microtubules, mediated by motor proteins.
    GO:0007584    response to nutrient    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nutrient stimulus.
    GO:0010033    response to organic substance    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an organic substance stimulus.
cellular component
    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:0005930    axoneme    The bundle of microtubules and associated proteins that forms the core of cilia (also called flagella) in eukaryotic cells and is responsible for their movements.
    GO:0044297    cell body    The portion of a cell bearing surface projections such as axons, dendrites, cilia, or flagella that includes the nucleus, but excludes all cell projections.
    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:0036464    cytoplasmic ribonucleoprotein granule    A ribonucleoprotein granule located in the cytoplasm.
    GO:0005856    cytoskeleton    Any of the various filamentous elements that form the internal framework of cells, and typically remain after treatment of the cells with mild detergent to remove membrane constituents and soluble components of the cytoplasm. The term embraces intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0030425    dendrite    A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
    GO:0030426    growth cone    The migrating motile tip of a growing nerve cell axon or dendrite.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

    GO:0097418    neurofibrillary tangle    Intracellular mass of paired, helically wound protein filaments (also called PHF) lying in the cytoplasm of neuronal cell bodies and neuritic cell processes. Neurofibrillary tangles contain an abnormally phosphorylated form of a microtubule-associated protein, tau. The shape of these inclusions may resemble a flame or a star.
    GO:0043005    neuron projection    A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
    GO:0034399    nuclear periphery    The portion of the nuclear lumen proximal to the inner nuclear membrane.
    GO:0005634    nucleus    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.
    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.
