32 GO annotations of biological process
Name | Definition |
---|---|
axon extension involved in regeneration | Long distance growth of a single axon process involved in regeneration of the neuron. |
cellular response to nerve growth factor stimulus | A process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a nerve growth factor stimulus. |
cellular response to retinoic acid | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a retinoic acid stimulus. |
circadian rhythm | Any biological process in an organism that recurs with a regularity of approximately 24 hours. |
cochlea development | The progression of the cochlea over time from its formation to the mature structure. The cochlea is the snail-shaped portion of the inner ear that is responsible for the detection of sound. |
heart development | The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood. |
lens fiber cell differentiation | The process in which a relatively unspecialized cell acquires specialized features of a lens fiber cell, any of the elongated, tightly packed cells that make up the bulk of the mature lens in the camera-type eye. The cytoplasm of a lens fiber cell is devoid of most intracellular organelles including the cell nucleus, and contains primarily crystallins, a group of water-soluble proteins expressed in vary large quantities. |
mechanoreceptor differentiation | The process in which a relatively unspecialized cell acquires specialized features of a mechanoreceptor, a cell specialized to transduce mechanical stimuli and relay that information centrally in the nervous system. |
myelination in peripheral nervous system | The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of Schwann cells in the peripheral nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier. |
negative regulation of astrocyte differentiation | Any process that stops, prevents, or reduces the frequency, rate or extent of astrocyte differentiation. |
negative regulation of protein phosphorylation | Any process that stops, prevents or reduces the rate of addition of phosphate groups to amino acids within a protein. |

neuron migration | The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature. |
neuronal action potential propagation | The propagation of an action potential along an axon, away from the soma. |
phosphorylation | The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. |

positive regulation of neuron projection development | Any process that increases the rate, frequency or extent of neuron projection development. Neuron projection development is the process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites). |

response to corticosterone | 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 corticosterone stimulus. Corticosterone is a 21 carbon steroid hormone of the corticosteroid type, produced in the cortex of the adrenal glands. In many species, corticosterone is the principal glucocorticoid, involved in regulation of fuel metabolism, immune reactions, and stress responses. |
