The initiation of the activity of the inactive enzyme MAP kinase (MAPK).

An acute behavioral change resulting from a perceived external threat.

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 amphetamine stimulus. Amphetamines consist of a group of compounds related to alpha-methylphenethylamine.

Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell.

A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).

The series of molecular signals generated as a consequence of a dopamine receptor binding to its physiological ligand, where the pathway proceeds with inhibition of adenylyl cyclase and a subsequent decrease in the concentration of cyclic AMP (cAMP).

The series of molecular signals generated as a consequence of a dopamine receptor binding to its physiological ligand, where the pathway proceeds with inhibition of adenylyl cyclase and a subsequent decrease in the concentration of cyclic AMP (cAMP).

The series of molecular signals generated as a consequence of a dopamine receptor binding to one of its physiological ligands.

Locomotory behavior in a fully developed and mature organism.

Any process that activates or increases the activity of a sodium:hydrogen antiporter, which catalyzes the reaction: Na+(out) + H+(in) = Na+(in) + H+(out).

Any process that activates or increases the frequency, rate or extent of kinase activity, the catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.

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 histamine stimulus. Histamine, the biogenic amine 2-(1H-imidazol-4-yl)ethanamine, is involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter.

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.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways involving dopamine.

The chemical reactions and pathways involving dopamine, a catecholamine neurotransmitter and a metabolic precursor of noradrenaline and adrenaline.

The response of an organism to a perceived external threat.

Any process that modulates the frequency, rate or extent of a circadian rhythm. A circadian rhythm is a biological process in an organism that recurs with a regularity of approximately 24 hours.

Any process that results in a change in the behavior of an organism as a result of a cocaine stimulus.

Any process that results in a change in the behavior of an organism as a result of an ethanol stimulus.

The controlled release of arachidonic acid from a cell or a tissue.

Any process that stops, prevents, or reduces the frequency, rate or extent of the controlled release of a protein from a cell.

Any process that activates or increases the frequency, rate or extent of the directed movement of dopamine into a cell.

A process that causes a temporary decrease in postsynaptic membrane potential due to the flow of negatively charged ions into the postsynaptic cell. The flow of ions that causes an IPSP is an inhibitory postsynaptic current (IPSC) and makes it more difficult for the neuron to fire an action potential.

Any process that stops, prevents or reduces the frequency, rate or extent of voltage-gated calcium channel activity.

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

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

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
