The series of events required for a bitter taste stimulus to be received and converted to a molecular signal.

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.

The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The sequence of reactions within a cell required to convert absorbed photons into a molecular signal.

Behavior that is dependent upon the sensation of a mechanical stimulus.

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 heat stimulus, a temperature stimulus above the optimal temperature for that organism.

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 heat stimulus, a temperature stimulus above the optimal temperature for that organism.

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 light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.

The process in which the circadian clock maintains robust and accurate timing over a broad range of physiological temperatures. The circadian clock is an endogenous 24-h timer found in most eukaryotes and in photosynthetic bacteria. The clock drives rhythms in the physiology, biochemistry, and metabolism of the organisms.

The process in which an activated neuronal cell receptor conveys information down a signaling pathway, resulting in a change in the function or state of a cell. This process may be intracellular or intercellular.

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 heat stimulus, a temperature stimulus above the optimal temperature for that organism.

Behavior that is dependent upon the sensation of temperature.

The directed movement of a motile cell or organism in response to a temperature gradient. Movement may be towards either a higher or lower temperature.

The directed movement of a cell or organism away from a source of light.

Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling.

The series of events in which a temperature stimulus is received and converted into a molecular signal as part of thermoception.

The series of events in which a temperature stimulus is received and converted into a molecular signal as part of thermoception.

The series of events involved in the perception of pain in which a temperature stimulus is received and converted into a molecular signal.

The series of events involved in the perception of pain in which a temperature stimulus is received and converted into a molecular signal.

The series of events involved in the perception of pain in which a chemical stimulus is received and converted into a molecular signal.

The component of a 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.

An ion channel complex through which cations pass.
