Response to Stimulus

Detection of and Response to Stimulus

Terms and Structure

The response of a cell or an organism to a stimulus is all the processes that occur as a result of the stimulus occurring within or outside the cell or organism. Detection of the stimulus, the process in which a stimulus is received by a cell and converted into a molecular signal, is thus a class of stimulus response. The general structure of this node is as follows:

response to stimulus
[i] detection of stimulus
---[i] detection of stimulus type stimulus
[i] response to stimulus type stimulus
---[i] detection of stimulus type stimulus
---[i] [examples of processes which occur in response to stimulus type stimulus]

There may be different types of response to a stimulus, such as cellular or behavioral responses. The structure for these terms would be:

response to stimulus type stimulus
[i] behavioral response to stimulus type stimulus
[i] cellular response to stimulus type stimulus

Note that sensory perception is a special class of response to stimulus; please see the sensory perception documentation. The phrase perception of xxx should only be used in names or definitions of terms relevant to organisms capable of performing neural processing of the signal generated by the stimulus, but xxx sensing is considered by GO to be synonymous with detection of xxx.

Standard Definitions

response to stimulus type stimulus
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 stimulus type stimulus.
cellular response to stimulus type stimulus
A change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus type stimulus.
behavioral response to stimulus type stimulus
A change in the behavior of an organism as a result of a stimulus type stimulus.
age-dependent response to stimulus type stimulus
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 stimulus type stimulus, where the change varies according to the age of the cell or organism.
detection of stimulus type stimulus
The series of events in which a chemical stimulus is received and converted into a molecular signal.
