stimuluselicited

Stimuluselicited is an adjective used in neuroscience and psychology to describe a behavioral or physiological response that is produced by a specific stimulus. The term emphasizes the causal role of the stimulus and is commonly used to distinguish responses that are directly triggered by stimuli from spontaneous activity that occurs without external input.

In research, controlled stimuli such as light, sound, touch, or cognitive prompts are presented while researchers measure stimuluselicited responses. These responses may be neural, as in stimuluselicited EEG potentials or fMRI activations; physiological, such as autonomic measures like skin conductance or heart rate; or behavioral, such as reaction time, choice, or accuracy. The object of study is often called an evoked response.

Measurement and analysis typically involve averaging across trials to isolate the time-locked response, as in event-related potentials, or modeling brain or body responses that occur consistently following stimulus onset. Experimental design seeks to minimize confounds such as anticipation, habituation, or baseline drift. Techniques include randomized inter-stimulus intervals, proper control conditions, and replication across subjects.

The term is closely related to stimulus-evoked, evoked, and stimulus-evoked responses. It appears across disciplines including cognitive neuroscience, psychophysiology, and sensory psychology, where clear attribution of a response to a stimulus is essential for understanding perception, attention, learning, and emotion.
