'Express saccades: is bimodality a result of the order of stimulus presentation?'

Dopaminergic activity decreases with repeated stimulus presentation.

To eliminate these, fMRI studies repeat a stimulus presentation multiple times.

Temporal resolution can be improved by staggering stimulus presentation across trials.

It is calculated by subtracting the means of all troughs from the means of all peaks experienced during stimulus presentation.

One of the difficulties of traditional tachistoscopic procedures is that of relying on subjects to maintain their fixation during stimulus presentation.

Neurons in sensory regions of the brain respond to stimuli by firing one or more nerve impulses (action potentials) following stimulus presentation.

Since the 1990s, computers running various software packages have automated much of the stimulus presentation and behavioral measurement in the laboratory.

That is, a habituated response to a stimulus recovers (increases in magnitude) when a significant amount of time (hours, days, weeks) passes between stimulus presentations.

After the initial "recovery", responding returns to its habituated level with subsequent stimulus presentations.
