Results focus on a negative peak in the ERP that occurs 170 milliseconds after the stimulus onset.

Rather, these types of violations show a large positivity from about 500-1000 ms after stimulus onset, known as the P600.

For example, P50 is a wave with a positive peak at approximately 50 ms following stimulus onset.

They used ERP and analyzed familiarity-based recognition occurring 300-450 milliseconds after stimulus onset in order to predict the participants' decisions.

Type one fires only one spike to the stimulus onset, has low jitter (variability in timing over stimulus presentations), no spontaneous activity, and is the most common type.

Type two fires two to four spikes to the stimulus onset, has increased jitter with subsequent spikes, and has low spontaneous activity.

M cells (transient cells), are active only during stimulus onset and stimulus offset.

P cells (sustained cells), show continuous activity during stimulus onset, duration, and offset.

When the circle was presented before the visual stimulus onset or simultaneously with stimulus offset, recall matched that found when using a bar or tone.

Visual treadle responses by pigeons still occurred with a delay interval of less than 500ms, showing that visual dominance still prevailed when visual stimulus onset was delayed.
