Short Term Memory May Be the Depletion of the Readily Releasable Pool of Presynaptic Neurotransmitter Vesicles

a short response time and an item almost forgotten requires a longer response time.

Figure 1 Response time as a function of the probability of correct recall (1). The time
after stimulus presentation is not shown but short times (from 0 seconds) correspond to high
probability of recall and long times (up to 594 seconds) correspond to low probability of recall.

Figure 2 Response time as a function of the probability of recognition(1). The time after
stimulus presentation is not shown but short times (from 0 seconds) correspond to high
probability of recognition and long times (up to 594 seconds) correspond to low probability of
recognition. The time scale is smaller than the time scale in Figure 1 so the experimental noise
accounts for a larger amount of R².
