The Role of NMDA Receptor Subtypes in Short-Term Plasticity in the Rat Entorhinal Cortex
Figure 3
Progressive changes associated with repeated episodes of stimulation at 3 Hz in the absence of NMDAr blockers. Each point is the degree of facilitation recorded during a 30-second
period of stimulation and is the average from 5 neurones. (a) After an initial
decline in the degree of facilitation, it remained stable throughout the
subsequent 30 minutes of recording. (b) Mean amplitude of responses recorded at
low and high frequency used to assess the facilitation in the neurones shown in
(a). There was a progressive, albeit small increase in amplitude of responses
in both cases. Representative records from one neurone, sampled at the times
indicated, are shown below.
