The Role of NMDA Receptor Subtypes in Short-Term Plasticity in the Rat Entorhinal Cortex
Figure 1
Short-term facilitation is
mediated by presynaptic NMDA receptors. (a) First 6 responses evoked by a train
of stimuli (3 Hz, 20 seconds) averaged from 3 neurones. (b) Responses ()
were averaged at low frequency and during 3 Hz stimulation. In the presence of
2-AP5, low-frequency responses were unaltered, but facilitation was abolished.
The bar graphs show the mean results from 5 neurones. (c) Similar results were
seen with MK-801. Stimulation artifacts have been partially blanked for
clarity.
