MEA RECORDINGS
LTD - LTP in hippocampal slices
Between 1 and 20 Hz, the stimulations train
induces Long-Term Depression (LTD) of evoked-
responses.
At 100 Hz and 200 Hz, the stimulations train
induces Long-Term Potentiation (LTP) of evoked-
responses.
Stimulation trains with a wide range of frequencies (from 1 to 200 Hz) provide a means to
determine the LTD/LTP “crossover point”.

Phenobarbital induced a stable reduction
of the ED frequency over a 2.5 hours
recording period (orange trace).
Application of a new AED (cpd x, for 3
concentrations), with Phenobarbital, is
examined over the same period (blue
trace).
50 µM 4-AP rapidly triggers EDs which
stabilizes around 0.4 Hz. Then, application
of increasing concentration of
Phenobarbital shows a dose-response
decrease of the ED frequency.

MEA RECORDINGS
Tg2576 model profiling
The strength of synaptic transmission is significantly lower in WT than in Tg2576 mice.
The paired-pulse facilitation is significantly impaired in Tg2576, especially for the shortest inter-
stimulus intervals.
The LTP amplitude is significantly altered in Tg2576, compared to that in WT mice.
