Schaffer collateral-ca1 synapses

WebAlthough the basal synaptic transmission of Schaffer collateral-CA1 neurons was not affected in the knockout mice, we found that there was a modest deficit in LTP evoked by a single train of 100 Hz stimulation, but a greater deficit in LTP evoked by one train of theta-burst stimulation. In contrast, LTP evoked by either four trains of 100 WebAug 8, 2024 · We hypothesize that the rapid antidepressant actions of (2R,6R)-HNK involve an acute increase in glutamate release at Schaffer collateral synapses.
