Properties of inhibitory and excitatory synaptic connections between L4 BIns and L4 spiny neurons

Parameter IPSPs (n = 13) mean ± SD EPSPs (n = 6) mean ± SD
Postsynaptic Vm (mV)* -55.0 ± 0.2 -69.7 ± 2.7
PSP amplitude (mV) 0.93 ± 0.81 1.8 ± 1.7
CV of PSP amplitude 0.49 ± 0.25 0.34 ± 0.09
Failure rate (%) 14 ± 17 7 ± 9
Latency (ms)** 0.5 ± 0.1 1.0 ± 0.3
  • IPSPs were recorded at BIn-L4 spiny neuron connections at a membrane potential of -55 mV; EPSP were recorded at reciprocal L4 spiny neuron-BIn connection at resting membrane potential.

  • *Baseline membrane voltage for recording of IPSPs in postsynaptic L4 spiny neurons was set to a potential of -55 mV (see Materials and Methods section). The calculated IPSP amplitude at the resting membrane potential was 0.68 ± 0.82 mV.

  • **P < 0.001.
