  • Summary of paired recording experiments. ″Synaptic connections″ refers to the number of connections observed in the direction specified by ″Synapse type.″ p refers to the probability that a spike in the presynaptic neuron resulted in an IPSP/IPSC in the postsynaptic neuron. Numbers in parentheses refer to the n of connections that each p value is based on. ″Onset latency″ refers to delay between the peak of the presynaptic spike and the onset of the IPSC.
