However, little of our neuroscience knowledge covers the human brain. <strong><span style=\"color: #ff0000;\">Is this organ truly unique, or is it a scaled version of the extensively studied rodent brain?<\/span><\/strong> Combining multicellular patch-clamp recording with expansion-based superresolution microscopy and full-scale modeling, we determined the cellular and microcircuit properties of the human hippocampal CA3 region, a fundamental circuit for memory storage. In contrast to neocortical networks, <strong><span style=\"color: #ff0000;\">human hippocampal CA3 displayed sparse connectivity, providing a circuit architecture that maximizes associational power<\/span><\/strong>. Human synapses showed unique reliability, high precision, and long integration times, exhibiting both species- and circuit-specific properties. Together with expanded neuronal numbers, <strong><span style=\"color: #ff0000;\">these circuit characteristics greatly enhanced the memory storage capacity of CA3<\/span><\/strong>. Our results reveal distinct microcircuit properties of the human hippocampus and begin to unravel the inner workings of our most complex organ.&#8221;<\/p>\n<p style=\"text-align: justify;\">Jake F.
