From Morphology to Computation: How Synaptic Organization Shapes Place Fields in CA1 Pyramidal Neurons.

ABSTRACT: The synaptic mechanisms driving feature selectivity in specific neuron types remains a fundamental and unresolved challenge in neuroscience. In hippocampal CA1 pyramidal neurons (PNs), the development of place selectivity, manifested as place fields, is believed to result from dendritic integration of spatially distributed inputs combined with behavioral time scale plasticity (BTSP). BTSP involves dendritic spikes that temporally regulate synaptic potentiation and depotentiation. However, the role of excitatory (E) and inhibitory (I) synaptic distributions in the emergence of place specificity in CA1 PNs remains unclear, due to the lack of detailed synaptic reconstructions in vivo. Here, we present full synaptic reconstructions from individual CA1 PNs in the mouse hippocampus, revealing th
