These axons constitute the loop’s first connection, together with the granular cells of the dentate gyrus (Anderson et al., 2007; Amaral & Witter, 1989; see Figure 1.1). From these cells, mossy fibres in turn project to make the loop’s second connection, with the dendrites of the pyramidal cells in area CA3. The axons of these cells divide into two branches. One branch forms the commissural fibres that project to the controlateral hippocampus via the corpus callosum. The other branch forms the Schaffer collateral pathways that make the third connection in the loop, with the pyramidal cells of area CA1 (Ishizuka, Weber & Amaral, 1990). The axons of the cells in CA1 then project to the neurons of the subiculum and of the EC. The receiving portion of the HF thus consists of the dentate gyrus, whereas the sending portion consists of the subiculum (see Figure 1.4). The axons of the large pyramidal neurons of the subiculum then project to the subcortical nuclei via the fimbria, a thin tract of white matter located at the inner edge of the hippocampus. Finally, the information returns to the sensory cortical areas from which it came prior to hippocampal processing. | These axons make the loop’s first connection, with the granule cells of the dentate gyrus.
From these cells, the mossy fibres in turn project to make the loopÂ’s second connection, with the dendrites of the pyramidal cells in area CA3. The axons of these cells divide into two branches. One branch forms the commissural fibres that project to the controlateral hippocampus via the corpus callosum. The other branch forms the Schaffer collateral pathways that make the third connection in the loop, with the cells in area CA1. [...] Lastly, the axons of the cells in CA1 project to the neurons of the subiculum and of the entorhinal cortex. The receiving portion of the hippocampal formation thus consists of the dentate gyrus, while the sending portion consists of the subiculum. The axons of the large pyramidal neurons of the subiculum then project to the subcortical nuclei via the fimbria, a thin tract of white matter at the inner edge of the hippocampus. Lastly, the information returns to the sensory cortical areas from which it came before it was processed by the hippocampus. |
