Characterization of neurons in the CA2 subfield of the adult rat hippocampus. Mercer A, Trigg HL, Thomson AM J Neurosci, 2007 Jul 4, 27 (27), pages: 7329 - 7338 PMID: 17611285; DOI: 10.1523/JNEUROSCI.1829-07.2007 |
 "Figure 4. Dendritic and axonal patterns of bistratified cells recorded and filled in the CA1 and CA2 regions... Ba, Reconstruction of a CA2 bistratified cell {CA2 Bistratified} using a drawing tube. This cell presented a narrow dendritic arbor (in black) that extended from SO to SR without entering SLM. The axon (in red) was strongly polarized and arborized mainly in SO and SR of CA2 and CA1 but did not enter CA3. The bistratified cell was CCK [cholecystokinin] immunonegative ... Ca,Reconstruction of another CA2 bistratified cell. This interneuron presented a broad dendritic arbor (in black) that extended to the CA1 and CA3 regions. The axonal arbor of this bistratified cell (in red) was strongly polarized ramifying in SO and SR of the CA2 and CA1 regions but not CA3." |
