Cím:	Axon diversity of lamina I local-circuit neurons in the lumbar spinal / Szucs Peter, Luz Liliana, Pinho Raquel, Aguiar Paulo, Antal Zsofia, Tiong Sheena, Todd Andrew J., Safronov Boris
Dátum:	2013
Megjegyzések:	Spinal lamina I is a key area for relaying and integrating information from nociceptive primary afferents with various other sources of inputs. While lamina I projection neurons have been intensively studied, much less attention has been given to local-circuit neurons (LCNs), which form the majority of the lamina I neuronal population. In this work the infrared light-emitting diode (IR-LED) oblique illumination technique was used to visualize and label LCNs, allowing reconstruction and analysis of their dendritic and extensive axonal trees. We show that the majority of lamina I neurons with locally branching axons fall into the multipolar (with ventrally protruding dendrites) and flattened (dendrites limited to lamina I) somatodendritic categories. Analysis of their axons revealed that the initial myelinated part gives rise to several unmyelinated small-diameter branches that have a high number of densely packed large varicosities and an extensive rostrocaudal (2-3 segments), mediolateral and dorsoventral (reaching laminae III-IV) distribution. The extent of the axon and the occasional presence of long solitary branches suggest that LCNs may also form short and long propriospinal connections. We also found that the distribution of axon varicosities and terminal field locations show substantial heterogeneity and that a substantial portion of LCNs is inhibitory. Our observations indicate that LCNs of lamina I form intersegmental as well as interlaminar connections and may govern large numbers of neurons, providing anatomical substrate for rostrocaudal "processing units" in the dorsal horn.

Cím:	Local axon collaterals of lamina I projection neurons in the spinal cord of young rats / Peter Szucs, Liliana L. Luz, Deolinda Lima, Boris V. Safronov
Dátum:	2010
ISSN:	0021-9967
Megjegyzések:	Large, mediolaterally oriented neurons in lamina I of the spinal cord, frequently referred to as marginal cells of Waldeyer, are known to project to supraspinal targets via the anterolateral tract (ALT). Although dendritic organization of lamina I neurons has been extensively studied, little is known about their local axonal morphology and branching. With the help of oblique illumination, we visually identified large lamina I neurons in the isolated lumbar enlargement (L1-L6) of the spinal cord of P14-P20 rats. By using intracellular and cell-attached biocytin injections, we achieved extensive axonal and dendritic labeling in 77 lamina I cells, 40 of which were identified as ALT projection neurons. In the majority of the cases (n = 28), the main axon of these projection neurons gave rise to one or more thin collaterals on the ipsilateral side. Based on their trajectory and location, these collaterals could be divided into three major categories: dorsal, lateral, and ventral. Lamina I projection neurons had dorsal (n = 5), lateral (n = 8), or ventral (n = 6) collaterals only or a combination of these collateral types (n = 9). Our results suggest that lamina I ALT projection neurons can additionally function as local-circuit and propriospinal neurons participating in intra- and intersegmental spinal cord processing.
