title: Dendritic arbors of neurons from different regions of the rat thalamic reticular nucleus share a similar orientation.
abstract: Neurons in different regions of the rat thalamic reticular nucleus were labeled with biotin dextran amine and reconstructed. When viewed in coronal section, some neurons had a radial dendritic tree while others had dorso-ventrally elongated arbors. When rotated, all the neurons had a planar, disc-shaped dendritic field with the dendrites orientated parallel to the long axis of the nucleus. We conclude that all thalamic reticular nucleus neurons have a similar dendritic morphology and orientation.
