    J Comp Neurol 385:245-64. 1997
    ..This dendritic orientation suggests that radiate neurons are sensitive to a broad range of frequencies. These structural differences between planar and radiate neurons suggest that they subserve separate functions in acoustic processing...
  2. ncbi request reprint The source of corticocollicular and corticobulbar projections in area Te1 of the rat
    John R Doucet
    Department of Otolaryngology HNS, Center for Hearing Sciences, Johns Hopkins University School of Medicine, 720 Rutland Avenue, Baltimore, MD 21205, USA
    Exp Brain Res 153:461-6. 2003
    ..Combined with the distinct laminar distribution of IC-, SOC-, and CN-projecting neurons within layer V, the results suggest that these three pathways largely derive from different populations of cortical neurons...

    Exp Brain Res 153:477-85. 2003
    ..Some of these integrative processes begin at the earliest stages of the central auditory system. In this review, we will discuss evidence that reveals multimodal projections into the granule cell domain of the cochlear nucleus...

    J Comp Neurol 459:77-89. 2003
    ..Adendritic neurons have small somata with many filopodial appendages, no observable dendrites, and high percentage of terminal appositions (>80%). The results demonstrated that the ventrotubercular pathway in the rat is diverse...
