Coding of FM sweep trains and twitter calls in area CM of marmoset auditory cortexYoshinao Kajikawa
Department of Psychology, Vanderbilt University, United States
Hear Res 239:107-25. 2008..This suggests that CM could be engaged in processing that requires relatively precise temporal envelope discrimination, and supports the hypothesis that CM is positioned at an early stage of processing in the auditory cortex of primates...
Anatomical organization of the auditory cortexTroy A Hackett
Department of Hearing and Speech Sciences, Department of Psychology, Vanderbilt University School of Medicine, Nashville, TN 37203, USA

Department of Hearing and Speech Sciences, Vanderbilt University School of Medicine, Nashville, TN 37203, USA
J Chem Neuroanat 38:106-16. 2009..These chemoarchitectonic features are likely to subserve regional differences in neuronal activity between regions of auditory cortex... - Sources of somatosensory input to the caudal belt areas of auditory cortexTroy A Hackett
Department of Hearing and Speech Sciences, Vanderbilt University, Nashville, TN 37203, USA
Perception 36:1419-30. 2007..The present data add to growing evidence of multisensory convergence in cortical areas previously considered to be 'unimodal', and also indicate that auditory cortical areas differ in this respect... - Multisensory convergence in auditory cortex, II. Thalamocortical connections of the caudal superior temporal planeTroy A Hackett
Department of Hearing and Speech Sciences, Vanderbilt University, Nashville, Tennessee 37203, USA
J Comp Neurol 502:924-52. 2007..Somatosensory inputs may reach CM and CL through MGm or the multisensory nuclei but not VP... - VGLUT1 and VGLUT2 mRNA expression in the primate auditory pathwayTroy A Hackett
Dept of Hearing and Speech Sciences, Vanderbilt University School of Medicine, Nashville, TN 37203, USA
Hear Res 274:129-41. 2011..The results also suggest that VGLUT mRNA expression patterns in primates are similar to rodents, and establish a baseline for detailed studies of these transporters in selected circuits of the auditory system... - Neurosurgical access to cortical areas in the lateral fissure of primatesTroy A Hackett
Department of Hearing and Speech Sciences, Vanderbilt University, 301 Wilson Hall, 111 21st Avenue South, Nashville, TN 37203, USA

Department of Psychology, Vanderbilt University, Nashville, Tennessee 37203, USA
J Comp Neurol 496:72-96. 2006..The results indicate that parallel subcortical pathways target the core and medial belt regions and that RM and CM represent functionally distinct areas within the medial belt auditory cortex... - Cortical connections of the auditory cortex in marmoset monkeys: core and medial belt regionsLisa A de la Mothe
Department of Psychology, Vanderbilt University, Nashville, Tennessee 37203, USA
J Comp Neurol 496:27-71. 2006..CM also has somatosensory input and may correspond to an area on the posteromedial transverse gyrus of humans and the anterior auditory field of other mammals... - A comparison of neuron response properties in areas A1 and CM of the marmoset monkey auditory cortex: tones and broadband noiseYoshinao Kajikawa
Department of Psychology, Vanderbilt University, 301 Wilson Hall 111 21Avenue South, Nashville, TN 37203, USA
J Neurophysiol 93:22-34. 2005..Therefore refinements of current models of the primate auditory cortex may be needed to account for differences in organization among the auditory belt areas... - Entropy analysis of neuronal spike train synchronyYoshinao Kajikawa
Department of Psychology, Vanderbilt University, 301 Wilson Hall, 111 21st Avenue South, Nashville, TN 37203, USA
J Neurosci Methods 149:90-3. 2005..In this report, we propose a new method to quantify synchrony, applicable to both unimodal and multimodal distributions. We also propose a statistical test to examine temporal structure under a null hypothesis of no synchrony... - Fluorescent retrograde axonal tracing of the facial nerveMatthew R O'Malley
Vanderbilt University Department of Hearing and Speech Sciences, Nashville, Tennessee, USA
Laryngoscope 116:1792-7. 2006..The objective of this study was to investigate retrograde fluorescent axonal labeling of motor nerves as an aid to surgical dissection in otolaryngology-head and neck surgery... - Multisensory convergence in auditory cortex, I.
