Components

(generated)

Component items:

• Cochlear Nucleus (LPC.HL.COCH): Divergence in representation of auditory information
  • Dorsal Cochlear Nucleus (LPC.HL.DCOCH): Analyzes quality of sound, picks apart tiny frequency differences between close sounds
  • Ventral Cochlear Nucleus (LPC.HL.VCOCH): determine direction sound came from, time-sensitive localization
• Trigeminal Sensory Nuclei (HL.TGS)
  • Spinal Trigeminal Nucleus (LPC.HL.TGS.STR): Discriminative sensation and light touch of face, conscious proprioception
  • Paratrigeminal Nucleus (LRC.HL.TGS.PA5): Orofacial nociceptive sensory processing
  • Peritrigeminal Nucleus (LAC.HL.TGS.PE5): Thermoregulation
• Spinal Sensory Nuclei (HL.SS)
  • Dorsal Column Nuclei (HL.SS.DCN)
    • Cuneate Nucleus (LPC.HL.CU): Carry fine touch and proprioceptive information from upper body
    • Gracile Nucleus (LPC.HL.GR): Carry epicritic, kinesthetic, and conscious proprioceptive information from lower body
  • Accessory Cuneate Nucleus (LPC.HL.ACU): receives input from cervical spinal nerves and transmits that information to cerebellum
  • Inferior Olivary Nucleus (LLC.HL.IO): Proprioception Relay from Spinal Cord to Cerebellum
• Solitary Nucleus (LPC.HL.SOL): Carry taste buds, thoracic and abdominal viscera
• Arcuate Nucleus of Medulla (LLC.HL.ARC): Relay cardiorepriratory proprioception to cerebellum
