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)
- 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
