@@Home -> BiologicalLifeResearch -> BrainCenterFD_TH_CR

This page covers biological details of component group Cognitive Thalamus. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Forebrain Diencephalon -> Thalamus (FD.TH) -> Cognitive Thalamus (FD.TH.CR) (see Mind Maps)
• Function: Relay conginitive activity

Components

(generated)

Component items:

• Mediodorsal Nucleus of Thalamus (FD.TH.MD): Attention, planning, organization, abstract thinking, multi-tasking, and active memory
  • Medial Mediodorsal Nucleus of Thalamus (NDM.FD.TH.MDM): relay emotional attention to orbitofrontal cortex
  • Central Mediodorsal Nucleus of Thalamus (NCP.FD.TH.MDC): relay olfactory neocortex to insular integrated neocortex
  • Lateral Mediodorsal Nucleus of Thalamus (NMA.FD.TH.MDL): relay tegmentum to dorsal cingulate cortex
• Anterior Nucleus of Thalamus (FD.TH.AN): Extended hippocampal system
  • Anteromedial Nucleus (NCP.FD.TH.AM): feed-forward HF to PFC
  • Anteroventral Nucleus (FMM.FD.TH.AV): return loop to convey theta to HF, attentional processes
  • Anterodorsal Nucleus (FMM.FD.TH.AD): head direction, spatial learning and memory
• Intralaminar and Midline Nuclei of Thalamus (FD.TH.IML)
  • Intralaminar Nuclear Group of Thalamus (FEC.FD.TH.IL): Projects from SC LVII,LVIII and Spinal Trigeminal Nucleus to striatum
    • Rostral Intralaminar Nuclear Group of Thalamus (FEC.FD.TH.RIL): cognitive functions
    • Caudal Intralaminar Nucleus of Thalamus (FEC.FD.TH.CIL): Stimulate memory-guided response
      • Centromedian Nucleus of Thalamus (FEC.FD.TH.CM): Control of level of cortical activity
      • Parafascicular Nucleus of Thalamus (FEC.FD.TH.PF): Stimulation of acetylcholine release in dorsal striata
  • Midline Nuclear Group of Thalamus (FD.TH.MTH)
    • Dorsal Midline Nuclear Group of Thalamus (FD.TH.MDT): viscero-limbic functions
      • Paratenial Nucleus of Thalamus (FAM.FD.TH.PT): Gateway for multimodal information to limbic system used in selecting appropriate responses
      • Paraventricular Nucleus of Thalamus (LPC.FD.TH.PV): Direct behavior toward a particular outcome over a range of outcomes
    • Ventral Midline Nuclear Group of Thalamus (FD.TH.MVT): multimodal sensory processing functions
      • Reuniens Nucleus of Thalamus (FMM.FD.TH.RE): Gate information between OMPFC and HC dependent upon attentive/arousal states
      • Rhomboidal Nucleus of Thalamus (FMM.FD.TH.RH): Communication of information across memory delays to guide memory responses
      • Subfascicular Nucleus of Thalamus (LLC.FD.TH.SF): Relays from PAG to Rhape nuclei, Inferior olive nucleus
