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

• Top-down path to center: Forebrain Telencephalon -> Extended Amygdala (FAM.FT.EXTAM) -> Amygdala (FAM.FT.AM) (see Mind Maps)
• Function: Experiencing and recognizing emotions

Components

(generated)

Component items:

• Basolateral Nuclear Complex (FAM.FT.AM.BL): stimulating emotional response
  • Lateral Amygdaloid Nucleus (FAM.FT.AM.LA): plasticity, conditional (neutral stimulus) to specific (taste, smell, visceral) unconditional (positive or negative stimulus) association
    • Dorsolateral Amygdaloid Nucleus (FAM.FT.AM.LADL): conditional stimulus input - high-aggregated visual, auditory and somatic, patterns of perception
    • Ventrolateral Amygdaloid Nucleus (FAM.FT.AM.LAVL): unconditional stimulus input - visual, auditory and somatic, convergence from thalamus
    • Ventromedial Amygdaloid Nucleus (FAM.FT.AM.LAVM): conditional and unconditional convergence to affect polymodal memory formation
  • Basal Amygdaloid Nucleus (FAM.FT.AM.B): enhance explicit memories in hippocampus about emotional situations
    • Parvicellular Basal Amygdaloid Nucleus (FAM.FT.AM.BP): enhance explicit memories in hippocampus about emotional situations
    • Magnocellular Basal Amygdaloid Nucleus (FAM.FT.AM.BM): enhance emotional memories memories in medial prefrontal cortex
  • Accessory Basal Amygdaloid Nucleus (FAM.FT.AM.AB): enhance assotiative memory formation
• Corticomedial Nuclear Complex (FAM.FT.AM.CTM)
  • Cortical Amygdaloid Nucleus (FAM.FT.AM.CO): olfactory processing
    • Anterior Cortical Amygdaloid Nucleus (FAM.FT.AM.COA): olfactory processing - conditional contextual signaling
    • Posterior Cortical Amygdaloid Nucleus (FAM.FT.AM.COP): olfactory processing - unconditional signaling
  • Centromedial Nuclei (FAM.FT.AM.CM): attention and arousal
    • Central Amygdala (FAM.FT.AM.CEA): mediate behavioral responses, link to general aspects of reinforcement; responses to fear stimuli; directing attention and behaviors when salience of competing stimuli is in flux
      • Central Amygdaloid Nucleus, capsular subdivision (FAM.FT.AM.CEC): mediate behavioral responses, link to striatal effect
      • Central Amygdaloid Nucleus, lateral subdivision (FAM.FT.AM.CEL): mediate behavioral responses, link to gustatory and visceral aspects of reinforcement
      • Medial Central Amygdaloid Nucleus (FAM.FT.AM.CEM): mediate behavioral responses, output projections
    • Medial Amygdala (FAM.FT.AM.M): sense of smell and pheromone-processing
      • Medial Anterior Amygdaloid Nucleus (FAM.FT.AM.MEA): olfactory processing
      • Medial Posteror Dorsal Amygdaloid Nucleus (FAM.FT.AM.MPD): reproductive behavior
      • Medial Posteror Ventral Amygdaloid Nucleus (FAM.FT.AM.MPV): defensive behavior
• Intercalated Amygdaloid Nuclei (FAM.FT.AM.ITC): inhibit excessive emotional behavior
