Thalamus Flashcards
Anterior nucleus
Inputs: mammillary bodies and hippocampus
Outputs: Cingulate gyrus
Important for memory, emotion, and visceral responses.
Mediodorsal nucleus
Inputs: olfactory cortex and spinothalamic tract
Outputs: Olfactory / taste inputs go to insular cortex. Other outputs go to dlPFC for working memory, orbitofrontal cortex for decision making, and vmPFC for emotional tone.
Lateral dorsal nucleus
Inputs: Limbic system
Outputs: Cingulate gyrus
Lateral posterior & Pulvinar nuclei
Inputs: superior colliculus, pretectum, retina, and somatosensory cortex
Outputs: association cortex
Important for visual responsiveness / attentiveness and orientation.
Damage causes hemineglect
Ventral lateral (VL) nucleus
Inputs: cerebellum
Outputs: Primary and association motor cortex
Ventral anterior (VA) nucleus
Inputs: globus pallidus and substantia nigra
Outputs: Primary and association motor cortex
VPL
Inputs: medial lemniscus and ALS
Outputs: somatosensory cortex
VPM
Inputs: TTT and STT
Outputs: somatosensory cortex and taste goes to insular cortex
Medial geniculate nucleus
Inputs: inferior colliculus
Outputs: auditory cortex and amygdala
Lateral geniculate nucleus
Inputs: retinal ganglion cells
Outputs: visual cortex and amygdala
Intralaminar / centromedian nucleus
Inputs: globus pallidus, substantia nigra, spinal tracts and reticular formation.
Outputs: motor cortex and striatum
Important for sensation, motor, and arousal
