Anterior Nucleus
Thalamus
part of the limbic system
Receives from hippocampus & hypothalamus and projects to cingulate gurus
Lateral dorsal nuclei
Thalamus
part of limbic system
Ventral anterior nuclei
Thalamus
Cerebellar and basal nuclei motor pathways
Ventral lateral nuclei
Thalamus
Cerebellar and basal nuclei motor pathways
Dorsomedial nucleus
Thalamus
Moods, emotions, behaviors
Lateral posterior nucleus
Thalamus
Learning and interpreting written symbols
Pulvinar
Thalamus
Learning and interpreting written symbols
Ventral posterolateral nucleus
Thalamus
3rd order cell bodies relaying somatosensation (pain/temp, tactile/vibtration) from the contralateral body
Lesion to VPL results in contralateral loss of somatosensation from the body
Medial geniculate body
Thalamus
Cell bodies that are part of the auditory pathway
Lateral geniculate body
Thalamus
3rd order neuronal cell bodies of the visual pathway
projects to the occipital lobe
Ventral posteromedial nucleus
Thalamus
3rd order cell bodies relaying somatosensation (pain/temp, tactile/vibration) from contralateral face
Intralaminar nuclei
Thalamus
Evoke arousal, alertness, and pain
Anterior & Medial Hypothalamus
Control of parasympathetic nervous system
Heat dissipation
Sleep cycle
Posterior & Lateral Hypothalamus
Control of sympathetic nervous system
Heat conservation
Wake cycle
Mammillary Bodies
Controls wake cycle along with posterior hypothalamus
Suprachiasmatic nucleus
Controls circadian rhythm (24 hour biological clock)
Ventromedial nucleus
Hypothalamus
Controls satiety (fullness)
Opposite effect occurs if lesioned
Lateral hypothalamic area
Hypothalamus
Controls feeding (hunger)
Opposite effect occurs is lesioned
Supraoptic and paraventricular nuclei
Hypothalamus
Produced anti-diuretic hormone (ADH) to control water balance via reabsorption in the kidneys and oxytocin for mating/social interactions
Median eminence
Hypothalamus
Controls all other hormones to control female cyclicity and onset of puberty
Preoptic nucleus
Hypothalamus
Regulates reproductive hormones (LH/FSH)
