Thalamic nuclei Flashcards
What type of nuclei receive and convey infor from all sensory systems (except olfactory), BG, cerebellum to cortex
Relay Nuclei
What are the types of Relay Nuclei?
Ventral anterior Ventral lateral Ventral posterolateral Ventral posteromedial Medial Geniculate Lateral Geniculate
What type of Nuclei processes emotional and some memory information integrating sensation?
Association Nuclei
What type of Nuclei connect reciprocally to large areas of the cortex?
Association Nuclei
What are the types of Association Nuclei?
Medial group Anterior Lateral Dorsal Lateral Posterior Pulvinar
What are the types of Non specific nuclei of the thalamus?
Intralaminar
Reticular
What type of Nuclei receives sensory from the body
Ventral Posterolateral
What type of Nuclei is associated with spinothalamic/medial lemniscus and sends info to somatosensory cortex?
Ventral Posterolateral
What type of Nuclei receives sensory from the face?
Ventral Posteromedial
What type of Nuclei follows the path of trigeminal nerve to the somatosensory cortex?
Ventral Posteromedial
What type of Nuclei gives us sensations of touch, pain, temp, itch?
VPL or VPM depending on if from face or body
What type of Nuclei is associated with hearing?
Medial Geniculate
What type of Nuclei is associated with sound frequency, intensity, and binaural information?
Medial Geniculate
What type of Nuclei is associated with vision?
Lateral Geniculate
What type of Nuclei is associated with coordination?
Ventral lateral
What type of Nuclei is association with execution of movement/motor learning
Ventral lateral
Damage to this Nuclei can cause memory loss, inability to form new memories, loss of executive functions
Anterior Group
What type of Nuclei is associated with modulation of alertness; learning and episodic memory
Anterior Group
Damage to this nuclei causes problems in the sleep/wake cycle.
Reticular Nuclei
This is an ascending reticular system responsible for arousal and attention.
Intralaminar Nuclei
Damage to this nuclei causes word finding and spatial neglect.
Pulvinar
Damage to this nuclei can cause personality changes; drowsiness and coma
Medial Group
What type of Nuclei is involved in spatial learning and memory?
Lateral Dorsal
What type of Nuclei processes sensory info important to visually guide behavior?
Lateral Posterior
What type of Nuclei regulates consciousness, arousal, attention by projecting to widespread areas of the cortex?
Nonspecific Nuclei
What type of Nuclei has reciprocal connections with areas of the cortex involved in emotions?
Medial Group
What type of Nuclei adjust thalamic activity; interconnects throughout thalamus?
Reticular Nuclei
The only thalamic nucleus that does not project to the cerebral cortex.
Reticular Nuclei
What type of Nuclei is involved with the initiation of movement and motor planning?
Ventral Anterior
Damage to this nuclei causes problems with the regulation of which signals get “attended to” in the thalamus.
Reticular Nuclei
