Show Answers:

  1. Hippocampus deals with
    • Memory
    • Corpus striatum deals with
    • Motor control
  2. Less specific (association) nuclei
    • Anterior and lateral
    • Medial
    • Posterior group
    • Pulvinar
  3. Anterior and Lateral Nuclei
    • Input-Output: prefrontal cortex (Area 9,10,11,12), hypothalamus, hippocampus, and limbic system, especially limbic gyrus. These connections are important for basic drives for food, shelter, and sex
    • Function:
    • ----1. Carry info to and rom limbic system
    • ----2. Through hippocampus where they store our reactions to used in future
    • ---- 3. Through hypothalamus- autonomic responses that accompany emotional responses; lateral nucleus gets info from superior nucleus (visual input --> area 8 (ocular muscles) and area 17(calcarine cortex) --> area 18 interpretation)
  4. Medial nucleus
    Input: somatic sensory input from cerebral cortex (area 9,10,11,12), hypothalamus, hippocampus, corpus striatum, limbic system (amygdala)
  5. Medial nucleus prefrontal cortex (area 9,10,11,12) and limbic system
    Emotional responses and reactions to external and internal environment expressed in various moods, feelings and behaviors that make up our personality
  6. Medial nucleus hypothalamus
    Autonomic responses accompanying moods and feelings as expression of emotional responses to internal and external environment
  7. Medial nucleus hippocampus
  8. Medial nucleus corpus striatum
    Facial expression to express feelings and emotions
  9. Posterior group nuclei
    Input: receives info dealing with pain from lateral spinothalamic tract and 5th CN and shades with other areas of CNS to allow for total comprehensive perception of pain. Also carries info to hypothalamus dealing with autonomic activity in regard to emotional responses dealing with incoming sensory input
  10. Areas that work with hypothalamus in regard to autonomic activity of emotional responses
    • 1. habenuclar nuclei-deals with all emotional response
    • 2. Anterior and lateral nuclei- deal with autonomic activity of 3 basic drives: food, shelter, sex
    • 3. Medial nuclei- deal with autonomic responses corresponding to all emotional responses from internal and external environment
    • 4. Posterior group nuclei- deals with emotional responses to incoming sensory input
    • 5. interpendicular nuclei of reticular formation- carry info dealing with autonomic info of internal and external environment
  11. Pulvinar nuclei
    Have connections with all association areas which allows for total conceptualization at that time
  12. Nonspecific nuclei (other thalamic nuclei)
    • Intralaminar nuclei
    • Reticular nuclei
  13. Intralaminar nuclei
    • Through its connections with reticular nuclei, play an important role in reticular activating system
    • Through connections with corpus striatum, minor role in motor control
    • Responsible for conscious awareness of specific, non specific, touch/ pressure, pain/ temp, vibration, auditory input
  14. Reticular nuclei
    Receive info going to and from thalamus so that it knows the exact state of thalamic activity so if higher centers want to regulate that activity they send commands here
