  • Processing sensory information related to touch, pressure, and temperature (correct)

    • Which pathway is involved in transmitting sensory information to the cerebral cortex?

  • Relay nucleus pathway
  • Cerebellar pathway
  • Brain stem pathway
  • Midline Ventrolateral spinothalamic tract (correct)

    • What is the function of the thalamus in the sensory system?

  • Regulating motor functions
  • Processing visual stimuli
  • Relaying sensory information to the cerebral cortex (correct)
  • Controlling olfactory perception
