WHITE MATTER THAT SEPARATES THE THALAMUS AND THE HEAD OF CAUDATE MEDIALLY AND PUTAMEN AND GLOBUS PALLIDUS LATERALLY
PYRAMIDAL DECUSSATION
THE CROSSING AREA ON THE SPINAL CORD OF AN UPPER MOTOR NEURON DESCENDING FROM THE MOTOR CORTEX
SPINOTHALAMIC TRACT
ASCENDING TRACT. CONVEYS PAIN, TEMPERATURE, CRUDE TOUCH
ANTERIOR HORN
LOWER MOTOR NEURONS
POSTERIOR DORSAL COLUMNS
ASCENDING TRACT. CONVEYS PROPRIOCEPTION, VIBRATION SENSE, AND FINE DISCRIMINATIVE TOUCH
AMYGDALA
PART OF THE LIMBIC SYSTEM. ESSENTIAL IN EMOTIONS AND DRIVES
