| Research Abstract |
Three cortical areas (rostral part of the lateral agranular cortex [r-Agl], rostral part of the medial agranular cortex [r-Agm], rostral part of the primary somatosensory cortex [r-S1]) were found to project directly to the three groups of premotoneuron areas around the trigeminal motor nucleus in the rat. The r-Agl and r-Agm had stronger connections with the motor thalamus, while the r-S1 with the sensory thalamus. Electrical stimulation of the r-Agl and r-S1 induced different patterns of jaw movements, while that of the r-Agm induced no jaw movements. The present study indicated that the r-Agl, r-Agm and r-S1 play different roles in jaw movements.
