Abstract

The corticocortal projection from area 3a to area 4γ was restudied using tranquilized cats. Intracortical microstimulation (ICMS) of a given locus in area 3a produced effects of neurons in area 4γ that were located in a small area extending along the direction of the radial fibers constituting a columnar shape. Cortical neurons in area 3a that projected to a particular neuron in area 4γ were located in a region that extended along the direction of the radial fibers and constituted a columnar shape. Two-thirds of the projection neurons in area 3a had different receptive fields from those of neurons in the projected area in 4γ, thus suggesting that the 3a neurons are not simply transferring information to the 4γ neurons. ICMS delivered to area 3a rarely excited 4γ neurons but rather facilitated their evoked discharges. It is suggested that the activity of corticocortical projection from area 3a to 4γ can influence the activity of 4γ neurons only when combined with other inputs to the motor cortex.
