在大鼠听皮层脑片上进行光学成像，以研究水平激发如何在大脑皮层中传播。当在颗粒上层和颗粒下层之间进行水平切割时，电刺激II/III层在颗粒上层中以与切割前相同的传播速度在颗粒上层中引起水平传播激发。电刺激VI层或白质与VI层之间的交界处，也在颗粒下层以与切割前相同的传播速度引起水平传播兴奋。这些结果表明，激发在颗粒上层和颗粒下层的水平传播可以独立地发生在听觉皮质中。(C)1999年，Lippincott Williams&Wilkins。
OPTICAL imaging was conducted in rat auditory cortex slice preparations to study how horizontal excitation propagates in the cerebral cortex. When a horizontal cut was made between supragranular and infragranular layers, electrical stimulation of layer II/III elicited horizontally propagating excitation in supragranular layers with the same propagating velocities as those seen before a cut was made. Electrical stimulation of layer VI or the border between the white matter and layer VI also elicited horizontally propagating excitation in infragranular layers with the same propagating velocities as those seen before a cut was made. These results suggest that the horizontal propagation of excitation in supragranular and infragranular layers can occur independently in the auditory cortex. (C) 1999 Lippincott Williams & Wilkins.
