Single unit activities of Y, X and W cells were recorded in the cat lateral geniculate nucleus to study how their responses to stationary light spots change with the cortical EEG. The shift from desynchronized to synchronized EEG drastically suppressed W cell activities, depressed both transient and sustained components of X cell responses, but did not affect the transient component of Y cell responses. This was ascribed to different inhibitory circuitries in the three parallel pathways and their differential modulation by the ascending brainstem activities.
在猫的外侧膝状核中记录了Y、X和W细胞的单单位活动,以研究它们对静止光斑的反应如何随皮层脑电图变化。脑电图从去同步化转变为同步化时,W细胞活动被大幅抑制,X细胞反应的瞬态和持续成分均受到抑制,但不影响Y细胞反应的瞬态成分。这归因于三条平行通路中不同的抑制性回路以及它们受脑干上行活动的不同调制。
