Figure 7. Interaction of cortex inactivation with disinhibition of dLGN relay cells by Bicu.

Figure 7

Simplified connection scheme of the primary visual pathway, showing the pathways for corticofugal facilitation (S1) or disinhibition (S2) stressed in black. A-L, combination of cooling the cortex and micro-iontophoresis of GABA and Bicu in the dLGN (Y on-cell; flashing spot stimulus; size, 2.5 deg; contrast, 0.9; single ejection barrels, ejection currents in nA, see figure). Recording times: B-D, starting immediately and continuing during drug application; E, immediate recovery after stopping the drug application; F, 28 min; G, 32 min; H, 36 min; I, 40 min; and J, 44 min after cooling onset; K, 15 min; and L, 18 min after termination of cooling. For other conventions see legend of Fig. 2. Total number of intervals n for the complete recordings (A-L): 8495, 4921, 7664, 8555, 8593, 6281, 6795, 7270, 7580, 7334, 8755, 8703.
