Ratio of inhibitory inputs on different compartments calculated from total convergence values.A, The ratio of inhibitory synapses on somata was higher than on dendrites for all cell populations. B, Ratio of inhibition versus dendrite thickness. Thinner and thus more remote dendritic regions had a lower percentage of inhibitory terminals than the proximal dendrites in the case of CB and CR cells. A similar trend was seen on PV cells in the case of thick and medium dendrites. The trend broke in the case of thin dendrites, most probably because a large amount of thin dendrites were found in stratum lacunosum-moleculare, where the ratio of inhibition is generally higher. C, The ratio of inhibition in different layers for the three cell types.
