in projection neurons. Blocking of voltage-sensitive Ca 2+ currents transformed the N-shaped voltagedependency into a linear one, indicating activation of calcium-dependent K + currents (IK,Ca). The densities of currents through voltage-sensitive Ca 2+ channels did not differ between the two neuron classes and the voltagedependency of current activation was similar. Projection neurons thus express higher calcium-dependent K + currents. These analyses revealed that the various neurons of the
