Figure 2.

Axonal properties of PFs are not affected by L-AP4. Parallel fibre prevolleys and field excitatory postsynaptic potentials of Purkinje cells were recorded extracellularly with glass micropipettes placed into the lower ⅓ of the molecular layer in transverse slices. PFs were stimulated with 0.05 Hz. (a) Group data for nine experiments showing that the amplitude and the time-course of PF prevolleys are not affected by L-AP4 while PC field EPSP amplitudes are reduced. (b) Superimposed extracellular recordings from one experiment. Each trace represents an average of three sweeps. The pre-stimulation baseline is shown as dashed line. The prevolley is marked with the solid black square, the field EPSP is marked with the striped square. NBQX 10 μM.
