Broadly tuned FS cell. (A) Spike response PSTH for the 16 directions. (B) Membrane potential average for the 16 directions. Resting membrane potential was −74 mV. (C) Von Mises fits to the spiking and synaptic responses. For the spiking response, the high RURA value (62%) and the large HWHH for the tuned response component (45 deg) indicate this cell was weakly orientation selective. The synaptic response was even less selective (RURA: 71%, HWHH: 47 deg).
