AMPA-type glutamate receptors are necessary for evoked coiling. (A) Frequency of the spontaneous coils, (B) kinetic analysis of the touch response, and (C) failure rate after injection of embryo medium (control), AMPA receptor, or NMDA receptor antagonists (CNQX and MK801, respectively). Stacked bars in B are cumulative, thus also representing the duration for the entire behavior. The number of movements analyzed is indicated in each column in B, whereas the number of embryos analyzed is indicated in each column in A and C (error bars = s.d.).
