Diversity and selectivity of CA1 neuronal responses to different startle stimuli. Spike raster plots and peri-event histograms (time bin, 100 ms) for representative units are shown. In A-F, Top, Middle, and Bottom correspond to air, drop and shake events, respectively. (A) A unit responsive to all three types of startles (general-startle unit). (B) A unit that increased its firing selectively to air blow (air-blow unit). (C) Drop-selective unit. (D) Shake-selective unit. (E) Air- and drop-responsive unit. (F) Drop- and shake-responsive unit. (G) A unit that responded to air blows in both contexts. (H) A unit that responded only in context B. (I) A unit that responded to drop similarly in elevator A and in elevator B. (J) A unit that exhibited a strong drop response only in Elevator B. All histograms use a time bin of 200 ms. Please note the response variability of each individual neuron across the repeating seven trials (y axis). x axis indicates the time scale (seconds). The vertical red lines in spike rasters indicate the time marker for the occurrence of startling events.
