  • Data are expressed as the percentage of units (absolute number noted in parentheses) displaying significant behavioral correlates from the total number of units recorded (prelesion = 296; unlesioned = 106; postlesion = 127), except for the measures of trial-type specificity and multiple correlates, which are expressed as a percentage of units from the total number of units displaying that specific type of behavioral correlate and the total number of units displaying any correlate, respectively.

  • * Significantly different from both prelesion and unlesioned (p < 0.05).
