Airplane! watch as "Otto" takes control of the plane, inflates a female companion, and takes off. Jerry Zucker, Jim Abrahams, and David Zucker (collectively known as Zucker, Abrahams and Zucker, or ZAZ), wrote "Airplane!" while they were performing with the Kentucky Fried Theatre, a small theatre they had founded in 1971. To obtain material for comedy routines, they routinely recorded late night television and reviewed the tapes later primarily to pull the commercials, a process Abrahams compared to "seining for fish". During one such taping process, they unintentionally recorded the 1957 film "Zero Hour!", and while scanning the commercials, found that
Spike-triggered covariance the mean stimulus from each vector. The spike-triggered covariance (STC) is given by where formula_6 is the total number of spikes, and STA is the spike-triggered average. The covariance of the stimulus is given by where formula_8 is the number of stimuli formula_1 used during the experiment. The eigenvectors of formula_10 associated to significantly positive eigenvalues correspond to excitatory vectors, whereas eigenvectors associated to significantly negative eigenvalues are inhibitory eigenvectors. Matlab code for STA/STC analysis of neural data Spike-triggered covariance Spike-triggered covariance (STC) analysis is a tool for characterizing a neuron's response properties using the covariance of stimuli that elicit
