The building also contains a fully functioning trial courtroom used for moot court.
To determine whether the firing rate of a neuron exhibits a significant trend of change before the estimated learning trial, Poisson regression fits of second (Figs. 2A, 7A) and first (Figs. 2B, 7D) order polynomials are fit to the data as a function of trial number at trials before the estimated learning trial.
The value at the next to last timestep in a trial, as a function of trial number (with initial values taken to be zero), is where r(t) is the reward at the end of trial t.
Here we compare three GLMs in their efficiency for estimating average and individual Betas across trials as a function of trial variability, scan noise and Stimulus Onset Asynchrony (SOA): "Least Squares All" (LSA), "Least Squares Separate" (LSS) and "Least Squares Unitary" (LSU).
As expected, peak object roll changed significantly as a function of trial (main effect of Trial: F(11,18) = 9.497, p<0.01).
Data in our study were analyzed by modeling nose poking as a function of trial time at the single trial level as a three-state system (break → run → break).
To detect more subtle changes over rapid timescales, we plotted average Purkinje cell firing during the first 100 ms of each trial of a given training session as a function of trial number (typically, 30 40 individual vestibular stimuli, or trials, in a given direction made up a single session) (see examples in Figure 4A).
For example, one might predict that individuals with greater structural integrity in white matter tracts should have a larger dynamic range of activation, and might therefore show greater modulation of white matter BOLD as a function of trial-by-trial RT differences.
However, the performance curves run nearly parallel as a function of trial, thus suggesting that the rate of learning object roll minimization may be similar in both subject groups (but see below).
The PI trials last longer than the FI trials and the reinforcement is omitted; the timing performance of the mice are evaluated based on response rates as a function of trial time (Fig. 4b).
Beacon use varied as a function of trial number, as verified in a within-participants analysis of variance (ANOVA), F 39, 1911) = 13.45, p < 0.001, η2 = 0.22.
