Fields: ‘ trials’ , contains trial information, time stamps, eye position, spikes etc. see below. ‘cell id’,  date yymmdd and N(neuron) + a number, ascending in order of recording ‘monkey’ : which monkey ‘reward condition’ see ‘condition code’ below. Shows which types of rewards were delivered during the recording of the neuron, not alle neurons were recorded with random reward and reward omission in the task ‘PC’ several Purkinje cells are in the data set. Rest is DCN ‘video data’ In some cases the monkey was film and tongue, mouth opening, were measured. Data is available in ‘trials’ field. Fields in ‘trials’ Every row is one trial 1 'trial_nr' 2 'condition_code': trial outcome 0 aborted trial (no reward) 1 incorrect (no reward) 2 correct (reward) 3 correct (no reward) 4 no trial; random reward (reward) 3 'direction_C’               1, 3, 5, 7 = 0, 270, 180 ,90 degrees, 0 degrees being to the right on the screen. 4 ephys start, TTL pulse send from eye tracker to ephyse recorder. Is time in ms according to the clock of the eye tracker, can be used to place trials relative to each other in time if necessary. 5 ephys stop, stop ephys recording TTL pulse 6 ‘trial start’ relative to onset fixation 7 ‘trial stop’ relative to onset fixation 8 fix on: fixation onset 9 'cue_start' cue that tell animal to which direction the C be.  Time from fixation onset 10 'cue_stop' offset of cue, Time from fixation onset 11\. 'c_start' onset of c stimulus, Time from fixation onset 12 'c_stop' offset of c stimulus. Time from fixation onset 13 'choice_target' saccade targets appear. Time from fixation onset 14 'reward_start' reward onset. Time from fixation onset 15 'timestamp_el_reward' reward time in eye link clock. Time from fixation onset 16 'eyeX' eye X position fix on, 1 sample is 1ms, fix on at sample/ms 4000. Length of eye trace differs due to different in trial length 17 'eyeY' eye Y position fix on, 1 sample is 1ms, fix on at sample/ms 4000. Length of eye trace differs due to different in trial lengt 18 'triallength' trial duration in ms  19 SS, simple spikes (these are DCN cells, however its called like that because I used to record PCs, spike time aligned to fix on, 4 seconds of spike before and after. In Seconds, so not ms like the times stamps. 20 CS complex spikes: empty in DCN cells, one or two PCs are mixed in. 21'dispChoiceTTL' eyelink time 22 'saccade_landmarks'.

'gap_direction' direction of the opening of the C stimulus, in degrees, 0 is to the right. 25 saccade amplitude, in degrees 26 reward duration, in miliseconds  that the monkey receives juice through the lick spout 27 mouth opening, tracking pixel distance between upper and lower lip, same ass eyeX, sample 4000 is fix on, Data available for only a part of the cells in which the monkey’s face was filmed. 28 'tongue' tracking of the tongue. Sample 4000 is fix on.
description: To study cerebellar activity during visual attention we recorded
 extracellular activity of dentate nucleus (DN) neurons in two non-human
 primates (NHPs). NHPs were trained to read the direction indicated by a
 peripheral visual stimulus while maintaining fixation at the center, and
 report the direction of the cue by performing a saccadic eye movement into
 the same direction following a delay.DN neurons modulated spiking activity
 over the entire time-course of the task, and that their activity often
 bridged temporally separated intra-trial events, yet in a heterogeneous
 manner.  Both NHPs showed different behavioral strategies, which
 influenced the performance. Activity of the DN neurons reflected the
 unique strategies, with the direction of the visual stimulus frequently
 being encoded long before an upcoming saccade Together, our results
 highlight that DN neurons can dynamically modulate their activity during a
 visual attention task, comprising not only sensorimotor but also cognitive
 attentional components.
