The purpose of this study is to evaluate the effect of lasmiditan on simulated driving performance in healthy participants. Participants are expected to complete each of four study periods, which will last a total of about 10 days. During this time, participants will remain in the clinical research unit. Screening must be completed within 28 days before the start of the study. Follow-up will be completed about one week after discharge.

Simulated Driving Performance in Healthy Participants as Measured by Standard Deviation of Lateral Position (SDLP) Using the Cognitive Research Corporation Driving Simulator-MiniSim (CRCDS-MiniSim)
The standard deviation of lateral position (SDLP) is the primary parameter used as stable measure of driving performance with high test-retest reliability. It measures the driver's ability to stay in a constant position within the driving lane. LS Means were analyzed using a mixed repeated measures model with fixed effects for sequence, period, and treatment, with repeated observations for subjects for each of the driving time points.
Time frame: 8 hours postdose in each dosing period

Karolinska Sleepiness Scale (KSS) Score
The KSS is used to assess subjective level of sleepiness. This is a participant self-report measure of situational sleepiness and provides an assessment of alertness/sleepiness at a particular point in time. It is a 9-point categorical Likert scale on which the participant rates sleepiness from 1 (very alert) to 9 (very sleepy/fighting sleep), with higher scores indicating more sleepiness and lower scores indicating more alertness.

Number of Correct Responses in Driving Performance Using CogScreen Symbol Digit Coding (SDC) Test
The SDC Test, a digit symbol substitution test that is sensitive to changes in information processing speed, provides measures of response speed and accuracy. The test was administered prior to the simulated driving sessions. The principal test score measures the number of correct responses in 120 seconds. SDC was used in this study to measure attention, visual scanning, working memory, and speed of information processing. A measure of recall accuracy A higher score indicates greater processing speed

Total Number of Collisions
Total collisions are the sum off collisions with other vehicles and off-road crashes. Collision counts also included the number of times that a lane deviation exceeded 4 feet but where no collision occurred ( a crash-likely event).
