Brain Games is an American popular science television series that explores cognitive science by focusing on illusions, psychological experiments, and counterintuitive thinking. The series debuted on National Geographic in 2011 as a special.
Neil Patrick Harris was the unseen narrator in the first season, replaced by Jason Silva for the remainder of the series as its host and presenter; in addition, sleight-of-hand artist Apollo Robbins has been a frequent consultant and illusionist guest on the show. As time passed, Magician Eric Leclerc took over this role in seasons 4 and 5. The show is interactive, encouraging television viewers, often along with a handful of live volunteers, to engage in visual, auditory, and other cognitive experiments, or "brain games", that emphasize the main points presented in each episode. Experts like Sri Sarma also explain why humans react in a certain way because of the brain.
