Emerson M. Pugh once wrote that "If the human brain were so simple that we could understand it, we would be so simple that we couldn’t." We imagine Dr. Daniel Pierce, the eccentric crime-solving neuroscientist on TNT’s latest crime drama, Perception, would agree.

We're also curious how Dr. Pierce might weigh in on the perception-altering images below. These optical illusions are definitely not GIFs. Click through below to see the illusions, and don't forget to tune in to the premiere of Perception on Monday, July 9, at 10/9c.

  • Acorn Craziness

    This optical illusion moves in waves as your eye traverses the image.

  • Modulated Diamond Field

    This optical illusion expands and contracts as your eye moves across the screen.

  • Expanding Vortex

    This optical illusion expands and contracts as you focus on different areas of the image.

  • Zebra Roll

    Look closely. This wavy zebra-like pattern gives off the illusion of cylindrical turning.

  • Psychedelic Color Vortex

    This psychedelic color vortex pulsates with a mighty illusoriness.

  • Texture Zoom

    The sharp/fuzzy contrast creates an optical illusion that makes the circle's pattern move when you move your head closer to the image.

  • The Rippling Eye

    This pattern -- which resembles an eye -- sends ripples moving outward from the center.

  • Square Bulge

    This illusion gives off the sense of infinite expansion.

  • Circular Gears

    These overlapping circles give off the impression of gear-like circular movement. Try to make the motion stop.

  • Irregular Circular Vortex

    This vortex moves subtly as the eye travels across the image.

  • Parallel Lines?

    Are these lines parallel or curved?

  • Black Dots

    Try and find the black dots.

  • Dot Rotation

    The circle rotates as you move your head closer to the dot.

  • Spinner

    Look at the columns closely.

  • Grey Area

    Stare at the black dot long enough and watch the grey area disappear.
