    Anole Lizards: An Example of Speciation

    Animation

    (2 min 38 sec) This animation features the anole lizards as an example of how a single species can split and multiply into many different species with distinct traits.

  • Neurons in parietal cortex are active during straddling

    Neurons in parietal cortex are active during straddling

    Animation

    (1 min 4 sec) Neurons in the cortical area 5 are active when a cat is straddling an obstacle.

  • Leptin Feedback Control System

    Leptin Feedback Control System

    Animation

    (1 min 1 sec) Demonstrates how changes in the amount of fat tissue lead to changes in leptin levels and thus changes in appetite.

  • The Drosophila Molecular Clock Model

    The Drosophila Molecular Clock Model

    Animation

    (7 min 35 sec) Watch these animations display the dynamic orchestration of the molecular events of the Drosophila biological clock.

  • Measuring Circadian Activity in Drosophila

    Measuring Circadian Activity in Drosophila

    Animation

    (2 min 3 sec) This animation series shows four experiments that compare the activity patterns of a wild-type fly keeping a normal schedule with those of a mutant fly apparently following a 19-hour internal clock.

  • The Mammalian Molecular Clock Model

    The Mammalian Molecular Clock Model

    Animation

    (3 min 41 sec) This animation shows the molecular interactions involved in the negative feedback loop responsible for circadian rhythms in mammals.
