Tutorials on Advanced Concepts

Cyanobacteria

Cyanobacterial Circadian Oscillator

This animation demonstrates the circadian oscillator mechanism in the cyanobacterium Synechococcus elongatus. It was produced and developed by members of the BioClock Studio Winter 2016 at UC San Diego.

Cyanobacterial Circadian Clock Output Mechanism

This animation shows how the core circadian oscillator in the cyanobacterium Synechococcus elongatus sends output to regulate the timing of other intracellular processes. It was produced and developed by members of the BioClock Studio Winter 2016 at UC San Diego.

 

Mammalian Systems

Mammalian Retina and Photoreceptors

This tutorial video was produced by members of the BioClock Studio Winter 2016 at UC San Diego and clarifies the anatomy and function of neural circuits for image-forming and non-image-forming vision.

Luciferase Reporters for Mammals in Circadian Research

This video was made by members of the BioClock Studio Winter 2016 at UC San Diego and shows the use of luciferase reporters in mice for circadian research.

The Suprachiasmatic Nucleus: Lesion & Transplant Experiments Review

This video tutorial was produced by members of the BioClock Studio Winter 2017 at UC San Diego. It describes landmark experiments involving SCN lesions and SCN transplants with Tau mutant hamsters, which demonstrated the role of the SCN as the central mammalian pacemaker.

 

Plant Systems

Photoperiodic Flowering - Part 1

This video tutorial was produced by members of the BioClock Studio Winter 2017 at UC San Diego. It describes how plants decide when it’s time to flower based on their ability to precisely measure day- and night-lengths, a phenomenon that is called “Photoperiodic Flowering."

 

Sleep & the Circadian System

2-Process Model of Sleep

This tutorial was produced by members of the BioClock Studio Winter 2016 at UC San Diego, and clarifies how sleep homeostasis and the circadian clock are hypothesized to interact to determine the sleep-wake cycle.
