Summary
Understanding the Drosophila circadian circuit requires observing heterogeneous clock neurons. In vivo calcium imaging allows long-term monitoring of these neurons, advancing our knowledge of internal clocks and rhythmic behaviors.
Area of Science:
- Neuroscience
- Chronobiology
- Systems biology
Background:
- The Drosophila circadian circuit is a well-studied but complex neural network.
- Rhythmic behaviors depend on interactions among diverse clock neurons across the brain.
Purpose of the Study:
- To review advancements in interrogating the circadian circuit.
- To highlight the role of in vivo calcium imaging in observing neural activity.
Main Methods:
- Review of existing literature on circadian circuit research.
- Focus on in vivo calcium imaging techniques for long-term neural activity monitoring.
Main Results:
- In vivo calcium imaging enables observation of individual neuron activity over extended periods (hours to days).
- This technique facilitates the study of coordinated network interactions within the circadian circuit.
Conclusions:
- Progress in in vivo calcium imaging is crucial for understanding the complexity of the Drosophila circadian circuit.
- Direct observation of neural activity is key to deciphering the mechanisms underlying rhythmic behaviors.

Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.
Input signals typically originate from voltage or current sources, with the output often representing voltage across the capacitor and/or current through the inductor. For example, in...

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

First-order electrical circuits, which comprise resistors and a single energy storage element - either a capacitor or an inductor, are fundamental to many electronic systems. These circuits are governed by a first-order differential equation that describes the relationship between input and output signals.
One common example of a first-order circuit is the RC (resistor-capacitor) circuit. These circuits are used in relaxation oscillators such as neon lamp oscillator circuits. When voltage is...

In a balanced four-wire wye-to-wye system, the arrangement involves wye-connected sinusoidal voltage sources and loads, connected through a neutral wire that links the neutral nodes of the source and load. The load impedance is connected across each phase of the load. The wye-connected source can be connected to the wye-connected load in four-wire and three-wire arrangements. A three-phase system is considered balanced when the load on each phase is equal, leading to uniform current flow and...

An LC circuit consists of an inductor and a capacitor, either in series or parallel. Consider a charged capacitor connected with an inductor in series. Before the switch is closed, all the energy of the circuit is stored in the electric field of the capacitor. When the switch is closed, the capacitor begins to discharge, producing a current in the circuit. The current, in turn, creates a magnetic field in the inductor. Because of the induced emf in the inductor, the current cannot change...

AC power distribution systems have three categories: single-phase, two-phase, and three-phase systems. The single-phase circuit, common in residential settings, typically employs a two-wire system connecting a single AC source to various loads. These circuits support standard household appliances operating at 120 volts (V) and 240 V, such as lamps, televisions, and microwaves. The first generators, Niagara Falls hydro plant installed in 1895, were two-phase and designed by Nikola Tesla. The...
