Summary
Past experiences change behavior through molecular mechanisms. Ca(2+)/calmodulin-dependent kinase I (CaMKI) was found to regulate thermal preferences based on prior experiences.
Area of Science:
- Neuroscience
- Molecular Biology
- Behavioral Science
Background:
- Understanding how past experiences modify behavior is crucial.
- Experience-dependent plasticity underlies adaptive responses.
- Molecular mechanisms of behavioral plasticity remain largely unknown.
Purpose of the Study:
- To investigate the molecular basis of experience-dependent plasticity in thermosensory behavior.
- To identify key molecules regulating thermal preference shifts due to experience.
Main Methods:
- Dissection of molecular pathways involved in thermosensory behavior.
- Analysis of gene and protein function in experience-dependent plasticity.
Main Results:
- Ca(2+)/calmodulin-dependent kinase I (CaMKI) plays a critical role.
- CaMKI activity is essential for regulating thermal preferences based on past experiences.
Conclusions:
- CaMKI is a key molecular regulator of behavioral adaptation to thermal experiences.
- These findings provide insights into the neural and molecular underpinnings of memory-guided behavior.

Thermal Stress
3.7K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

Mechanisms of Heat Transfer II
5.6K
In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

C4 Pathway and CAM
50.9K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Mechanisms of Heat Transfer I
7.7K
Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.

Quantifying Heat
66.7K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher...

M-Cdk Drives Transition Into Mitosis
6.8K
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
