New Variations for Strategy Set-shifting in the Rat09:45

New Variations for Strategy Set-shifting in the Rat

8.6K
Set-shifting, a form of behavioral flexibility, requires an attentional shift from one stimulus dimension to another. We extended an established rodent set-shifting task1 by requiring attention to different stimuli according to context. The task was combined with specific lesions to identify neuron subtypes underlying a successful...

Le Chatelier's Principle: Changing Temperature

35.0K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:

Climate Change

The certainty of climate change remains a public controversy despite the consensus among approximately 97% of active climate researchers, who not only agree that the Earth’s climate is changing but also state that this change is intensified by human activity, predominantly carbon emissions 1. The disconnect between the public and the experts is partly due to poor understanding of the mechanisms involved in climate change as well as the differences among essential concepts such as weather...

Melting Land and Sea Ice
ExpandNOTE: This activity is a simulation of land- and sea-ice melting and their effects on water levels.
First, label one graduated cylinder as 'Sea Ice' and the other graduated cylinder as 'Land Ice.' Hypotheses: the experimental hypothesis might be that the land ice melting will cause the water level to rise more than the melting sea ice. The null hypothesis would be that there will be no difference in the change in water level between the two containers.

Le Chatelier's Principle: Changing Concentration

65.2K
A system at equilibrium is in a state of dynamic balance, with forward and reverse reactions taking place at equal rates. If an equilibrium system is subjected to a change in conditions that affects these reaction rates differently (a stress), then the rates are no longer equal and the system is not at equilibrium. The system will subsequently experience a net reaction in the direction of a greater rate (a shift) that will re-establish the equilibrium. This phenomenon is summarized by Le...

Summary
This summary is machine-generated.

Changing handedness requires significant effort and practice, influencing neural and behavioral patterns. However, a ceiling effect limits the extent of complete handedness shifts.

Area of Science:

  • Neuroscience
  • Human Behavior
  • Cognitive Science

Background:

  • Handedness is a complex human behavior.
  • Modifying handedness involves substantial effort.
  • Understanding handedness shifts can illuminate its developmental processes.

Purpose of the Study:

  • To review and analyze studies on handedness shifts.
  • To explore the relationship between practice and neural/behavioral asymmetries.
  • To identify potential limitations in modifying handedness.

Main Methods:

  • Systematic review of existing literature on handedness modification.
  • Analysis of behavioral measures and brain activation patterns in handedness shift studies.

Main Results:

  • Neural asymmetries correlate with lateralized practice and behavioral changes.
  • Practice plays a significant role in forming and consolidating handedness asymmetries.
  • A ceiling effect was observed, with no studies reporting complete shifts in behavior or brain activity.

Conclusions:

  • Lateralized practice is a key factor in the development of handedness-related neural asymmetries.
  • The capacity to change handedness direction and degree appears to have a limit.
  • Further research is needed to fully understand the plasticity of handedness.
