The ability to assess executive functions such as behavioral flexibility in rats is useful for investigating the neurobiology of cognition in both intact animals and disease models. Here we describe automated tasks for assessing strategy shifting and reversal learning, which are particularly sensitive to disruptions in prefrontal cortical networks.

Segmentation of three-dimensional data from many imaging techniques is a major bottleneck in analysis of complex biological systems. Here, we describe the use of SuRVoS Workbench to semi-automatically segment volumetric data at various length-scales using example datasets from cryo-electron tomography, cryo soft X-ray tomography, and phase contrast X-ray tomography techniques.

FAQs
Hydrogen bonding and hydrophobic packing provide the stabilizing interactions that preserve local organization, while flexibility permits limited conformational change. This balance prevents movement from becoming structural failure. Its importance is practical: a segment can adjust during binding or folding while the surrounding molecule retains enough integrity to support biological activity.
A sequence change can modify the interactions that stabilize a segment or change how readily it moves. Because these regions respond to their molecular environment, altered flexibility may affect folding, binding, or signaling. Examining sequence variation therefore helps connect molecular changes with shifts in biological activity rather than treating structure as completely rigid.
Movement within these segments can adjust the shape of an active site, influencing how a molecule recognizes or accommodates a binding partner. They may also connect more rigid domains and transmit conformational effects between regions. In allostery, this provides a structural basis for linking an interaction at one location with functional changes elsewhere.
Binding partners and environmental conditions can shift the balance between stabilizing interactions and local movement. Such changes may favor a different conformation, altering the way regions meet or interact. Researchers use this relationship to interpret why the same molecule can show different folding, recognition, or signaling behavior under different molecular circumstances.
These segments provide a way to relate molecular dynamics to several biological processes, including protein folding, molecular recognition, binding, and signaling. Their behavior can reveal how structural adjustments support function while preserving overall organization. Studying them is especially useful when activity depends on communication between domains or on changes near an active site.
Researchers examine how the segments respond to sequence, environmental, and binding-partner changes, then relate those responses to functional outcomes. This approach helps explain why a molecule may retain its overall structure yet change its activity. In biology, the resulting structural-function analysis supports interpretation of recognition, allostery, folding, and signaling mechanisms.
