Disentangling the Neural Circuits of Arousal and Anxiety-Like Behavior.
Curr Top Behav Neurosci
November 2024
Article Synopsis
- Anxiety disorders are widespread and severely impact individuals, causing excessive worry and fear that alters thoughts and behaviors.
- Arousal, which involves regulating alertness and paying attention to stimuli, plays a key role in anxiety but can become poorly regulated, leading to either hypoarousal (low alertness) or hyperarousal (high alertness), which affects how threats are perceived.
- The chapter highlights difficulties in researching arousal in anxiety models and suggests that new methods combining physiological measurements with detailed neuron activity tracking are essential for advancing treatment options.
A wide selection of behavioral assays in systems neuroscience relies on head-fixation protocols to integrate in vivo multi-photon imaging approaches. For this, simultaneous pupillometry and locomotion tracking in head-fixed mice are used to measure behavioral responses and identify neural correlates. Here, we present an open-source protocol for assembling a complete head-fixation system that integrates pupillometry and locomotion-estimated tracking with multi-photon calcium imaging.

- Traumatic social experiences impact behavior by enhancing survival and safety, but how the brain's networks regulate these changes is not well understood.* -
- Researchers combined traditional and modern techniques to track mouse behaviors during social threat learning, discovering new movements that reveal alterations in social motivation.* -
- Analysis of brain activity showed significant changes in several key regions when mice recognized a social threat, indicating that altered brain connectivity is important for modifying behavior in response to such threats.*
Aims And Method: Workplace violence and aggression toward healthcare staff has a significant impact on the individual, causing self-blame, isolation and burnout. Timely and appropriate support can mitigate harm, but there is little research into how this should be delivered. We conducted multi-speciality peer groups for London doctors in postgraduate training (DPT), held over a 6-week period.
