Spatial Cueing

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

Pseudofracture, a reproducible murine model of sterile musculoskeletal trauma, allows for evaluation of late term post-traumatic immune responses. This article describes the procedural execution of the model step by step, including the potential for experimental model combinations to permit study of multiple trauma.

We present a protocol of personalized script-driven trauma-related imagery and clinical assessments within a comparison design for investigating peritraumatic dissociation (PD), psychophysiological reactions, i.e. heart rate (HR) and skin conductance (SC), and psychological features of often severely traumatized individuals with borderline personality disorder (BPD).

Acute brain trauma is a severe injury that has no adequate treatment to date. Multiphoton microscopy allows studying longitudinally the process of acute brain trauma development and probing therapeutical strategies in rodents. Two models of acute brain trauma studied with in vivo two-photon imaging of brain are demonstrated in this protocol.

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.
FAQs
During Trauma-related Cues Exposure, reminders can activate conditioned fear and threat networks, producing measurable emotional, physiological, and neural responses. If the cue is presented repeatedly in a controlled setting without the traumatic outcome, reactivity may decline. This pattern is understood as extinction supported by new inhibitory learning, which changes how the cue is processed without implying that the original memory has been erased.
Extinction is important because it adds new learning that inhibits a previously conditioned threat response when the cue is encountered without the traumatic outcome. The approach therefore examines regulation of fear-related responding rather than assuming the original traumatic memory disappears. This distinction helps neuroscience researchers interpret reduced reactivity as altered control over responses, not necessarily loss of the underlying memory.
These measures provide complementary views of the response. Autonomic activity reflects physiological reactivity, behavioral observations show how an individual responds, and brain imaging provides information about neural activity associated with the cues. Examining them together helps researchers evaluate emotional and threat-related processing, compare response patterns, and identify factors that may influence recovery or treatment effectiveness.
A study typically identifies reminders associated with the traumatic event, presents them under controlled conditions, and records emotional, physiological, behavioral, or neural responses. Repeated presentations may occur without the traumatic outcome so researchers can examine extinction and inhibitory learning. The resulting measurements allow investigators to track changes in reactivity and relate them to memory and stress-regulation processes.
In neuroscience research, the method can examine how traumatic memories relate to emotional responses, stress regulation, and threat processing. It also provides a framework for studying mechanisms underlying post-traumatic stress disorder. Combining cue presentations with response measures helps researchers connect observable reactivity with memory-related and neural processes, supporting investigation of why responses vary across individuals.
Clinicians adapt related exposure procedures to support symptom reduction, whereas research protocols use the approach to characterize responses and mechanisms. Its clinical relevance comes from examining whether repeated, controlled cue presentation changes emotional or physiological reactivity. Behavioral, autonomic, and brain-imaging measures can help evaluate treatment effectiveness and identify factors associated with recovery.
