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.

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Environmental enrichment involves objects and practices that encourage natural behaviors, improve psychological well-being, and promote better welfare in laboratory rodents. Environmental enrichment should be tailored to the...
FAQs
Threat appraisal can activate the sympathetic nervous system, contributing to heightened arousal, while subsequent hypothalamic-pituitary-adrenal axis signaling influences stress-related regulation. Together, these processes can affect emotional regulation, attention, and memory. This framework helps psychologists connect threatening surroundings with changes in functioning without assuming that every exposed person will develop the same symptoms.
Repeated or prolonged exposure may sustain stress-related activation and increase the likelihood of difficulties involving arousal, emotional regulation, attention, memory, trust, or daily functioning. However, responses vary across individuals and contexts. The psychological outcome therefore depends not only on exposure itself but also on how the experience is interpreted and situated within a person’s broader circumstances.
People can respond differently because environmental trauma unfolds within different personal and social contexts. One person may experience post-traumatic stress symptoms, while another may show anxiety, depression, difficulties with trust, or changes in daily functioning. These variations make it important to avoid assuming a uniform psychological response and to consider each person’s circumstances during evaluation.
Culturally responsive assessment considers how threatening or disruptive experiences affect people within their social and cultural contexts. It can help distinguish patterns involving post-traumatic stress symptoms, anxiety, depression, trust, and daily functioning while avoiding assumptions that one response fits everyone. This approach supports a more accurate understanding of needs and can guide appropriate prevention or intervention planning.
Environmental trauma is relevant whenever disasters, violence, displacement, or chronic environmental stressors affect psychological safety and functioning. Prevention planning can address risks before or after exposure, while community recovery efforts can focus on restoring safety, coping, and social support. These approaches recognize that recovery involves both individual well-being and the conditions surrounding affected communities.
Interventions can aim to strengthen safety, coping, and social support while addressing difficulties in arousal, emotional regulation, attention, memory, trust, or daily functioning. Their purpose is not to presume one outcome for every person, because responses vary across individuals and contexts. Psychological assessment can help connect intervention planning with the specific effects and needs that emerge.
