Midbrain-hypothalamic interrelationships in the control of aggressive behavior

Previous studies have suggested an involvement of the midbrain ventral tegmental area in the biting attack upon a rat elicited by electrical stimulation of the lateral hypothalamus in cats. In order assess further the relationship between these two regions, 12 cats were implanted with attack-eliciting electrodes in both the lateral hypothalamus and the midbrain ventral tegmental area. Following a lesion of the midbrain attack site, attack previously elicited from hypothalamic electrodes ipsilateral to the lesion was eliminated or significantly reduced in frequency. The attack elicited from electrodes in the hypothalamus contralateral to the lesion was unaffected. Midbrain lesions made at sites from which attack was never elicited had no effect on hypothalamically elicited attack. The midbrain lesion in some cases eliminated only certain components of the total attack pattern; for example, the approach of a cat to the rat frequently remained present while the bite was absent. Additionally, it was found that the attack elicited from rostral hypothalamic electrodes was disrupted to a greater degree by a single midbrain lesion than the attack elicited from more caudal hypothalamic electrodes. These finding are discussed in terms of the neural system mediating this form of aggressive behavior in cats.

Development and Implementation of a Transdiagnostic,Stepped-Care Approach to Treating Emotional Disorders in Children via Telehealth

Stepped-care interventions may increase the accessibility of evidence-based treatments but remain relatively underexplored in the child mental health literature. Further, while the feasibility and efficacy of stepped-care interventions have been examined for specific diagnoses or classes or disorders, transdiagnostic stepped-care interventions have not yet been developed. We discuss the development and initial implementation of a transdiagnostic approach to emotional disorders using the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children (UP-C; Ehrenreich-May et al., 2018). A case series is presented to illustrate the delivery of UP-C stepped care (UPC-SC) via telehealth, using a collaborative decision-making process to inform step-up/step-down decisions. Lessons learned are discussed to guide refinements of UPC-SC and inform a larger trial.
