Repeated toluene inhalation in male and female adolescent rats induces persistent drug preference and impairs cognitive and social behavior.

Rationale: Adolescent inhalant use is an understudied and undertreated disorder, particularly in females. Chronic exposure to inhalants, like toluene, can have long-lasting effects on behavior. However, most animal studies lack the incorporation of both sexes and do not focus on the abstinence period.

Mentoring to propagate racial inclusivity in neuroscience.

Mentoring the next generation of neuroscientists from historically excluded backgrounds brings several challenges. Successful mentor-mentee relationships are critical for addressing these challenges. Rodriguez-Romaguera and Quirk reflect on lessons learned from their cross-racial mentor-mentee relationship that could apply to many mentors.

Specific Patterns of Endogenous Functional Connectivity Are Associated With Harm Avoidance in Obsessive-Compulsive Disorder.

Background: Individuals with obsessive-compulsive disorder (OCD) show persistent avoidance behaviors, often in the absence of actual threat. Quality-of-life costs and heterogeneity support the need for novel brain-behavior intervention targets. Informed by mechanistic and anatomical studies of persistent avoidance in rodents and nonhuman primates, our goal was to test whether connections within a hypothesized persistent avoidance-related network predicted OCD-related harm avoidance (HA), a trait measure of persistent avoidance.

Determinants of B cell responses to drifted epitopes in post-vaccination SARS-CoV-2 infections.

Vaccine-induced immunity may impact subsequent responses to drifted epitopes in SARS-CoV-2 variants, but this has been difficult to quantify due to the challenges in recruiting unvaccinated control groups whose first exposure to SARS-CoV-2 is a primary infection. Through local, statewide, and national SARS-CoV-2 testing programs, we were able to recruit cohorts of individuals who had recovered from either primary or post-vaccination infections by either the Delta or Omicron BA.1 variants.
