In the basal ganglia circuitry, the striatum is a highly complex structure coordinating motor and cognitive functions and it is severely affected in Huntington's disease (HD) patients. Transplantation of fetal ganglionic eminence (GE) derived precursor cells aims to restore neural circuitry in the degenerated striatum of HD patients. Pre-clinical transplantation in genetic and lesion HD animal models has increased our knowledge of graft vs. host interactions, and clinical studies have been shown to successfully reduce motor and cognitive effects caused by the disease. Investigating the molecular mechanisms of striatal neurogenesis is a key research target, since novel strategies aim on generating striatal neurons by differentiating embryonic stem cells or by reprogramming somatic cells as alternative cell source for neural transplantation.

Exposure to ionizing radiation during manned deep space missions to Mars could lead to functional impairments of the central nervous system, which may compromise the success of the mission and affect the quality of life for returning astronauts. Along with radiation-induced changes in cognitive abilities and emotional status, the effects of increased motor activity were observed. The mechanisms behind these phenomena still remain unresolved.

Neurodegenerative disorders are characterized by a progressive loss of neurons, causing substantial deficits in motor and cognitive functioning. Bilirubin is a yellow by-product of heme, existing in two primary isoforms namely unconjugated and conjugated, while initially produced unconjugated isomer is lipophilic and cytotoxic in nature. At physiological levels, bilirubin has an important role in brain function by acting as a powerful antioxidant, preventing brain tissues from oxidative damage by eliminating reactive oxygen species (ROS).

Objective: To investigate the effects of intrauterine and perinatal exposure to chikungunya virus (CHIKV) on neurodevelopment in infants and toddlers.
Study Design: We conducted a cohort study comparing children with intrauterine or perinatal exposure to maternal CHIKV infection with unexposed controls in Rio de Janeiro, Brazil. Neurodevelopment was assessed with General Movement Assessments (GMA) in the first six months of life, and the Bayley-III Scales of Infant and Toddler Development and Modified Checklist for Autism in Toddlers (M-CHAT) for older children.

The benefits of estrogen treatment on cognition in middle-aged and older women are dependent on many factors, including the timing of treatment. Moreover, the potential interactive effects with other lifestyle factors, such as exercise, are poorly understood. In this study, we tested for lasting benefits of independent and combined treatment with estrogen and voluntary exercise initiated in midlife, using a rat model of menopause.

Whisker deprivation at different stages of early development results in varied behavioral outcomes. However, there is a notable lack of systematic studies evaluating the specific effects of whisker deprivation from postnatal day 0 (P0) to P14 on adolescent behavioral performance in mice. To investigate these effects, C57BL/6J mice underwent whisker deprivation from P0 to P14 and were subsequently assessed at 5 weeks of age using a battery of tests: motor skills were evaluated using open field test; emotional behavior was evaluated using a series of anxiety- and depression-related behavioral tests; cognitive function was examined via novel location and object recognition tests; and social interactions were analyzed using three-chamber social interaction test.
