Research has shown that when individuals are in situations that do not occasion one form of motoric responding, they will engage in another so that the overall level of motoric responding is homeostatic. The purpose of this study was to test whether students would substitute task-related behaviors for stereotypic or other challenging behaviors when the opportunity for active responding did or did not match the level of motoric responding in a free-operant baseline. Four students with mental retardation participated. Results showed that they did substitute behaviors, with stereotypic and other challenging behaviors occurring 1.5-14 times as much in the Non-matched condition for the four students. Further analysis showed considerably more of these behaviors in passive than in active tasks (by a factor up to 21 times as much). Results were discussed in terms of homeostasis, functional assessment, and opportunities to improve educational behaviors.

The cerebellum, identified to be active during cognitive and social behavior, has multisynaptic connections through the cerebellar nuclei (CN) and thalamus to cortical regions, yet formation and modulation of these pathways are not fully understood. Perineuronal nets (PNNs) respond to changes in local cellular activity and emerge during development. PNNs are implicated in learning and neurodevelopmental disorders, but their role in the CN during development is unknown.

We investigated whether Mayo Test Drive (MTD), a self-administered multi-device compatible cognitive assessment platform, demonstrates usability and correlation with traditional neuropsychological tests in a pilot study of individuals with progressive supranuclear palsy (PSP).
Method: Eleven individuals with PSP (mean age = 69.

Background: Frontotemporal degeneration (FTD) is a complex, heterogeneous group of fatal adult-onset disorders which lead to progressive dysfunction in behavior, motor symptoms, language, and/or cognition. While advances in research are cause for optimism, trials are hindered by the availability of participants. As FTD clinical trials typically require co-participation of a study partner, care partner perspectives on research are critical to understanding how to support recruitment and retention.

Objective: Epilepsy is common among patients with severe motor and intellectual disability (SMID) patients, often taking a prolonged and intractable course. Lacosamide (LCM) is widely used to treat epilepsy in both adults and children. We assess the efficacy and tolerability of LCM among pediatric and young adult epilepsy patients with SMID who suffer from intractable seizures.

Background: Evidence from multiple converging sources has demonstrated the clear benefits of physical activity in promoting mental health and improving cognitive function. However, more than 54% of Indians do not engage in the recommended amount of physical activity. The present study aims to explore the association of physical activity with cognitive abilities among the elderly aging population in an urban Indian setting.
