HIV Infection and Neurocognitive Disorders in the Context of Chronic Drug Abuse: Evidence for Divergent Findings Dependent upon Prior Drug History
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Neuroimmune Pharmacology"
DOI: 10.1007/s11481-020-09928-5
Abstract: The fronto-striatal circuitry, involving the nucleus accumbens, ventral tegmental area, and prefrontal cortex, mediates goal-directed behavior and is targeted by both drugs of abuse and HIV-1 infection. Acutely, both drugs and HIV-1 provoke increased dopamine… read more here.

DOI: 10.1007/s13365-019-00764-9
Abstract: Neurotoxicity associated with the antiretroviral efavirenz (EFV) has been documented in HIV-infected adults, but there are no data on the impact of EFV on brain function in adolescents. We investigated potential alterations in fronto-striatal function… read more here.

DOI: 10.1016/j.clinph.2018.04.729
Abstract: Carrying conversations in public spaces with a plethora of competing sensory inputs demands flexible interactions between attention and perception for selectively processing goal-relevant information. We postulate that the fronto-striatal network plays a key role in… read more here.

DOI: 10.1016/j.euroneuro.2018.01.002
Abstract: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by structural, functional and neurochemical alterations of the fronto-striatal circuits and by deficits in cognitive control. In particular, ADHD has been associated with impairments in top-down fronto-striatal… read more here.

DOI: 10.1016/j.euroneuro.2018.04.004
Abstract: Tetrahydrocannabinol (THC) and Cannabidiol (CBD) are two substances from cannabis sativa that have beenimplicated in the treatment of mental and neurological disorders. We concentrated on a previously validated neuroimaging phenotype, fronto-striatal connectivity across different striatal… read more here.

DOI: 10.1016/j.schres.2020.09.008
Abstract: BACKGROUND Abnormalities in fronto-striatal-thalamic (FST) sub-circuits are present in schizophrenia and are associated with cognitive impairments. However, it remains unknown whether abnormalities in FST sub-circuits are present before psychosis onset. This may be elucidated by… read more here.

Feature-specific prediction errors and surprise across macaque fronto-striatal circuits
Sign Up to like & getrecommendations! Published in 2019 at "Nature Communications"
DOI: 10.1038/s41467-018-08184-9
Abstract: To adjust expectations efficiently, prediction errors need to be associated with the precise features that gave rise to the unexpected outcome, but this credit assignment may be problematic if stimuli differ on multiple dimensions and… read more here.
