Health, Access to Care, and Financial Barriers to Care Among People Incarcerated in US Prisons.

Importance: Decades-old data indicate that people imprisoned in the US have poor access to health care despite their constitutional right to care. Most prisons impose co-payments for at least some medical visits. No recent national studies have assessed access to care or whether co-pays are associated with worse access.

A synergistic workspace for human consciousness revealed by Integrated Information Decomposition.

How is the information-processing architecture of the human brain organised, and how does its organisation support consciousness? Here, we combine network science and a rigorous information-theoretic notion of synergy to delineate a 'synergistic global workspace', comprising gateway regions that gather synergistic information from specialised modules across the human brain. This information is then integrated within the workspace and widely distributed via broadcaster regions. Through functional MRI analysis, we show that gateway regions of the synergistic workspace correspond to the human brain's default mode network, whereas broadcasters coincide with the executive control network.

Neural markers of reduced arousal and consciousness in mild cognitive impairment.

Objectives: People with Alzheimer's Disease (AD) experience changes in their level and content of consciousness, but there is little research on biomarkers of consciousness in pre-clinical AD and Mild Cognitive Impairment (MCI). This study investigated whether levels of consciousness are decreased in people with MCI.

Methods: A multi-site site magnetoencephalography (MEG) dataset, BIOFIND, comprising 83 people with MCI and 83 age matched controls, was analysed.
