This work studies upper-limb impairment resulting from stroke or traumatic brain injury and presents a simple technological solution for a subset of patients: a soft, active stretching aid for at-home use. To better understand the issues associated with existing associated rehabilitation devices, customer discovery conversations were conducted with 153 people in the healthcare ecosystem (60 patients, 30 caregivers, and 63 medical providers). These patients fell into two populations: spastic (stiff, clenched hands) and flaccid (limp hands).

Any written work concerning the history of neuroanatomy would be difficult to imagine without acknowledging the pioneering works of Santiago Ramón y Cajal and Camillo Golgi. Cajal improved upon Golgi's staining technique at the turn of the 20th century. He implemented it to deliver the world's first incredibly detailed visualizations of cellular networks of the nervous system.

Although numerous definitions of brain death exist, the diagnosis and diagnostic process remain open to interpretation. We present the case of a 32-year-old male with systemic lupus erythematosus who presented to an outside hospital following a cardiac arrest while jogging. His electroencephalogram (EEG) showed abnormal contour in the posterior fields.

Background And Objectives: Loneliness is linked to significant health threats and is potentially more dangerous than obesity; it affects as many as 29% of noninstitutionalized older adults. Loneliness is exacerbated for those who require inpatient rehabilitation, are displaced from their social networks, spend little time receiving therapy, and are physically inactive and socially isolated. Emerging evidence suggests that companion animals provide a number of health and well-being benefits and that interacting with a trained therapy dog may reduce loneliness.

Increasing evidence suggests that interlocutors use visual communicative signals to form predictions about unfolding utterances, but there is little data on the predictive potential of facial signals in conversation. In an online experiment with virtual agents, we examine whether facial signals produced by an addressee may allow speakers to anticipate the response to a question before it is given. Participants (n = 80) viewed videos of short conversation fragments between two virtual humans.
