Sedentary behavior in children by wearable cameras: development of an annotation protocol

Hänggi, Johanna M. ; Spinnler, Simon ; Christodoulides, Efstathios ; Gramespacher, Elke ; Taube, Wolfgang ; Doherty, Aiden

In: American Journal of Preventive Medicine, 2020, vol. 59, no. 6, p. 880–886

Introduction: There is increasing evidence that not all types of sedentary behavior have the same harmful effects on children's health. Hence, there has been a growing interest in the use of wearable cameras. The aim of this study is to develop a protocol to categorize children's wearable camera data into sedentary behavior components.Methods: Wearable camera data were collected in 3...

Variable interhemispheric asymmetry in layer v of the supplementary motor area following cervical hemisection in adult macaque monkeys

Contestabile, Alessandro ; Colangiulo, R. ; Lucchini, Matteo ; Rouiller, Eric M. ; Schmidlin, Eric

In: eNeuro, 2020, vol. 7, no. 5, p. ENEURO.0280-20.2020

Motor cortical areas from both hemispheres play a role during functional recovery after a unilateral spinal cord injury (SCI). However, little is known about the morphologic and phenotypical differences that a SCI could trigger in corticospinal (CS) neurons of the ipsilesional and contralesional hemisphere. Using an SMI-32 antibody which specifically labeled pyramidal neurons in cortical...

Cortical projection from the premotor or primary motor cortex to the subthalamic nucleus in intact and parkinsonian adult macaque monkeys: a pilot tracing study

Besides the main cortical inputs to the basal ganglia, via the corticostriatal projection, there is another input via the corticosubthalamic projection (CSTP), terminating in the subthalamic nucleus (STN). The present study investigated and compared the CSTPs originating from the premotor cortex (PM) or the primary motor cortex (M1) in two groups of adult macaque monkeys. The first group...
