Cortical networks show characteristic recruitment patterns after somatosensory stimulation by pneumatically evoked repetitive hand movements in newbo…

Abstract Controlled assessment of functional cortical networks is an unmet need in the clinical research of noncooperative subjects, such as infants. We developed an automated, pneumatic stimulation method to actuate naturalistic movements of an infant’s hand, as well as an analysis pipeline for assessing the elicited electroencephalography (EEG) responses and related cortical networks. Twenty newborn infants with perinatal asphyxia were recruited, including 7 with mild-to-moderate hypoxic–ischemic encephalopathy (HIE). Statistically significant corticokinematic coherence (CKC) was observed between repetitive hand movements and EEG in all infants, peaking near the contralateral sensorimotor…
Effect of low dissolved oxygen on the viability of juvenile Margaritifera margaritifera : Hypoxia tolerance ex situ
2022
The decline of endangered freshwater pearl mussel (FPM, Margaritifera margaritifera) has been attributed to juvenile mortality caused by low concentrations of dissolved oxygen in the stream substrate resulting from fine sediments (siltation) that impede water exchange in the interstitial microhabitat of juveniles. If low oxygen concentration causes recruitment failure of FPMs, knowledge on the oxygen tolerance of juvenile FPMs is essential for the conservation of the species, as it will justify conservation efforts improving water exchange in the bottom gravel. However, the tolerance of low oxygen of FPM juveniles has not been directly studied. Juvenile FPMs (9–11 months old) were exposed i…
Neural networks for heart rate time series analysis
2003
Jyväskylän yliopisto, ammattikorkeakoulu ja elinkeinoelämä ovat viimevuosina investoineet voimakkaasti hyvinvointiteknologian kehittämiseen Jyvässeudun alueella. Tavoitteena on ollut kehittää alan yritystoimintaa ja verkostoitumista, sekä koulutusta ja tutkimusta. Tuoreena esimerkkinä on Viveca-talon valmistuminen 2003, jossa hyvinvointiteknologian yritys ja tutkimustoimintaa on integroitu yhteisiin toimitiloihin. Sami Saalastin väitöskirjatyön tutkimustulokset ovat syntyneet pääasiassa kahdessa hyvinvointiteknologiaa edistävässä Tekes -projektissa Kilpa- ja Huippu-urheilun Tutkimuskeskuksessa, sekä Firstbeat Technologies Oy:ssä vuosina 2000-2003. Tutkimusta on ollut rahoittamassa myös Coma…
