Blood flow response to orthostatic challenge identifies signatures of the failure of static cerebral autoregulation in patients with cerebrovascular disease

Publikováno v: BMC Neurology, Vol 21, Iss 1, Pp 1-12 (2021)

Abstract Background The cortical microvascular cerebral blood flow response (CBF) to different changes in head-of-bed (HOB) position has been shown to be altered in acute ischemic stroke (AIS) by diffuse correlation spectroscopy (DCS) technique. Howe

Functional Near-Infrared Spectroscopy to Study Cerebral Hemodynamics in Older Adults During Cognitive and Motor Tasks: A Review

Autor: Cristina Udina, Stella Avtzi, Turgut Durduran, Roee Holtzer, Andrea L. Rosso, Carmina Castellano-Tejedor, Laura-Monica Perez, Luis Soto-Bagaria, Marco Inzitari

Publikováno v: Frontiers in Aging Neuroscience, Vol 11 (2020)

The integrity of the frontal areas of the brain, specifically the prefrontal cortex, are critical to preserve cognition and mobility in late life. Prefrontal cortex regions are involved in executive functions and gait control and have been related to

PREFRONTAL BLOOD FLOW DURING DUAL-TASK WALKING IN ADULTS WITH AND WITHOUT MILD COGNITIVE IMPAIRMENT

Autor: Cristina Udina Argilaga, Stella Avtzi, Turgut Durduran, Andrea Rosso, Miriam Mota, Joan Ars, Marco Inzitari

Publikováno v: Innovation in Aging. 6:608-608

Background Blood flow differences in the prefrontal cortex (PFC) during dual-task walking are thought to indicate various degrees of neural efficiency. Individuals with poorer neural resources might need higher activation to meet behavioral performan

Functional diffuse correlation spectroscopy measurements on cognitively healthy and mild cognitive impaired populations during single and dual motor tasks

Autor: Luis Soto-Bagaria, Miriam Mota, Carmina Castellano-Tejedor, Marco Inzitari, Stella Avtzi, Veronika Parfentyeva, Turgut Durduran, Cristina Udina

Publikováno v: Optical Tomography and Spectroscopy of Tissue XIV.

Functional diffuse correlation spectroscopy was used during various attention-demanding motor tasks, and test whether cerebral blood flow (CBF) changes differentiate between age groups or are related to mild cognitive impairment (MCI). Sixty-nine sub

Hidden projection tomography via phase retrieval algorithm

Autor: Asier Marcos Vidal, Andrea Bassi, Diego Di Battista, Daniele Ancora, Giannis Zacharakis, Stella Avtzi

The reconstruction of an object hidden behind a scattering curtain is a modern topic in the field of imaging, which has stimulated an active scientific production over the past few years. However, most of the work done in the field was in addressing

Hidden phase-retrieved fluorescence tomography

Autor: Andrea Bassi, Stella Avtzi, Daniele Ancora, Asier Marcos Vidal, Giannis Zacharakis, Diego Di Battista

Publikováno v: Optics Letters

Fluorescence tomography is a well-established methodology able to provide structural and functional information on the measured object. At optical wavelengths, the unpredictable scattering of light is often considered a problem to overcome, rather th

Phase Retrieval for Hidden Tomography Reconstruction

Autor: Asier Marcos Vidal, Stella Avtzi, Diego Di Battista, Giannis Zacharakis, Daniele Ancora, Andrea Bassi

We discuss the problem of tomographic reconstruction of fluorescent objects hidden behind random media. To accomplish this, we focus on the properties of the autocorrelation, relying on phase retrieval algorithms to perform 3D reconstruction.
