Aging Modulates the Resting Brain after a Memory Task: A Validation Study from Multivariate Models
Artola, Garazi; Isusquiza Garcia, Erik; Errarte, Ane; Barrenechea, Maitane; Alberdi Aramendi, Ane (MDPI AG, 2019)Recent work has demonstrated that aging modulates the resting brain. However, the study of these modulations after cognitive practice, resulting from a memory task, has been scarce. This work aims at examining age-related ... -
Association of retinal neurodegeneration with the progression of cognitive decline in Parkinson’s disease
Romero-Bascones, David; Ayala, Unai; Barrenechea, Maitane (Springer Nature, 2024)Retinal thickness may serve as a biomarker in Parkinson’s disease (PD). In this prospective longitudinal study, we aimed to determine if PD patients present accelerated thinning rate in the parafoveal ganglion cell-inner ... -
Foveal Pit Morphology Characterization: A Quantitative Analysis of the Key Methodological Steps
Romero-Bascones, David; Barrenechea, Maitane; Ayala, Unai (MDPI, 2021)Disentangling the cellular anatomy that gives rise to human visual perception is one of the main challenges of ophthalmology. Of particular interest is the foveal pit, a concave depression located at the center of the ... -
Foveal Remodeling of Retinal Microvasculature in Parkinson’s Disease
Barrenechea, Maitane; Erramuzpe Aliaga, Asier; Ayala, Unai; Romero-Bascones, David (Frontiers, 2021)Background: Retinal microvascular alterations have been previously described in Parkinson’s disease (PD) patients using optical coherence tomography angiography (OCT-A). However, an extensive description of retinal vascular ... -
Fully pipelined implementation of tree-search algorithms for vector precoding
Barrenechea, Maitane; Mendicute, Mikel; Arruti, Egoitz (Hindawi, 2013)The nonlinear vector precoding (VP) technique has been proven to achieve close-to-capacity performance in multiuser multipleinput multiple-output (MIMO) downlink channels. The performance benefit with respect to its linear ... -
Retinal Optical Coherence Tomography Features Associated With Incident and Prevalent Parkinson Disease
Romero-Bascones, David; Ayala, Unai; Barrenechea, Maitane (American Journal of Analogy, 2023)Background and Objectives Cadaveric studies have shown disease-related neurodegeneration and other morphological abnormalities in the retina of individuals with Parkinson disease (PD); however, it remains unclear whether ... -
Retinal thickness predicts the risk of cognitive decline in Parkinson's disease
Ayala, Unai; Barrenechea, Maitane (Wiley, 2021)Objective: To analyze longitudinal changes of retinal thickness and their predictive value as biomarkers of disease progression in idiopathic Parkinson’s disease (iPD). Methods: Patients with Lewy body diseases (LBDs) ... -
Spatial characterization of the effect of age and sex on macular layer thicknesses and foveal pit morphology
Romero-Bascones, David; Ayala, Unai; Alberdi Aramendi, Ane; Erramuzpe Aliaga, Asier; Barrenechea, Maitane (PLoS, 2022)Characterizing the effect of age and sex on macular retinal layer thicknesses and foveal pit morphology is crucial to differentiating between natural and disease-related changes. We applied advanced image analysis techniques ...
