The identification of complex spatiotemporal patterns using Coupled map lattice model [PDF]

open access: yes, 2006
Many complex and interesting spatiotemporal patterns have been observed in a wide range of scienti¯c areas. In this paper, two kinds of spatiotemporal patterns including spot replication and Turing systems are investigated and new identi¯cation methods ...

Spatiotemporal analysis of renal autoregulation

open access: yesThe FASEB Journal, 2011
Laser speckle perfusion imaging was used to study vascular interactions among nephrons in relation to renal autoregulation on physiologically relevant spatial and temporal scales. Surface images of stabilized rat kidneys were collected with a moorFLPI imager (Moor Instruments, UK) at a sampling rate of 1 Hz. High resolution time‐frequency spectra (TFS)

Lessons Learned From a Delayed‐Start Trial of Modafinil for Freezing of Gait in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Freezing of gait (FOG) in people with Parkinson's disease (PwPD) is debilitating and has limited treatments. Modafinil modulates beta/gamma band activity in the pedunculopontine nucleus (PPN), like PPN deep brain stimulation. We therefore tested the hypothesis that Modafinil would improve FOG in PwPD.

Dynamic Decomposition of Spatiotemporal Neural Signals

open access: yes, 2016
Neural signals are characterized by rich temporal and spatiotemporal dynamics that reflect the organization of cortical networks. Theoretical research has shown how neural networks can operate at different dynamic ranges that correspond to specific types

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.
