  10. Retinal atrophy in relation to visual functioning and vision-related quality of life in patients with multiple sclerosis.

    Balk, LJ; Coric, D; Nij Bijvank, JA; Killestein, J; Uitdehaag, BM; Petzold, A
    BACKGROUND: Inner retinal layer atrophy in patients with multiple sclerosis (MS) has been validated as a structural imaging biomarker for neurodegeneration. OBJECTIVE: To determine how retinal layer thickness relates to high-contrast visual acuity (HCVA), low-contrast visual acuity (LCVA) and vision-related quality of life (QoL) and to investigate the effect of previous episodes on MS-associated optic neuritis (MSON). METHODS: Spectral-domain optical coherence tomography (SD-OCT) was performed in 267 patients with MS. Images were segmented for the peripapillary retinal nerve fiber layer (pRNFL) and the macular ganglion cell inner plexiform layer (GCIPL). Ophthalmological evaluations included history of MSON, HCVA, LCVA, and vision-related...

  13. Bayesian Belief Updating of Spatiotemporal Seizure Dynamics

    Cooray, GK; Rosch, R; Baldeweg, T; Lemieux, L; Friston, K; Sengupta, B
    Epileptic seizure activity shows complicated dynamics in both space and time. To understand the evolution and propagation of seizures spatially extended sets of data need to be analysed. This requires efficient methods of inference. We have previously described an efficient filtering scheme using variational Laplace that can be used in the Dynamic Causal Modelling (DCM) framework to estimate the temporal dynamics of seizures recorded using either invasive or non-invasive electrical recordings (EEG/ECoG). In this note, we present a method to analyse the spatiotemporal dynamics of seizures. Spatiotemporal dynamics are modelled using a partial differential equation - in contrast to the...

  14. Sentient Self-Organization: Minimal dynamics and circular causality

    Sengupta, B; Friston, K
    Theoretical arguments and empirical evidence in neuroscience suggests that organisms represent or model their environment by minimizing a variational free-energy bound on the surprise associated with sensory signals from the environment. In this paper, we study phase transitions in coupled dissipative dynamical systems (complex Ginzburg-Landau equations) under a variety of coupling conditions to model the exchange of a system (agent) with its environment. We show that arbitrary coupling between sensory signals and the internal state of a system -- or those between its action and external (environmental) states -- do not guarantee synchronous dynamics between external and internal states: the...

  15. The variational principles of action

    Friston, K
    © 2017, Springer International Publishing AG.This chapter provides a theoretical perspective on action and the control of movement from the point of view of the free-energy principle. This variational principle offers an explanation for neuronal activity and ensuing behavior that is formulated in terms of dynamical systems and attracting sets. We will see that the free-energy principle emerges when considering the ensemble dynamics of biological systems like ourselves. When we look closely what this principle implies for the behavior of systems like the brain, one finds a fairly straightforward explanation for many aspects of action and perception; in particular, their...

  17. The touched self: Affective touch and body awareness in health and disease

    Gentsch, A; Crucianelli, L; Jenkinson, P; Fotopoulou, A
    © 2016 Springer Science+Business Media New York.This chapter focuses on how interpersonal, affective touch shapes our sense of self as embodied beings. In the first section, we highlight the centrality of bodily representations for our psychological sense of self, with special emphasis on the role of internal bodily signals in forming the emotional, core of selfhood. The second section focuses on affective touch as a domain of interoception and addresses its important contribution to healthy body representation and bodily awareness. Specifically, we present recent, accumulating evidence in healthy volunteers pointing to the crucial role of affective touch in the construction...

  20. Sexual dysfunction following rectal cancer surgery.

    Celentano, V; Cohen, R; Warusavitarne, J; Faiz, O; Chand, M
    INTRODUCTION: Sexual and urological problems after surgery for rectal cancer are common, multifactorial, inadequately discussed, and untreated. The urogenital function is dependent on dual autonomic sympathetic and parasympathetic innervation, and four key danger zones exist that are at risk for nerve damage during colorectal surgery: one of these sites is in the abdomen and three are in the pelvis. The aim of this study is to systematically review the epidemiology of sexual dysfunction following rectal cancer surgery, to describe the anatomical basis of autonomic nerve-preserving techniques, and to explore the scientific evidence available to support the laparoscopic or robotic approach...
