The dynamic adrenal response of children to cardiac surgery and cardiac catheterization

Daniel Fudulu, Isabella Marinelli, Daniel Galvis, Eder Zavala et autres

CONTEXT: The hypothalamic-pituitary-adrenal (HPA) axis is the key homeostatic system regulating the response to surgical stress. Imbalances in HPA axis hormones increase morbidity and mortality in children after cardiac surgery. Despite this, the physiology of the HPA axis in children undergoing cardiac …

Phase synchronisation in coupled oscillator chains with endpoint heterogeneity

Daniel Galvis, Kyle C. A. Wedgwood

The emergence of collective dynamics within heterogeneous networks is a key feature of many biological networks. Heterogeneity of excitability, for example, has become a focus in the study of how pancreatic islets coordinate insulin secretion. This has raised the question of how …

The impact of paediatric epilepsy and co-occurring neurodevelopmental disorders on functional brain networks in wake and sleep

Leandro Junges, Daniel Galvis, Alice Winsor, Grace Treadwell et autres

Epilepsy is one of the most common neurological disorders in children. Diagnosing epilepsy in children can be very challenging, especially as it often coexists with neurodevelopmental conditions like autism and ADHD. Functional brain networks obtained from neuroimaging and electrophysiological data in wakefulness …

Using compartmental models to understand excitation-inhibition imbalance in epilepsy

Aravind Kumar, Matthew Parker Szuromi, Daniel Galvis, William C. Stacey et autres

Epileptic seizures are characterized by abnormal synchronous bursting of neurons. This is commonly attributed to an imbalance between excitatory and inhibitory neurotransmission. We introduce compartmental models from epidemiology to study this interaction between excitatory and inhibitory populations of neurons in the context …

Modelling the dynamic interaction of systemic inflammation and the hypothalamic–pituitary–adrenal (HPA) axis during and after cardiac surgery

Daniel Galvis, Eder Zavala, Jamie J. Walker, Thomas Upton et autres

Major surgery and critical illness produce a potentially life-threatening systemic inflammatory response. The hypothalamic-pituitary-adrenal (HPA) axis is one of the key physiological systems that counterbalances this systemic inflammation through changes in adrenocorticotrophic hormone (ACTH) and cortisol. These hormones normally exhibit highly correlated …

Virtual intracranial EEG signals reconstructed from MEG with potential for epilepsy surgery

Miao Cao, Daniel Galvis, Simon J. Vogrin, William P. Woods et autres

Modelling the interactions that arise from neural dynamics in seizure genesis is challenging but important in the effort to improve the success of epilepsy surgery. Dynamical network models developed from physiological evidence offer insights into rapidly evolving brain networks in the epileptic …

The dynamic interaction of systemic inflammation and the hypothalamic-pituitary-adrenal (HPA) axis during and after major surgery

Daniel Galvis, Eder Zavala, Jamie J. Walker, Thomas Upton et autres

Major surgery and critical illness produce a potentially life threatening systemic inflammatory response. The hypothalamic-pituitary-adrenal (HPA) axis is one of the key physiological systems that counterbalances this systemic inflammation through changes in adrenocorticotrophic hormone (ACTH) and cortisol. These hormones normally exhibit highly …

A dynamical systems model for the measurement of cellular senescence

Daniel Galvis, Darren Walsh, Lorna W. Harries, Eva Latorre et autres

Senescent cells provide a good in vitro model to study ageing. However, cultures of ‘senescent’ cells consist of a mix of cell subtypes (proliferative, senescent, growth-arrested and apoptotic). Determining the proportion of senescent cells is crucial for studying ageing and developing new …

Interhemispheric dominance switching in a neural network model for birdsong

Daniel Galvis, Wei Wu, Richard L. Hyson, Frank Johnson et autres

Male zebra finches produce a sequence-invariant set of syllables, separated by short inspiratory gaps. These songs are learned from an adult tutor and maintained throughout life, making them a tractable model system for learned, sequentially ordered behaviors, particularly speech production. Moreover, much …
