Homeira investigates the impact of intrinsic cellular properties of human cortical neurons on network activity in cortical slices obtained from neurosurgical procedures. Her work focuses on the role of electrophysiological properties of single neurons in generating electrical oscillations in the brain, and using these data to build a human cell model through a collaboration with Dr. Francis Skinner. To perform these experiments, she uses in vivo and in vitro electrophysiology, including patch clamp techniques and local field potential recordings. In addition, she uses 3D image reconstruction of neurons using immunohistochemistry and CLARITY.

Andrea Gómez Palacio
Andrea’s previous research has focused on performing in the large-scale recordings in several animal models to investigate neuronal interactions that underlie plastic states. One of her main interests is to understand how brain stimulation modifies these interactions in order to use it as a rehabilitation tool.
Her current research focuses on performing and analysing single-unit activity in Individuals with medically-intractable epilepsy. Such studies pose a unique opportunity to answer questions related to the neuronal mechanisms involved in human cognitive processing.

Marjan works at the intersection of engineering, neuroscience, and using music to provide a therapeutic option for individuals with Epilepsy. She is interested in reducing the seizure frequency in individuals with epilepsy by listening to music, and improving her understanding on how the brain activity of individuals with epilepsy changes by listening to music. She has been leading the related research line in the lab since 2016 by running different aspects of a clinical research study on this topic including the study design and coordination, participants’ enrolment, data collection, and analyzing the acquired data.
Marjan got her Master of Engineering (MEng) and PhD in Chemical Engineering from University of Birmingham in England. She changed her research field afterwards to the exciting world of neurobiology and neuroscience through an opportunity created by a collaboration between Dr. Frances Skinner and Dr. Taufik Valiante in 2015, which she will be always grateful for. She believes she is a neuroscientist and considers herself fortunate to be able to use her skills and research interests to have a meaningful impact on individuals’ lives.

Azadeh received her Ph.D. in Biomedical Engineering from the University of Montreal and joined the Neuron to Brain lab as a Postdoctoral Research Fellow in March 2018. She has been working on different subjects, including “single-neuron studies of learning, memory, and decision making in human” and “assisting optogenetics experiments using silicon neural nanoprobes”, and is currently exploring the mechanisms of brain neuromodulation by electrical stimulation.
Azadeh is trying to understand how neuromodulation exactly affects the excitability of neuronal networks by stimulating and recording from mice brain slices using Multi-Electrode Arrays (MEAs). She investigates how electrical stimulation affects the excitability of neural tissue, and how these stimulation approaches may be improved towards greater therapeutic benefit.

Scott received his Ph.D in Applied and Interdisciplinary Mathematics from the University of Michigan, and performs his postdoctoral research under the co-supervision of Dr. Valiante and Dr. Frances Skinner. His work aims to use computational tools to mechanistically describe the sometimes paradoxical pathways to seizure. The discovery of such mechanisms has the potential to uncover not only novel experimentally testable hypotheses to improve our understanding of seizure initiation, but also novel targets for clinical intervention to minimize or prevent seizure in patients with epilepsy.
This work takes place at both a micro-scale, where he works to create detailed computational models of human neurons utilizing electrophysiological data from the Neuron to Brain team, and at a macro-scale, in which he investigates how seizure might arise in computational neural networks.

Omid received his PhD in Electrical and Computer Engineering from the University of Toronto. His earlier research aimed at Brain Computer Interface, coordinated activity between motor cortex and basal ganglia in individuals with Parkinson's disease, and modification of neural activity through micro-stimulation of brain structures. His current work aims to uncover neural mechanisms of memory formation and memory recall in primates. The discovery of such mechanisms leads to methods interacting with memory system; with traumatic potentials for individuals suffering from neurological deficiencies such as amnesia, Alzheimer's disease, as well as post-traumatic stress disorder (PTSD).

Kramay works on developing novel neurofeedback protocols to investigate skill learning in mesial temporal lobe structures. This type of skill learning can potentially be used to probe underlying circuitry in the mesial temporal lobe structures (which is largely responsible for memory encoding, and often involved in generating seizures) in a safe and highly precise manner.
