Our Lab focuses on understanding the brain's self-repair capacity after injury, and developing novel therapeutic approaches based on electrical stimulation of neural tissue. We adopt a bottom up approach, starting from single cell optical manipulation, passing through the investigation of in vitro neuronal circuits, up to the study of novel stimulation protocols to be applied within in vivo cortico-cortical networks with the aim at promoting recovery after brain injury.
For this purpose I’ve been involved in an EC-funded project Brain Bow (http://www.brainbowproject.eu), focused on the development of technological tools for brain repair. Here I characterized the spontaneous and evoked activity of 2D finite-size networks grown on Multi Electrode Arrays (MEAs), before and after selective laser dissection of physical connections between neuronal sub-populations. This quantitative characterization of the lesion-induced changes in activity will allow for a reproducible injury model to possibly test innovative ‘brain-prostheses‘.
Due to the collaboration with the laboratory of Randolph Nudo at the University of Kansas Medical Center (KU Med), I moved from in vivo neural networks to in vivo animal models. In this framework our strategy is to use electrical stimulation of a neural tissue as a tool to guide the plasticity of the network following an injury. We are comparing different kinds of protocols in both open and closed-loop (in particular, activity dependent stimulation) in order to investigate whether or not the electrical stimulation can be used to potentiate functional connectivity between distant cortical locations in both healthy and injured (Stroke or Traumatic brain injury TBI) rat brains.
In 2012, Alberto Averna graduated in Biomedical Engineering at the University of Pavia(ITALY), with a thesis about Data mining techniques for the differentiation stage prediction of stem cells (IPSCs) from DNA microarrays data.
In July 2014, he was awarded a Master Degree in Bioengineering (Neuroengineering curriculum). Thesis: Study of modular neural network’s dynamics in both physiological and pathological condition.
In November 2014, he started the PhD in Neuroscience at Istituto Italiano di Tecnologia (Neuroscience and Brain Technologies Department).
From January to May 2015, he was trained in In Vivo ICMS and models of brain injuries at University of Kansas Medical Center (Ku Med)
