Tom Mrsic-Flogel is an experimental neuroscientist. He is Director of the Sainsbury Wellcome Centre and a Professor in Neuroscience at University College London (UCL). [1] Mrsic-Flogel is a founding member of the International Brain Laboratory. [2]

Contents

Mrsic-Flogel’s research focuses on establishing mechanistic accounts of brain function, including how brain areas communicate and contribute to perception, cognition and learning. [3] [4] [5] His research has potential implications for psychiatric disorders such as autism and schizophrenia [6] and future applications in brain-computer interfaces (BCIs). [7] [8]

Education and career

Mrsic-Flogel received his undergraduate degree and PhD in 2001 from Oxford University. He completed postdoctoral work with Tobias Bonhoeffer at the Max Planck Institute of Neurobiology (since 2023 named Max Planck Institute for Biological Intelligence) in Munich. In 2007, he became Lecturer and Wellcome Trust Fellow at UCL, after which he was appointed as Professor at the University of Basel. [9]

Since 2016, Mrsic-Flogel has been Director of the Sainsbury Wellcome Centre for Neural Circuits and Behaviour, an independently-funded neuroscience institute (Gatsby Charitable Foundation and Wellcome) opened in 2014 and hosted by UCL. [10]

Research and work

Mrsic-Flogel is known for detailing the wiring principles of the brain’s networks and how these relate to their function. [11] His work has used new approaches to measure individual synaptic connections between brain cells of known function, and molecular anatomy tools, to show the extent of influence of individual neurons on the rest of the brain. [12]

Through his research in the visual cortex, Mrsic-Flogel discovered that synaptic connections are not organized randomly but are structured according to several specific wiring principles:

Mrsic-Flogel has demonstrated how the wiring of neural circuits is adjusted through experience and learning. [20] His work has shown how circuits are optimally tuned to the statistical regularities of the natural world [21] and how learning can further refine neural circuits in the adult brain. [22]

Mrsic-Flogel’s current lab studies how the brain makes decisions by combining sensory information with previously learned knowledge. [23] Research from the Mrsic-Flogel lab has revealed how visual working memory in mice is maintained across interconnected brain regions. [24]

Scientists in the Mrsic-Flogel lab have shed light on how the brain represents causally-controlled objects. [25] [26] More recently, the Mrsic-Flogel lab investigated how individual neurons in mice are influenced by two different cognitive and behavioural states – attention and running – that were once thought to share a common mechanism. They found that spatial attention and running influence neurons independently with different dynamics. [27] [28]

The development of the nervous system, or neural development (neurodevelopment), refers to the processes that generate, shape, and reshape the nervous system of animals, from the earliest stages of embryonic development to adulthood. The field of neural development draws on both neuroscience and developmental biology to describe and provide insight into the cellular and molecular mechanisms by which complex nervous systems develop, from nematodes and fruit flies to mammals.

Computational neuroscience is a branch of neuroscience which employs mathematics, computer science, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system.

<span class="mw-page-title-main">Neocortex</span> Mammalian structure involved in higher-order brain functions

The neocortex, also called the neopallium, isocortex, or the six-layered cortex, is a set of layers of the mammalian cerebral cortex involved in higher-order brain functions such as sensory perception, cognition, generation of motor commands, spatial reasoning and language. The neocortex is further subdivided into the true isocortex and the proisocortex.

<span class="mw-page-title-main">Claustrum</span> Structure in the brain

The claustrum is a thin sheet of neurons and supporting glial cells, that connects to the cerebral cortex and subcortical regions including the amygdala, hippocampus and thalamus of the brain. It is located between the insular cortex laterally and the putamen medially, encased by the extreme and external capsules respectively. Blood to the claustrum is supplied by the middle cerebral artery. It is considered to be the most densely connected structure in the brain, and thus hypothesized to allow for the integration of various cortical inputs such as vision, sound and touch, into one experience. Other hypotheses suggest that the claustrum plays a role in salience processing, to direct attention towards the most behaviorally relevant stimuli amongst the background noise. The claustrum is difficult to study given the limited number of individuals with claustral lesions and the poor resolution of neuroimaging.
