Dear All,
The CEU Department of Cognitive Science and the Center for Cognitive Computation (CCC)

Forum<https://ccc.ceu.edu/budapest-computational-neuroscience-forum>um>. Please note
that there will be two talks consecutively.
Speakers: Morten L Kringelbach<https://www.psych.ox.ac.uk/team/mlk> (University of
Oxford) and Gustavo
Deco<https://www.upf.edu/web/cns/gustavo> (Pompeu Fabra
University)
Titles and abstracts:
Whole-brain modelling. Cartography of eudaimonia and flourishing in the human brain
In order to survive, the brain must constantly extract, predict and recognise the
essential
spacetime features of complex environments. This distributed computation of information
relies on having a hierarchy of optimal information transfer across the whole brain at the
lowest possible metabolic cost. Suboptimal brain orchestration has been linked to mental
illness, yet the fundamental principles of brain orchestration over fast and slow
timescales are
still not well understood. I will show how significant progress has been made using whole-
brain modelling of neuroimaging data using new frameworks based on stochastic
thermodynamics and turbulence. A series of studies have already furthered our
understanding
of human flourishing using data from experiments including music, food, social
interactions,
meditation and psychedelics. Overall, this new evidence has given rise to a deeper
understanding of experiences that can give rise to both flourishing and suffering,
providing
meaning and purpose to life, and may eventually help to find novel ways to rebalance the
brain in neuropsychiatric disorders.
The computing brain: Explaining cognition through a realistic whole-brain anatomically
constrained-reservoir model
The perhaps most important unsolved problem in neuroscience is how the brain survives in a
complex world by performing a rich repertoire of computation on a minimal energy budget.
The brain is much better at adapting to the multiplicity of stimuli and outcomes than
current
generations of computers, artificial neural deep learning and reservoir model
architectures.
Yet, at first glance the brain appears to use a fixed anatomical architecture to perform
the
necessary huge variety of computations. But evolution’s boldest trick is that in fact
the brain’s effective connectivity is constantly being updated through neuromodulation to
allow the rich repertoire of computation. Inspired by this, we created a whole-brain model
using empirical neurotransmitter maps modulating the underlying local regional dynamics.
This NEMO (neurotransmission modulated) whole-brain model is able to flexibly compute
the full task repertoire and associated functional connectivity of the neuroimaging data
from
971 healthy participants. For each individual we defined a measure of ‘brain
computability’
as the fitting of the NEMO whole-brain model to all tasks performed by the individual.
Importantly, brain computability correlates with both behavioural performance on
individual
tasks and with a general behavioural measure of intelligence. Overall, our proposed
unifying
NEMO framework offers a natural way to sculpt different brain dynamics in a fixed brain
architecture to compute the rich repertoire of tasks required for surviving and thriving.
