Generation of slow BOLD signals from coupled neural mass models in the gamma range.
Èlia presented a poster that delved into the generation of slow Blood Oxygen Level Dependent (BOLD) signals and their relationship with neural mass models (NMMs) in the gamma frequency range. This investigation was exemplified using a basic model consisting of two coupled NMMs oscillating in the gamma band and further extended to a more complex whole-brain model with a realistic connectome. By studying these models, valuable insights were gained into the origins of slow BOLD signals and their interplay with neural mass dynamics.
LSD-induced increase of Ising temperature and algorithmic complexity of brain dynamics.
Giada presented a poster about the analysis of fMRI data taken under LSD ingestion and placebo. Using the Ising model and algorithmic complexity, our study aimed to characterize the two brain states with measurable features.
Regular and sparse neuronal synchronization are described by identical mean field dynamics (poster)
Connectivity Profiles: How information flow, across and within hemispheres, differs in various brain states
Steady-state changes induced by external electric fields in different neocortical neuron types (presentation)
Adrià extended the content of the previous year's poster with a talk about the theoretical framework developed to model the steady-state changes induced by external electric fields based on spherical harmonics, and the different experiments in-silico that grounded the work - which was published later on here.
