Coarse-graining and criticality in the human connectome

1 code implementation29 Sep 2023 Youssef Kora, Christoph Simon

This, in principle, allows for the drawing of similar qualitative conclusions by analysing the smaller networks, which opens the door for studying the human connectome in contexts typically regarded as computationally intractable, such Integrated Information Theory and quantum models of the human brain.

Global excitability and network structure in the human brain

1 code implementation3 Jan 2023 Youssef Kora, Salma Salhi, Jörn Davidsen, Christoph Simon

We utilize a model of Wilson-Cowan oscillators to investigate structure-function relationships in the human brain by means of simulations of the spontaneous dynamics of brain networks generated through human connectome data.

Network analysis of the human structural connectome including the brainstem

1 code implementation22 Jul 2022 Salma Salhi, Youssef Kora, Gisu Ham, Hadi Zadeh Haghighi, Christoph Simon

The underlying anatomical structure is fundamental to the study of brain networks, but the role of brainstem from a structural perspective is not very well understood.

Photons guided by axons may enable backpropagation-based learning in the brain

1 code implementation21 Mar 2022 Parisa Zarkeshian, Taylor Kergan, Roohollah Ghobadi, Wilten Nicola, Christoph Simon

Here we suggest that biophotons guided by axons provide a potential channel for backward transmission of information in the brain.

Radical pairs may explain reactive oxygen species-mediated effects of hypomagnetic field on neurogenesis

no code implementations25 Oct 2021 Rishabh, Hadi Zadeh-Haghighi, Dennis Salahub, Christoph Simon

This study proposes a radical pair mechanism based on a flavin-superoxide radical pair to explain the modulation of ROS production and the attenuation of adult hippocampal neurogenesis in a hypomagnetic field.

Hippocampus

Radical pairs may play a role in microtubule reorganization

no code implementations28 Sep 2021 Hadi Zadeh-Haghighi, Christoph Simon

Based on a simple radical pair mechanism model and a simple mathematical model of MT organization, we show that magnetic fields can modulate spin dynamics of naturally occurring radical pairs in MT.

Open-Ended Question Answering

Can quantum physics help solve the hard problem of consciousness? A hypothesis based on entangled spins and photons

no code implementations8 Sep 2018 Christoph Simon

Moreover the concept of matter is much more subtle in quantum physics compared to classical physics, and quantum computing shows that quantum effects can be useful for information processing.

Towards a global quantum network

no code implementations31 Oct 2017 Christoph Simon

The creation of a global quantum network is within reach combining satellite links and quantum memory based approaches.

Are there optical communication channels in the brain?

no code implementations23 Aug 2017 Parisa Zarkeshian, Sourabh Kumar, Jack Tuszynski, Paul Barclay, Christoph Simon

Despite great progress in neuroscience, there are still fundamental unanswered questions about the brain, including the origin of subjective experience and consciousness.

Quantum repeaters based on atomic ensembles and linear optics

no code implementations15 Jun 2009 Nicolas Sangouard, Christoph Simon, Hugues de Riedmatten, Nicolas Gisin

Such protocols require the capacity to create entanglement in a heralded fashion, to store it in quantum memories, and to swap it.
