QUANTUM BRAINS. “Motivated by the potential similarities between the underlying mechanisms of the enhanced memory storage capacity in black holes and in brain networks, we construct an artificial quantum neural network based on gravity‐like synaptic connections and a symmetry structure that allows to describe the network in terms of geometry of a d‐dimensional space.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

THE NEURAL QUANTUM. “The neural network can be described in terms of a quantum field, via identifying the different neurons with the different momentum modes of the field, while identifying the synaptic connections among the neurons with the interactions among the corresponding momentum modes.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

SIMPLE ORIGINS. “Given that black holes and human brains exhibit extraordinary memory storage capacities, it is natural to ask whether these systems share some very basic mechanism of the enhanced capacity of the information storage.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

ONE PART OF THE ANSWER. “Obviously, the final answer requires the involvement of biology, which is beyond our expertise. However, we can attempt to do a physicist part of the job.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

RELATED STUDY. “A step in this direction was undertaken, where a general mechanism – originally proposed for the explanation of an enhanced memory capacity in black holes – was applied to the framework of quantum neural networks and was shown that it leads to an exponential enhancement of pattern storage and recognition capacities.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=GdPRXs_tGLEAAAAA%3Ag-pxPMtkcleTYDUNK3mYGfpEzKRyc2LqQknTgFFB7dkYFDL8rDe2s0f4_0Q0oKjXD4_AEgFPGWolVTQ View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on a surprising paper showing that heavy water tastes different from normal water; given the subtlety of the difference, it is surprising and speaks to the exquisitely nuanced nature of taste receptors, that not only can they distinguish the small structural difference but can communicate that to the brain. An extraordinarily thorough paper. View in LinkedIn
