Radical pair model for magnetic field effects on NMDA receptor activity [PDF]
Scientific Reports, 2023 The N-methyl-D-aspartate receptor is a prominent player in brain development and functioning. Perturbations to its functioning through external stimuli like magnetic fields can potentially affect the brain in numerous ways.

Radical-pair model of magnetoreception with spin–orbit coupling [PDF]
New Journal of Physics, 2013 The mechanism used by migratory birds to orientate themselves using the geomagnetic field is still a mystery in many species. The radical pair mechanism, in which very weak magnetic fields can influence certain types of spin-dependent chemical reactions,

Reaction field-dependent spin-correlated radical pair model: A new insight into liposomal drug-delivery system [PDF]
AIP Advances, 2020 This work was focused on new drug-release potentials associated with phospholipid-bilayer structures and magnetic field effects, as it were, a liposomal nanoparticle model with reaction field-dependent spin-correlated radical pair mechanisms. The release

Sensing Magnetic Directions in Birds: Radical Pair Processes Involving Cryptochrome [PDF]
Biosensors, 2014 Birds can use the geomagnetic field for compass orientation. Behavioral experiments, mostly with migrating passerines, revealed three characteristics of the avian magnetic compass: (1) it works spontaneously only in a narrow functional window around the ...

A New Type of Radical-Pair-Based Model for Magnetoreception [PDF]
Biophysical Journal, 2012 Certain migratory birds can sense the Earth's magnetic field. The nature of this process is not yet properly understood. Here we offer a simple explanation according to which birds literally see the local magnetic field through the impact of a physical rather than a chemical signature of the radical pair: a transient, long-lived electric dipole moment.

Radical pairs may play a role in microtubule reorganization
Scientific Reports, 2022 The exact mechanism behind general anesthesia remains an open question in neuroscience. It has been proposed that anesthetics selectively prevent consciousness and memory via acting on microtubules (MTs).

The Innovation, 2022 How animals sense the geomagnetic field remains a mystery today. A remarkable diversity has been revealed in animal magnetoreception and several sophisticated models have been put forward in the past few decades, but none have been commonly accepted yet.

The Magnetic Compass of Birds: The Role of Cryptochrome
Frontiers in Physiology, 2021 The geomagnetic field provides directional information for birds. The avian magnetic compass is an inclination compass that uses not the polarity of the magnetic field but the axial course of the field lines and their inclination in space.

Radical triads, not pairs, may explain effects of hypomagnetic fields on neurogenesis.
PLoS Computational Biology, 2022 Adult hippocampal neurogenesis and hippocampus-dependent cognition in mice have been found to be adversely affected by hypomagnetic field exposure. The effect concurred with a reduction of reactive oxygen species in the absence of the geomagnetic field ...
