These findings are from a study in @PhysRevE which employs cavity quantum electrodynamics to explore entangled biphoton generation through cascade emission as a potential source for the synchronized activity of neurons. 2/13 journals.aps.org/pre/abstract/1…
Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others. 3/13
The idea that the human brain contains quantum properties was first suggested in the 90s by physicist @penrose and anesthesiologist @StuartHameroff with their “orchestrated objective reduction” model of a consciousness. 4/13
The synchronization of neurons within the cerebral cortex serves as the foundation for diverse neurobiological processes, closely linked to anomalies in brain function and brain diseases. 5/13
Recent studies have highlighted the role of the photon as a quantum object whereby ultraweak photon emission in living organisms is now implicated in neuronal function. 6/13
Photons released during tricarboxylic acid cycle in neurons resonantly couple to C-H bond vibrons in lipid molecules, altering possibly the dielectric constant of the membrane to enhance action potential conduction. 7/13
The myelin sheath, a lipid membrane encasing the outer side of a neuron's axon, provides energy to the axon, enhances action potential conduction, and acts as an insulator in the nervous system. 8/13
The myelin sheath is generally regarded only as an insulator; however, emerging evidence suggests myelin's plasticity, indicating its role beyond insulation and its potential to promote neural phase synchronization. 9/13
This study demonstrates that the vibrational spectrum of C-H bonds in lipid molecule's tails, within the myelin sheath encasement, can generate quantum entangled photon pairs through cascade radiation from the second excited state to the ground state. 10/13
This indicates that the cylindrical cavity formed by a myelin sheath can facilitate spontaneous photon emission from the vibrational modes and generate a significant number of entangled photon pairs. 11/13
The abundance of C-H bond vibration units in neurons can therefore serve as a source of quantum entanglement resources for the nervous system. 12/13
Overall, these findings may offer insight into the brain's ability to leverage these resources for quantum information transfer, thereby elucidating a potential source for the synchronized activity of neurons. 13/13

These findings are from a paper in @scisignal which describes how sleep deprivation increases resting energy expenditure, leading to the development of a negative energy balance in highly active cells like neurons. 2/8 science.org/doi/10.1126/sc…

A history of heavy cannabis use is associated with lower brain activation during a working memory task.

These findings are from a study in @JAMANetworkOpen which examined the association of lifetime history of heavy cannabis use and recent cannabis use with brain activation across a range of brain functions in a large sample of young adults in the US. 2/9 jamanetwork.com/journals/jaman…
Given the cognitive effects of cannabis and the disruption of the endogenous cannabinoid system by tetrahydrocannabinol (THC), it may be that brain regions with high cannabinoid 1 (CB1) receptor density might be altered by cannabis. 3/9
These findings are from a paper in @JAMAPsych which described how the paternal brain is wired by pregnancy. 2/12 jamanetwork.com/journals/jamap…
Pregnancy and post partum are accompanied by structural (extensive gray matter volume reductions) and functional brain changes in women that are thought to be important for caregiving. 3/12

Recently, INTEGRATE, the international guidelines for the algorithmic treatment of schizophrenia were released, and we commend the authors for their focus on “metabolic health from treatment initiation”. 2/11 thelancet.com/journals/lanps…
However, in line with The Lancet Psychiatry Commission for Protecting the Physical Health in People with Mental Illness, such treatment guidelines are incomplete without simultaneous discussion of lifestyle interventions. 3/11 thelancet.com/journals/lanps…
These findings are from a paper in @APAPubJournals which discussed the importance of refining our diagnostic nosology of depression through the lens of inflammation. 2/10 psychiatryonline.org/doi/10.1176/ap…
Chronic inflammation plays a prominent role in multiple medical disorders, including psychiatric diseases such as major depression. 3/10
Coffee enhances neurocognitive function by reorganizing brain functional connectivity.

These findings are from a study in @SciReports which investigated functional connectivity before and after drinking coffee using graph-theoretic analysis of electroencephalography (EEG). 2/8 nature.com/articles/s4159…
Integration of neural activities between different brain regions is required for physiological brain functioning; therefore, analyzing functional connectivity between brain regions may provide more information than investigating activities of individual brain regions. 3/8
