Scientists have discovered new insights into how our brain stores episodic memories—a type of long-term, conscious memory of a previous experience—that could be critical to the development of new neuroprosthetic devices to help patients with memory problems, like Alzheimer’s disease and dementia.

The new study—led by the University of Glasgow, in collaboration with the University of Birmingham and University of Erlangen—used special electrodes, implanted directly into the brains of epilepsy patients requiring surgery, to allow scientists to observe the activity of individual neurons in the hippocampus region of the brain.

The hippocampus is a challenging area to study, due to its location deep within the brain, yet this area is critical for our memory, acting as the librarian to the memory library in our brain.

A recent study reports something strange: When mice with Alzheimer’s disease inhale menthol, their cognitive abilities improve. It seems the chemical compound can stop some of the damage done to the brain that’s usually associated with the disease.

In particular, researchers noticed a reduction in the interleukin-1-beta (IL-1β) protein, which helps to regulate the body’s inflammatory response – a response that can offer natural protection but one that leads to harm when it’s not controlled properly.

The team behind the study, which was published in April 2023, says it shows the potential for particular smells to be used as therapies for Alzheimer’s. If we can figure out which odors cause which brain and immune system responses, we can harness them to improve health.

It wouldn’t shock me if all the buzz around searching for the ‘locus of consciousness’ merely fine-tunes our grasp of how the brain is linked to consciousness — without actually revealing where consciousness comes from, because it’s not generated in the brain. Similarly, your smartphone doesn’t create the Internet or a cellular network; it just processes them. Networks of minds are a common occurrence throughout the natural world. What sets humans apart is the impending advent of cybernetic connectivity explosion that could soon evolve into a form of synthetic telepathy, eventually leading to the rise of a unified, global consciousness — what could be termed the Syntellect Emergence.

In summary, the study of consciousness could be conceptualized through a variety of lenses: as a series of digital perceptual snapshots, as a cybernetic system with its feedback processes, as a grand theater; or perhaps even as a VIP section in a cosmological establishment of magnificent complexity. Today’s leading theories of consciousness are largely complementary, not mutually exclusive. These multiple perspectives not only contribute to philosophical discourse but also herald the dawn of new exploratory avenues, equally enthralling and challenging, in our understanding of consciousness.

In The Cybernetic Theory of Mind (2022), I expand on existing theories to propose certain conceptual models and concepts, such as Noocentrism, Digital Presentism (D-Theory of Time), Experiential Realism, Ontological Holism, Multi-Ego Pantheistic Solipsism, the Omega Singularity, deeming a non-local consciousness, or Universal Mind, as the substrate of objective reality. In search of God’s equation, we finally look upward for the source. What many religions call “God” is clearly an interdimensional being within the nested levels of complexity. Besides setting initial conditions for our universe, God speaks to us in the language of religion, spirituality, synchronicities and transcendental experiences.

Summary: Neuroscientists delved into the mechanisms behind true and false memories. Their study reveals that electrical signals in the hippocampus can differentiate between the imminent recall of authentic versus fabricated memories.

By monitoring neural activity in epilepsy patients, the team identified distinct patterns ahead of a correct or false recall. These findings not only offer insights into memory retrieval but may also pave the way for novel therapeutic interventions for disorders like PTSD.
