Our brains are made up of tiny nerve cells called “neurons” which branch out and connect to each other forming a neural network. At each connection point, thoughts and emotions are incubated and holographically stored by associative memory. This means that all ideas, thoughts, feelings, and memories are interconnected and have possible relationships with one another. For instance the concept of motherhood is stored in all our neural networks, but each person’s concept is built from their own unique amalgamation of ideas, emotions and past experiences. Some people may have motherhood connected to unconditional love and forgiveness, so when they think about motherhood, they experience memories/feelings of happiness and acceptance. Other people may have motherhood connected to disappointment and ridicule, so when they think about motherhood, they experience memories/feelings of rejection and depression. We all build our own neural networks based on our own subjective experiences, how we perceive and what we believe...

Neuroimaging study suggests a single dose of ayahuasca produces lasting changes in two important brain networks
By Eric W. Dolan August 3, 2020

Consuming a single dose of the psychedelic brew ayahuasca can result in lasting changes in higher-order cognitive brain networks, according to a new study published in the Journal of Psychopharmacology.

Ayahuasca, a concoction used for centuries by indigenous Amazon tribes, contains the powerful psychedelic drug dimethyltryptamine (DMT) and monoamine oxidase inhibitors. The brew is typically prepared using leaves from the Psychotria viridis shrub and the bark of the Banisteriopsis caapi vine.

The new neuroimaging research suggests that ayahuasca may produce long-lasting effects on mood by altering the functional connectivity of the brain’s salience and default mode networks.

“As a clinical neuroscientist, I am interested in approaches that can improve the life of patients with neuropsychiatric disorders,” said study author Lorenzo Pasquini, a postdoctoral fellow at the Memory and Aging Center at the University of California, San Francisco.

“Psychedelic substances were almost completely banned from academic research for the last 70 years. The revival of psychedelic research of the last years provides an exciting opportunity to study the clinical potential of psychedelic therapy sessions on mood disorders affecting millions of persons worldwide.”

“As a computational neuroscientist, I am particularly interested in the role that specific neural circuits play in social-emotional behavior. Psychedelic substances, and the associated altered state of consciousness elicited by their serotonergic action, provide us with a novel way to study how these neural systems support human emotions and social behavior.”

In the study, the researchers used functional magnetic resonance imaging to analyze the brain structure of about 50 healthy participants one day before and one day after they received either a single low dose of ayahuasca or a placebo substance. None of the participants had prior experience with the psychedelic drug.

“While most studies so far have explored the neuronal correlates of altered states of consciousness during the acute phase of a psychedelic session, our study focuses on the subacute effects by assessing changes in brain functional organization one day after the session,” Pasquini explained.

Pasquini and his colleagues found that “the psychedelic experience induced by ayahuasca has a long-lasting effect on the functional organization of brain networks supporting higher order cognitive and affective functions,” he said.

The researchers observed increased anterior cingulate cortex connectivity within the salience network, decreased posterior cingulate cortex connectivity within the default mode network, and increased connectivity between the salience and default mode networks in the ayahuasca group compared to the placebo group.

“We found that ayahuasca had an impact on two important brain networks that support interoceptive (processing of bodily sensations, like from the guts and other internal organs), affective, and motivational functions, while primary sensory networks (visual, sensorimotor) were not affected one day after the session,” Pasquini told PsyPost.

“Consistently, functional changes in these networks related to altered levels of affect, interoception, and motivation assessed during the acute session, providing a link between long-lasting brain changes and altered states of consciousness elicited by ayahuasca. Importantly, these findings may provide a conceptual framework to further explore the therapeutic potential of psychedelic substances in mood and affective disorders.”

All research includes some limitations, and the current study is no exception. “The major caveats for this study relate to the moderate sample size and scanner field strength used, which did affect our statistical power. The field would greatly profit from replication studies with larger samples using state-of-the-art facilities,” Pasquini said.

The researchers also would like to learn more about how psychedelic therapy impacts the functional brain organization of clinical populations, such as those with major depression.

“The field is just beginning to understand the impact that psychedelic substances and the associated altered state of consciousness have on brain function and affect, not only during the acute sesion but also in the long-term,” Pasquini added.

“Importantly, the pharmacological properties of these substances cannot be dissociated from the setting where the experience takes place. In other words, the right dosage, the right guidance, and a safe environment are all factors that critically impact the therapeutic potential of entheogens.”

The study, “Subacute effects of the psychedelic ayahuasca on the salience and default mode networks“, was authored by Lorenzo Pasquini, Fernanda Palhano-Fontes and Draulio B Araujo.

Senses beyond the five...

While daily-daily we make use of the five senses, those beyond normal perception aren't studied or used.

Here are several beyond the standard five:
nociception — the ability to sense pain
thermoception — the ability to sense changes in temperature
proprioception — the ability to sense where your joints and body parts are in relation to other parts of your body
equilibrioception — a sense of balance
- a sense of time

What time is it? They reset the clock when Jesus arrived, right? How old is the universe?

I was told "ganja" was made illegal because it enhances the sixth sense though it also has the effect of making one difficult to (mind) control. Pre-cognition, or an ability to see through and or transcend time.

Interesting too as yoga teaches balance and possibly joint awareness.

Have you, yourself, ever tried to reach out beyond the 'normal' senses?

My goal was to try and fix this place, to end war, stop violence, bring peace to the world. As of yet none of my efforts have been successful as you may have noticed.

Lately I've been reluctantly embracing stoicism...this too shall pass. If they should slap your left cheek, offer them the right as well...
All out of cheeks lately.

Peace y'all from a very depressed and aching soul. Help bring love into the world. Please.

Don't despair. We're all just trying to figure out the real nature of reality and why we are here. I have felt from a very young age that I'm here to witness and experience the end of this cycle. Of course, as a child I was thinking through the lens of a protestant religion, so it was quite scary but I was prepared to be brave. As an adult, I feel I'm here to observe and take away knowledge that will be injected into the next cycle that will help prevent what has happened in this one. Really, we must bring back integrity and respect for truth. When that happens, peace will follow organically. That's my biggest takeaway from being on this planet. :hug1:
Don't believe anything they say.
And at the same time,
Don't believe that they say anything without a reason.

Fine thoughts and wishes, Pele'sDaughter.

Find the peace you seek, thrulookingglass. It's inside you, itching to come out and encompass you with your love.

To paraphrase a Buddha saying (re seeking love), it is not a matter of seeking peace, it's a matter of removing all the obstacles within you that prevent it from being.

...the influence of the Self isn’t limited to internal psychological phenomena. Nor, as it turns out, are the influences of the other archetypes. They also seem to be able to bring about strings of meaningful coincidences, in which the outer world suddenly mirrors the inner world...

That landed Jung in deep waters indeed. In the Western world from 1650 on, two dogmas have provided the foundations of modern thought. The first can be called the dogma of materialism: the insistense that everything that exists in the universe is ultimately nothing more than matter in motion. The second can be called the dogma of mechanism: the insistence that everything that happens in the universe is the result of precise and, at least in theory, predictable chains of cause and effect. Combine these two—and in practice, they are always applied together—and you get a vision of the universe in which everything that happens must by definition be brought about by some material cause. Consciousness? From within that standpoint, it’s an illusion generated by lumps of matter behaving in complex but ultimately mechanical ways. Meaning, purpose, and value? From within that standpoint, these are phantoms belonging to that same illusion.

He does make a start on understanding the basics of self understanding imho...
