The Holistic Mechanics of Brain Function: Understanding ADD, Depression, and Chronic Pain Through Neuronal Activity

This podcast episode, part six of 'User Manual 4 Humans,' emphasizes a holistic view of health, asserting that seemingly disparate conditions like ADD, depression, and chronic pain share common underlying mechanisms within the brain. The core argument is that understanding how the brain's fundamental components—neurons and their connections—function electrically is key to comprehending and improving overall brain health. The discussion begins with brain basics, highlighting that neurons, despite making up only 2% of body mass, consume 20% of the body's energy and blood, underscoring their intense activity in processing electrical signals measured in millivolts.

The episode delves into the development and structure of the brain, noting that while the number of neurons (approximately 100 billion) remains constant from birth to adulthood, the brain's weight increases fourfold due to the proliferation of synapses. These synapses, which are the connections between neurons, form neural networks that represent every skill, habit, and piece of knowledge. The distinction between grey matter (neuron cell bodies) and white matter (myelinated axons for insulation) is explained in the context of efficient electrical circuitry. A crucial point is neuroplasticity: the brain's ability to form new synapses and adapt throughout life, regardless of age, meaning learning and change are always possible.

A significant portion of the episode is dedicated to the 'resting membrane potential' and the 'all-or-nothing' action potential of neurons. It explains how a neuron fires only when its electrical charge reaches a specific threshold (e.g., 60 millivolts), and how this threshold is influenced by thousands of other neurons through either inhibitory (subtracting charge) or facilitative (adding charge) synapses. This complex interplay determines a neuron's responsiveness; a brain cell too close to firing leads to hypersensitivity, while one too far away results in unresponsiveness. The brain's inherent goal is to maintain an ideal level of responsiveness for stability.

Finally, the podcast offers practical insights, stressing that the brain's ability to find and maintain this ideal level of function depends on the continuous use and activation of its neural networks. This is where recommendations like regular exercise and engaging in activities come into play, as they are essential for reinforcing synapses and ensuring the nervous system operates optimally. The broader implication is that a proactive approach to physical and mental activity directly supports the brain's intricate electrical balance, thereby influencing a wide range of conditions from cognitive disorders to chronic pain.

"everything that we talked about really is the same thing but we just use different words and we're approaching it from different directions but there really is just one topic in holism is how does the stuff work and how do we make it work better"

"neurons they make up two percent of your body mass but they use twenty percent of your energy twenty percent of the blood in the body is sent to the brain"

"every skill that you have every habit that you have and everything that you will ever learn or forget is a network of synapses"

"as you learn you make new synapses as you as a skill falls out of favor as you stop doing something you just simply stop reinforcing those synapses and if you don't use them you lose them"

"your brain can change regardless of your age and it does this at any age"

"once you get to 60 hypothetically speaking I just take that number then everything breaks loose all at once it's an all-or-nothing response"

"the activity of a brain cell the perception of a brain cell is determined by other brain cells"

"if a brain cell is really really close to firing then just about anything is going to send it off and those are people who are hypersensitive to things"

"the functioning nervous system font works to automatically find the ideal level but in order for this to happen we need to use the brain cells and we need to keep these networks active"

"that's where chiropractic and exercise and activation of the system comes in that's why I keep nagging about exercise and about doing things"
