Neurons are not like transistors; unlike transistors, neurons are influenced by chemicals, neurotransmitters, hormones, and drugs, which change the intensity and inhibition of firing in ways digital computation cannot model.

When you go into a very hot sauna (210°F), the preoptic area communicates with the amygdala to trigger sympathetic nervous system activation (increased heart rate, adrenaline release), creating an impulse to exit the environment, which serves as a protective signal that core body temperature protection is at risk.

Lethargy and the urge to spread out one's limbs on a hot day are controlled by the preoptic area, which modulates skeletal muscle activity and postural behavior to increase surface area for heat dissipation; this explains why physical activity feels difficult in heat and why the body instinctively adopts heat-dumping positions.

Engaging with uncomfortable heat (but safe heat) is necessary to access endorphin and dynorphin pathway benefits for mood elevation, because the dysregulation of dynorphin is central to depression, stress, and addiction, and moderate acute stress through heat exposure upregulates the endorphin system.

Endorphins are released in response to acute stress and bind to the mu opioid receptor, producing pain relief and mild euphoria, while dynorphins (a different class of endorphins) bind to the CAPA receptor and produce agitation, stress, and pain sensations.

For Penrose's quantum consciousness hypothesis to be viable, quantum effects would need to survive in the human brain long enough for a neuron to fire, but the human brain fires extremely slowly, and even basic estimates show this timescale is insufficient for quantum effects to persist.

Stuart Hameroff, a neurobiologist, proposed that microtubules could serve as the specific location where quantum effects sufficient for consciousness arise, suggesting that microtubules can synchronize due to quantum effects, thereby allowing quantum effects to persist long enough to play a role in conscious thought.

Damaging the hippocampus in lab rats lowers the threshold for superstitious conditioning, making it easier to condition false causality beliefs—suggesting a neural substrate for susceptibility to magical thinking and religion.

Damage to the dorsolateral prefrontal cortex (measured in war veterans with head injuries from bullets or shards) is associated with higher rates of mystical experiences and increased reliance on intuition over rational cognition.

If words are not repeated in a child's environment, the opposite neurological process occurs: neurons shrink and die away in a process called 'pruning,' which decreases the ability to learn.

Language drives neurological brain development: each time a word is said, it stimulates a neuron; when that word is repeated, the same neural pathway is stimulated again, strengthening it and creating branching capability for learning.

Nature is still important in the commercial world even though people might assume it is no longer relevant, because the human brain is adaptive and repurposes old brain functions for new applications, such as using naturalist intelligence to discriminate between different clothing styles and haircuts.

We all use naturalist intelligence in modern contexts even if we never walk out into the woods or the savannah, because the brain is adaptive and repurposes cognitive functions for new applications.

The brain allocates disproportionate energy to cellular damage repair relative to other organs, which allows neural tissue to maintain fidelity across a lifespan, and this repair occurs during sleep when neural activity is minimized; however, this strategy cannot be extended to other organs without metabolic collapse.

The human brain has not evolved significantly over the past 100,000-1,000,000 years and retains the same basic neural architecture as hunter-gatherers, yet it shows remarkable adaptability to rapidly changing cultural and technological contexts, raising questions about whether cognitive adaptation can keep pace with technological acceleration.
