Claims

Musicians develop improved auditory memory, enabling better conversation comprehension in difficult listening situations.

Playing a musical instrument will improve chances of understanding friends and family in social situations despite age-related hearing decline.

A musician's husband notices specific sound qualities that define motorcycle types (not just identifying that it is a motorcycle) due to refined auditory perception from musical training.

The most dopaminergically reinforcing moment is not the achievement or possession of what you wanted, but the surprise that something is better than expected; the anticipation of a positive event provides more dopamine than the event itself.

Change blindness exists not only in visual perception but also with respect to experience over time; people do not notice how different each moment's experience is from the next, which contributes to the illusion of being a solid, unchanging entity.

Most illusions humans experience are evolutionary glitches rather than adaptations that emerged for their usefulness.

Memory plays a crucial role in creating the experience of self by stringing together disparate moments into a coherent narrative; without this memory-based continuity, the sense of a self moving through time would be substantially reduced.

Neural structures associated with fear and fight-flight are activated when humans neurologically imagine change, suggesting that humans are neurologically built to resist change and make boldness difficult.

No IQ gland exists in the brain because there is nowhere that eliminates fluid intelligence when damaged; fluid intelligence emerges from the brain's learning of individual specialized problems and their recombination rather than from a dedicated neural substrate.

Brain evolution needs to achieve behavioral success, so without brain mechanisms one cannot understand psychological functions including learning, but without psychological functions the brain mechanisms have no behavioral meaning—therefore understanding any psychological process requires simultaneous analysis of both brain mechanisms and behavioral function in real time.

Opponent processes realized through gated dipole circuits solve multiple dilemmas including arousal regulation: two opponent channels compete and are gated by transmitters (medium-term memories) that habittuate; when a fearful stimulus triggers the on-channel and then shuts off, habituation means the off-channel rebounds, creating relief—the balance between arousal, habituation, and rebound explains emotional dynamics and disorders.

When sedentary, the brain interprets this as a signal of safety, suggesting that nothing important is happening and it is time to rest, rather than enter learning mode.

The brain's reward center, mediated by dopamine, is fundamental to motivation and decision-making; without functioning reward systems, organisms lack reasons to engage in activities, and the absence of reward motivation can lead to severe depression and suicidal ideation.

Dopamine is responsible for motivation, attention, and the feeling of satisfaction from accomplishment; when dopamine function is impaired, individuals struggle to complete tasks because insufficient reward satisfaction makes activity seem unjustified.

The brain operates as a prediction and updating machine: it stores predictions about what will happen, receives new information from the world, compares predictions to actual outcomes, and updates its internal models—all processes that have intrinsic directionality in time.
