Why you can 'hear' words inside your head

A surprising discovery in the sound emission decoding experiment

The experiment for the not-so-novel study of sound emission decoding involved sixteen patients to read linguistic expressions aloud.

The most remarkable information taken during the experiment was that when the patients read the linguistic expressions without emitting a single noise, the signal that entered the brain was not a sound wave but instead a light signal which conserved the architecture as that of a mechanical sound wave corresponding to words that had actually been uttered.

About Consciousness

Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.

Many modern analytic philosophers of mind either d...

Searching For Physical Footprints

What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.

Consider this question: What must happen in your brain for you to experience a toothache?

Neuronal Correlates of Consciousness (NCC)

The whole brain can be considered an NCC because it generates experience continually.

  • When parts of the cerebellum, the "little brain" underneath the back of the brain, are lost to a stroke or otherwise, patients may lose the ability to play the piano, for example.  But they never lose any aspect of their consciousness. This is because the cerebellum is almost wholly a feed-forward circuit. There are no complex feedback loops.
  • The spinal cord and the cerebellum are not enough to create consciousness. Available evidence suggests neocortical tissue in generating feelings.
  • The next stages of processing are the broad set of cortical regions, collectively known as the posterior hot zone, that gives rise to conscious perception. In clinical sources of causal evidence, stimulating the posterior hot zone can trigger a diversity of distinct sensations and feelings.
  • It appears that almost all conscious experiences have their origin in the posterior cortex. But it does not explain the crucial difference between the posterior regions and much of the prefrontal cortex, which does not directly contribute to subjective content.
Near-death experiences (NDEs)
Near-death experiences (NDEs)

NDEs are triggered during a life-threatening situation when the body is injured by blunt trauma, e.g., a heart attack or shock.

Many survivors tell of leaving their damaged...

Negative NDEs experiences

Not all NDEs are positive - some can be frightening, with intense terror, anguish, loneliness, and despair. Distressing NDEs are underreported because of shame, social stigma, and pressure to conform to the positive NDEs.

A close encounter with death reminds us of the fragility of life and can reveal the layers of psychological suppression that prevents us from these uncomfortable thoughts.

The NDE phenomenon

A 2017 study found that NDEs were recalled with greater clarity and detail than either real or imagined situations were. In other words, NDEs were remembered as being more real than life itself.

NDEs are no more likely to occur in devout believers than in secular or nonpracticing subjects.

Storytelling is essential to living

Stories are the primary way through which we make sense of our world. We explain ideas by telling stories.

Even science uses storytelling when they use data of the physical world to ex...

Where science and story meet

Despite the verities of science, we feel compelled to tell stories that venture beyond the facts.

When we first see separate ideas, we feel obliged to find a relationship between the ideas to form a coherent picture. Once a possible relationship has been established, we feel the need to come up with an explanation.

The brain’s reward system

When the brain pieces separate bits of an image together to form a coherent picture, it is known as pattern recognition. Once we recognize a pattern, it can spark a degree of pleasure, often described as that "a-ha" moment.
