A brain that remembers celebrities

Updated: May 29, 2022

Studying the "Study of Consciousness" (Stanislas Duanne) can further deepen your understanding of coaching theory.

I am studying to add a unique flavour to "unconscious rewriting".


This series of blog posts are my study notes. This time, the theme that follows the unconscious and conscious

I will write a "sign of consciousness".


 

If the cells in the anterior temporal lobe encode conscious perception, the discharge must be independent of how consciousness is manipulated.

Dr Fried and colleagues have found that firing of these neurons also correlates with conscious perception when non-masking methods are applied, such as binocular struggle.



"Bill Clinton cells" (referring to celebrities) were discharged only when the face of former President Clinton presented was to one eye.


When the chessboard image presented to the other eye and the former president's face was removed from the field of vision by a binocular struggle, the discharge stopped immediately.


The face of the former president should be visible on the retina. But we erased competing images, and our imaging activation could not reach the higher cortical centres.


Whether active or inactive, the patterns that cells make up internal form codes that represent the content of subjective perceptions, such as the face of a former president.


The code of this consciousness is stable and playable.

When the patient thinks about the face of the former president, the same cells fire.



Even if there is no external objective stimulus input, just thinking of his face activates the cell.

The majority of the anterior temporal lobe neurons respond the same to both real and imaginary images.


Our images may also activate by remembering the memory.

For example, a cell ignited while the patient watched a video of The Simpsons being discharged again every time he remembered the scene in the dark.



Conscious information is thought to be dispersed in a myriad of cells.

Millions of neurons scattered throughout the relevant cortical area encode fragments of the external scene.


Synchronous discharges by these neurons produce macroscopic brain potentials.

Unfortunately, it seems impossible to detect the firing of a single cell at a distance. Still, conscious perception mobilizes a large cell population, so the sizeable potential terrain released by the visual cortex ( Based on (topography), it is possible to determine whether the subject is looking at a face or a building.


Distinguishing spikes that encode conscious perceptual representations has three characteristics: (1) temporal stability, (2) reproducibility between trials, and (3) invariance that maintains content beyond superficial changes. You also need to identify a series of spikes.


For example, the posterior cingulate cortex activity, which is located on the midline of the parietal cortex and is highly integrated, meets these requirements.

The neural activity caused by visual stimuli is stable even if the eyes move, as long as the subject itself does not move.

Neurons in this area are aligned with objects in the outside world and can maintain firing homeostasis as we look around.


The posterior cingulate gyrus, with cells tracking a constitutive position, is called the parahippocampal gyrus. And they are closely associated with the tissue adjacent to the hippocampus that holds the "place cells."


Shortly, it may be possible to break abstract code that encrypts the skeleton of thought.
