To tell the truth, the plot of the movie itself is not too attractive, nor is it very good, and the plot is full of various routines, which can only be said to be quite satisfactory.
The sole purpose of my review here is to discuss a theme in the film, namely whether a person's memory personality and emotions can be shaped and transplanted by duplicating the frontal lobe.
According to a quote from Wikipedia: The
frontal lobe is a part of the vertebrate brain, located in the front half of the brain (in front of the parietal lobe, above the temporal lobe), and is the largest in the human brain compared to the "lobes" in the rest of the brain part of the brain, while some animals have almost no frontal lobes.
This structure is related to the formation of human language, language expression (Broka's area), autonomous consciousness, and control of voluntary muscles.
It is obvious that both long-term memory and short-term memory are not stored in the prefrontal cortex, but are stored in the hippocampus of the limbic system. This is a structural flaw in this movie. The frontal lobe electrical circuit transplant is not a brain replacement operation, and the consciousness of the hippocampus has not been uploaded. How can the memory be transferred?
Frontal lobe: It is the center of movement and thinking. When she is injured, it is easy to cause motor hemiplegia in the lower half of the contralateral face and the contralateral limbs, spasms and even convulsions, in addition to incontinence and personality changes. Since the dominant brain of most people is on the left side, damage to the left frontal lobe will cause motor aphasia. The patient may understand and understand, but cannot speak or write, so the patient is also prone to depression and depression. . The left frontal lobe is also the center of calculation, reasoning, and abstract ideas, so after damage, it will not be able to do arithmetic, think carefully, and be unable to understand the meaning of commonly used idioms (Note 2). However, damage to the right frontal lobe can lead to a lack of space, three-dimensional perception, and even inability to draw. In addition, patients with right frontal lobe damage may experience excessive euphoria, resulting in exaggerated or indifferent emotional expressions. The above anthology describes a review of patients with frontal lobe damage. From this, we know that the successful transplantation of the frontal lobe circuit only prompted the male protagonist Jericho to obtain the behavioral inertia and emotional inertia of the second male Bill. In addition, the description of Jericho before the development of the frontal lobe in the film is very realistic. , patients with undeveloped frontal lobes are often hysterical, have no perception of good and evil, abnormal mood swings, inability to count and think critically, and beasts without empathy, which is typical of patients with congenital damage or undeveloped frontal lobes Performance.
But this still can't change a logical flaw in the movie. This kind of transplantation will not bring about the transfer of actual memory, but will only produce the phenomenon of personality communion. Jericho is implanted with a virtual emotional personality , rather than its memory, the transplanted effect will be the imprint of action and emotion, which is a vague electrical circuit information of the picture system, and there will be no clear memory structure to be transmitted.
And this is the biggest logical flaw in the movie.
However, this film does have a bright spot, that is, the fusion process after Jericho's personality is implanted, which is very realistic, from the morbid frontal lobe damaged patients, beast-like behavior, to the generation of multiple personality structures and behavioral chaos. Then, when the personality gradually merges and the frontal lobe is repaired, the behavior is gradually normalized, and the emotional fluctuation response is gradually normalized.
In addition, to be honest, the layout of this film is a bit too big, and the rhythm of the other film about the brain is not as well grasped.
