Where is the subjective experience in the brain?
Current science has no explanation piracetol for subjective experience. There is not even an adequate definition of conscience. Recent research continues with many approaches when trying to find a region of the brain that correlates with consciousness or basic consciousness. To proceed without definitions, the study tries to find a simple consciousness without specific content.
But, recent discoveries show that for most mental events, almost the entire brain is part of large signaling circuits in milliseconds. No modules were found, including the awareness modules. In fact, the integration of all the regions seems to be more relevant than the modules. When someone falls into a coma and anesthesia, the modules appear when people are not fully aware. When they know it, the most widespread integration appears. This post describes the efforts to answer the question: where is the subjective experience in the brain?
How to investigate
B0005622 Improved MRI of the head There has been no evidence of a brain center. Previous theories about which regions of the brain are needed for consciousness have not been explored. An old refuted theory includes the frontal parietal area. Theories of gamma rays correlated with consciousness are outdated. But, research continues in the study of circuits, regions and brain waves. Maybe brain waves in small areas can be relevant.
One way to start looking for a question without definition is to find minimal areas or brain circuits that allow the perception of any type or action that seems to have a purpose. With more capacity to monitor the brain through images, many patients who can not communicate or move (vegetative state) have become sensitized.
Recent research indicates totally different areas of what they were before. Previously, evaluation and monitoring were considered intuitively important. But these do not seem necessary for simple consciousness, but are part of a wider experience. It is possible that the sensory regions are more primary, but it is not clear either.
The perceptions of bigstock Different ways of thinking 43490413 Perceptions have been described in previous articles. Surprisingly, the more descending neurons modulate and determine the results of the sensory information than the ascending information input. The simplest part of having a perception of sound, sight, smell or more complex emotions and thoughts is simply being awake and aware.
The brain regions for general awakening are found in the midbrain. Previous theories of brain regions involved in consciousness include the cortex in the frontal and parietal regions. These also seem to be accessories for primary consciousness. Gamma waves seem to be related to attention, not to basic consciousness. Recently, new research has found other possible regions through the study of vision and hearing.
To study sight and hearing, subjects must usually answer questions about their ability to understand events. In brain injuries called blinds, subjects can answer visual questions without being “aware” that they know what they are observing. Other ways of questioning subjects include scales where they notice how safe they are from a particular observation. All this implies subjectivity. The trick is to try to make objective observations from subjectivity.
