Why do we lose consciousness when we sleep
Technically sleep starts in the brain areas that produce SWS.
Scientists now have concrete evidence that two groups of cells—the ventrolateral preoptic nucleus in the hypothalamus and the parafacial zone in the brain stem—are involved in prompting SWS.
When these cells switch on, it triggers a loss of consciousness..

According to Freud, thoughts and emotions outside of our awareness continue to exert an influence on our behaviors, even though we are unaware (unconscious) of these underlying influences. The unconscious can include repressed feelings, hidden memories, habits, thoughts, desires, and reactions.
Do conscious thoughts cause behavior
Everyday intuitions suggest full conscious control of behavior, but evidence of unconscious causation and automaticity has sustained the contrary view that conscious thought has little or no impact on behavior.
Where is your soul located
The soul or atman, credited with the ability to enliven the body, was located by ancient anatomists and philosophers in the lungs or heart, in the pineal gland (Descartes), and generally in the brain.
Is consciousness the same as awareness
Scientists differ on the difference between consciousness and self-awareness, but here is one common explanation: Consciousness is awareness of one’s body and one’s environment; self-awareness is recognition of that consciousness—not only understanding that one exists, but further understanding that one is aware of …
What affects consciousness
There are a number of things that can cause changes or alterations in consciousness. Some of these occur naturally, while others are the result of things such as drugs or damage to the brain. Changes to consciousness can also result in changes in perception, thinking, understanding, and interpretations of the world.
What part of the brain controls consciousness
cerebrumThe brain gives us self-awareness and the ability to speak and move in the world. Its four major regions make this possible: The cerebrum, with its cerebral cortex, gives us conscious control of our actions. The diencephalon mediates sensations, manages emotions, and commands whole internal systems.
Where does conscious thought come from
All kinds of mental imagery, such as inner speech or visual memory, can of course be conscious. We see things in our mind’s eye; we hear our inner voice. What we are conscious of are the sensory-based contents present in working memory.

What are the two aspects of consciousness
Consciousness is a multifaceted concept that has two dimensions: arousal, or wakefulness (i.e., level of consciousness), and awareness (i.e., content of consciousness). One needs to be awake in order to be aware (rapid eye movement (REM) sleep and lucid dreaming being notorious exceptions).

What is the role of consciousness
Consciousness is associated with a flexible response mechanism (FRM) for decision-making, planning, and generally responding in nonautomatic ways. The FRM generates responses by manipulating information and, to function effectively, its data input must be restricted to task-relevant information.
What is conscious thinking
We see conscious thought as the place where the unconscious mind assembles ideas so as to reach new conclusions about how best to behave, or what outcomes to pursue or avoid. Rather than directly controlling action, conscious thought provides the input from these kinds of mental simulations to the executive.
