The parts of the brain that perform the functions that Freud called the “id” are located mainly in the ERTAS and limbic system, whereas the parts that perform the functions he attributed to “the repressed” (or the “system unconscious”) are located mainly in
the basal ganglia and cerebellum
.
Which part of the brain controls consciousness?
The brain stem
connects the cerebrum with the spinal cord. It contains a system of nerve cells and fibers (called the reticular activating system) located deep within the upper part of the brain stem. This system controls levels of consciousness and alertness.
What part of the brain regulates unconscious biological functions?
The medulla
is largely responsible for unconscious biological functions such as breathing, heart and blood vessel activity, swallowing, vomiting, sneezing, and coughing. The pons connects the brainstem to the cerebellum and assists in coordination of movement, sleep respiration, appetite, and facial sensations.
Which part of the brain regulates basic biological needs?
The brain stem
is the oldest and innermost region of the brain. It's designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 4.7, “The Brain Stem and the Thalamus”).
What part of the brain controls unconscious functions such as heart rate and breathing?
Medulla
– The primary role of the medulla is regulating our involuntary life sustaining functions such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.
What happens to the brain when unconscious?
“We found that during unconsciousness, disrupted connectivity in the brain and greater modularity are
creating an environment that is inhospitable to the kind of efficient information transfer that is required for consciousness
.”
What is the function of the unconscious mind?
The unconscious mind is a
reservoir of feelings, thoughts, urges, and memories that are outside of our conscious awareness
. The unconscious contains contents that are unacceptable or unpleasant, such as feelings of pain, anxiety, or conflict.
What part of the brain controls vision and hearing?
Cerebrum
: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
What part of brain is responsible for waking up?
One of the major systems in the brain that wakes you up is called
the reticular activating system, or RAS
. The RAS is a part of your brain located just above your spinal column. It's about two inches long and the width of a pencil.
Which lobe of the brain controls emotions?
The frontal lobes
are considered our emotional control center and home to our personality.
What is the most primal part of the brain?
A modern brain and a primal brain. Your modern brain (frontal cortex) is responsible for problem solving, memory, language, judgment, impulse control, and reasoning. Your primal brain (
hindbrain and medulla
) is responsible for survival, drive, and instinct.
What is the ultimate function of the brain?
The brain is arguably the most important organ in the human body. It
controls and coordinates actions and reactions
, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
Which part of the brain regulates heart rate?
The brain stem
sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
Which part of the brain controls all involuntary actions?
The medulla oblongata
is the part of the brain which is responsible for controlling all the involuntary actions of the body.
How long can you be unconscious before brain damage occurs?
Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only
4 minutes
without oxygen, and death can occur as soon as 4 to 6 minutes later. Machines called automated external defibrillators (AEDs) can be found in many public places, and are available for home use.
Can you be awake while unconscious?
Lethargy
is a state of being awake, but with diminished alertness and diminished ability to respond. After recovering from unconsciousness, it usually takes hours, days, or longer to regain full awareness and ability to respond.
