What part of your brain controls reaction?
The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.
What part of the brain processes sensory information?
The parietal lobe is located in the middle section of the brain and is associated with processing tactile sensory information such as pressure, touch, and pain. A portion of the brain known as the somatosensory cortex is located in this lobe and is essential to the processing of the body’s senses.
How does the brain process emotions?
The main part of the brain responsible for processing emotions, the limbic system, is sometimes called the “emotional brain” [source: Brodal]. Part of the limbic system, called the amygdala, assesses the emotional value of stimuli.
How does the brain control reflexes?
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
Where is the emotional center of the brain?
amygdala
The amygdala is a small almond-shaped structure; there is one located in each of the left and right temporal lobes. Known as the emotional center of the brain, the amygdala is involved in evaluating the emotional valence of situations (e.g., happy, sad, scary).
Is the brain involved in a reflex reaction?
This quick response is called a reflex, and reflexes occur without conscious thinking or planning, meaning the brain is not involved in them.
What part of the nervous system is responsible for reflexes?
The part of the brain that controls reflexes is the cerebellum. The cerebellum regulates motor reflexes and is also involved in the synchronization of balance and muscles. The brainstem links and transmits messages to the spinal cord from the brain, regulating functions such as respiration, heart rate, and alertness.
How long does it take your brain to react to a stimulus?
The average reaction time for humans is 0.25 seconds to a visual stimulus, 0.17 for an audio stimulus, and 0.15 seconds for a touch stimulus. Concise Handout for the Classroom This handout was designed by Virginia Johnson, a graduate student who adapted our experiment here to use as a teaching tool.
Where does information processing start in the brain?
As you learn about the brain, keep in mind that the usefulness of these metaphors is limited and can lead to erroneous conclusions. Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals.
Where does the fear response start in the brain?
Fear reaction starts in the brain and spreads through the body to make adjustments for the best defense, or flight reaction. The fear response starts in a region of the brain called the amygdala.
Which is part of the brain responds to stimuli?
This response is generated by stimulation of the amygdala, followed by the hypothalamus. This is why some people with brain damage affecting their amygdala don’t always respond appropriately to dangerous scenarios.
