limbic system

Examples of limbic system in the following topics:

• The Limbic System

  • The limbic system combines higher mental functions and primitive emotion into one system.
  • The limbic system is a complex set of structures found on the central underside of the cerebrum, comprising inner sections of the temporal lobes and the bottom of the frontal lobe.
  • There are several important structures within the limbic system: the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.
  • The thalamus, which is a sensory "way-station" for the rest of the brain, is primarily important due to its connections with other limbic-system structures.
  • All the components of the limbic system work together to regulate some of the brain's most important processes.

• Biology of Emotion

  • The limbic system, autonomic nervous system, and reticular activating system interact in the processing of emotion.
  • The limbic system, autonomic nervous system, and reticular activating system all interact to assist the body in experiencing and processing emotions.
  • The limbic system is the area of the brain most heavily implicated in emotion and memory.
  • The processes of the limbic system control our physical and emotional responses to environmental stimuli.
  • The limbic system is the area of the brain involved with emotion and memory.

• Lower-Level Structures

  • It is home to the limbic system, which is considered the seat of emotion in the human brain.
  • The thalamus is part of the limbic system.
  • However, the importance of this structure on the regulation of emotional behavior is not due to the activity of the thalamus itself, but to the connections between the thalamus and other limbic-system structures.
  • When external stimuli are presented (for example, a dangerous stimuli), the hypothalamus sends signals to other limbic areas to trigger feeling states in response to the stimuli (in this case, fear).

• Repressed Memories

  • The limbic system is the part of the brain that is in charge of giving emotional significance to sensory inputs; however, the limbic system (particularly one of its components, the hippocampus) is also important to the storage and retrieval of long-term memories.
  • Supporters of the existence of repressed memories hypothesize that because the hippocampus is sensitive to stress hormones and because the limbic system is heavily occupied with the emotions of the event, the memory-encoding functionality may be limited during traumatic events.

• Conscious vs. Unconscious Emotion

  • The cognition of danger and subsequent arousal of the nervous system (e.g. rapid heartbeat and breathing, sweating, muscle tension) is an integral component to the subsequent interpretation and labeling of that arousal as an emotional state.
  • The limbic system is a complex set of brain structures that includes the hypothalamus, hippocampus, amygdala, and other nearby areas of the brain .
  • The autonomic nervous system, and more specifically the sympathetic nervous system, processes the information and produces reactionary behavior.

• Development of the Human Brain

  • The mental processes and behaviors studied by psychology are directly controlled by the brain, one of the most complex systems in nature.
  • The human brain is one of the most complex systems on earth.
  • The brain and the spinal cord make up the central nervous system, which alongside the peripheral nervous system is responsible for regulating all bodily functions.
  • The forebrain is the most anterior division of the developing vertebrate brain, containing the most complex networks in the central nervous system.
  • The diencephalon is lower, containing the thalamus and hypothalamus (which together form the limbic system); the telencephalon is on top of the diencephalon and contains the cerebrum, the home of the highest-level cognitive processing in the brain.

• Defining Emotion

  • Emotions follow complex biological processes that include several bodily systems.
  • The limbic system includes the amygdala and the hippocampus and functions as the brain’s emotional circuit.
  • The autonomic nervous system (ANS) and reticular activating system (RAS) also play an important role in the experiencing and processing of emotions.

• Biology of Sexual Behavior

  • The biology of human sexuality includes the reproductive system and the sexual response cycle, as well as the factors that affect them.
  • If not fertilized, the egg is flushed out of the system through menstruation.
  • Beneath the cortex is the limbic system, which consists of the amygdala, hippocampus, cingulate gyrus, and septal area.
  • This is the small area at the base of the brain consisting of several groups of nerve-cell bodies that receives input from the limbic system.
  • The female reproductive system consists of both internal organs and external genitalia.

• Olfaction: The Nasal Cavity and Smell

  • The olfactory system gives humans their sense of smell by inhaling and detecting odorants in the environment.
  • This causes foods to taste different if the olfactory system is compromised.
  • This is most likely due to the olfactory system's close anatomical ties to the limbic system and the hippocampus, areas of the brain that have been known to be involved in emotion and place memory.
  • They are processed by an accessory of the olfactory system.
  • The olfactory nerve connects the olfactory system to the central nervous system to allow processing of odor information.

• Short-Term and Working Memory

  • We could roughly say that it is a system specialized for language.
  • The phonological loop and visuospatial sketchpad are semi-independent systems; because of this, you can increase the amount you can remember by engaging both systems at once.
  • The limbic system of the brain (including the hippocampus and amygdala) is not necessarily directly involved in long-term memory, but it selects particular information from short-term memory and consolidates these memories by playing them like a continuous tape.
