an area in the core of the brain that is associated with aggressive behaviors
a limbic system structure that evaluates information from the immediate environment, contributing to feelings of fear, anger, or relief. 83
The portion of the limbic system in the brain that processes emotions.– See also Limbic System
A small almond-shaped structure in the brain which plays a role in emotions and fear control.
A complex grouping of brain cells that, among other things, is thought to be involved in a person's emotional reactions and in coordinating the body's response to stress.
almond-shaped areas the size of a fingernail in the temporal lobes that produce and respond to anger, fear, defensiveness and avoidance. Appears to be activated in anxiety and fear reactions, producing the freeze response, sweaty palms and tense muscles. Prompts the release of adrenaline, which disrupts rational thought.
a structure in the centre of the brain, named for its anatomical resemblance to the almond. It plays a large role in processing emotions, as well as in our defensive behaviour.
A region of the brain, apparently concerned with mood, feeling instinct and possibly memory for recent events. Dysfunctions of the amygdala are apparently linked to depression, anxiety and panic disorders. Anhedonia - Anhedonia derived from the Greek: an, meaning not, and hedone, meaning pleasure. So, taken literally anhedonia means the inability to experience pleasure but in psychiatry it means the loss of pleasure in an activity that has previously been enjoyable.
Structure of the limbic system in the anterior temporal lobe. Also a structure in the basal ganglia.
(Gr. Almond-like): A complex of nuclei located in the dorsomedial temporal lobe just deep to the uncus. This nuclear complex is in contact with the tail of the caudate nucleus and is a component of the basal ganglia known as the archi striatum. It has olfactory, visceral, endocrine, and behavioral functions and may be involved with emotional changes associated with Alzheimer's disease and in Schizophrenia.
neural centre in the limbic system of the brain affecting emotions. Almond-shaped, it is located immediately below the cerebral cortex of the anterior medial temporal lobe. In humans, it is associated with a variety of behaviour patterns including sexuality, aggression, digestion, excretion, arterial blood pressure and muscle tone. Its connection to the hypothalamus has been observed to be related to rage behaviour. Also known as amygdaloid nucleus.
This is a structure in the forebrain. It is part of the limbic system and plays a major role in emotional memory and the response to threat.
Part of the limbic system of the brain. Seizures arising in this area include a rising sensation in the stomach, nausea, movements of the mouth, chewing, fear, panic, and flushing of the face and other autonomic symptoms.
A structure in the forebrain that is an important component of the limbic system.
Meaning almond in Latin, this region of the brain is part of the limbic system, and is implicated in many psychiatric disorders such as schizophrenia and Post Traumatic Stress Disorder (PTSD).
Part of the limbic system always alert to threats.
A discrete brain area that is part of the limbic system, has a large number of dopamine-containing neurons, and plays a role in the learning and performing of certain behaviors in response to incentive stimuli (i.e., motivation, reinforcement).
Coordinates autonomic and endocrine responses in conjunction with emotional states; part of the limbic system.
Almond-shaped part of the brain involved in emotions such as fear.
Brain structure that is part of the limbic system. Implicated in emotion.
This is a pair of structures that exist and an inch or so in from the forehead - there's one on the right side and one on the left side - they supposedly have an impact on moods. The right one is active when a person is depressed, and the left one is active when a person is cheerful. They are associated with fear, and the "fight or flight" response.
A part of the brain that is an important component of the limbic system.
Located in the brain's medial temporal lobe, the almond-shaped amygdala (in Latin, corpus amygdaloideum) is believed to play a key role in the emotions. It forms part of the limbic system. In humans and other animals, it is linked to both fear responses and pleasure. Its size is positively correlated with aggressive behavior across species. In humans it is the most sexually dimorphic brain structure, and shrinks by more than 30% in males upon castration. Conditions such as anxiety, autism, depression, narcolepsy, post-traumatic stress disorder, phobias and schizophrenia are suspected of being linked to abnormal functioning of the amygdala owing to damage, developmental problems, or neurotransmitter imbalance.
A collection of nuclei at the base of the temporal lobe, part of the limbic system. Plays a role in several emotional behaviors such as agression and sexual behavior.
Gr. 'almond'. Nucleus at the tip of the inferior horn of the lateral ventricle ( Ch. 26).
a part of the brain (and part of the limbic system) that is used in emotion.
