amygdala

(noun)

Located in the medial temporal lobe, this brain region is believed to play a key role in emotions such as fear and pleasure in both animals and humans.

Examples of amygdala in the following topics:

  • Limbic System

    • It includes the hippocampus, amygdala, anterior thalamic nuclei, septum, limbic cortex, and fornix, and supports a variety of functions including emotion, behavior, motivation, long-term memory, and olfaction.
    • Amygdala: Involved in signaling the cortex of motivationally-significant stimuli, such as those related to reward and fear, and in social functions, such as mating.
    • The septal nuclei receive reciprocal connections from the olfactory bulb, hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus.
  • Cephalic Phase

    • Neurogenic signals that initiate the cephalic phase of gastric secretion originate from the cerebral cortex, and in the appetite centers of the amygdala and hypothalamus.
  • The Brain

    • The amygdala is a small, almond-shaped structure deep inside the anteroinferior region of the temporal lobe.
    • The amygdala is the center for danger identification, a fundamental part of self-preservation.
  • The Synapse

    • These are found in stereotyped movements as in jerky movements of the eye and in hippocampus and amygdala where emotions and memory is processed.
  • Disorders of the Basal Ganglia

    • Other motor deficits and common non-motor features of Parkinson's, such as autonomic dysfunction, cognitive impairment, and gait/balance difficulties, are thought to result from widespread progressive pathological changes commencing in the lower brain stem and ascending to the midbrain, amygdala, thalamus, and ultimately the cerebral cortex.
  • Amnesia

    • H.M. developed pronounced anterograde amnesia after his hippocampus and amygdala were removed to treat severe epilepsy.
  • Stress and Disease

    • The regions of the brain involved in memory processing that are implicated in PTSD include the hippocampus, amygdala, and frontal cortex, while the heightened stress response is likely to involve the thalamus, hypothalamus, and locus coeruleus.
  • Hypothalamus

    • The hypothalamus is thus richly connected with many parts of the central nervous system, including the brainstem, reticular formation and autonomic zones, and the limbic forebrain (particularly the amygdala, septum, diagonal band of Broca, olfactory bulbs, and cerebral cortex).
  • Overview of the Cerebrum

    • The olfactory bulb also receives "top-down" information from such brain areas as the amygdala, neocortex, hippocampus, locus coeruleus, and substantia nigra.
  • Cerebral Lobes

    • The temporal lobe contains the hippocampus and plays a key role in the formation of explicit long-term memory, modulated by the amygdala.
