Limbic system Flashcards
What is the primary structure of the limbic system responsible for emotional processing?
Amygdaloid body
The amygdaloid body plays a key role in emotions such as fear and pleasure.
Which part of the limbic system is involved in memory formation?
Hippocampus
The hippocampus is critical for the consolidation of information from short-term memory to long-term memory.
What structure connects the hippocampus to other parts of the limbic system?
Fimbria-fornix
The fimbria-fornix serves as a major output pathway from the hippocampus.
The cingulate gyrus is part of which anatomical structure?
Outer cortical ring
The cingulate gyrus is involved in emotional regulation and processing.
Which area of the limbic system is associated with pleasure?
Septal area
The septal area is known for its role in pleasure and reward mechanisms.
What is the function of the medial forebrain bundle?
Influencing visceral motor neurons
This bundle projects to the hypothalamus and brainstem, affecting autonomic functions.
Which structure in the diencephalon is crucial for regulating autonomic functions?
Hypothalamus
The hypothalamus plays a key role in homeostasis and the regulation of bodily functions.
What are the two primary sensory systems that the limbic system receives impulses from?
Olfactory and auditory systems
These sensory inputs are essential for emotional responses and memory association.
What are the pain centers located in the limbic system?
Lateral hypothalamus
The lateral hypothalamus is involved in pain perception and response.
Fill in the blank: Diseases of the _______ lobe or hippocampus result in focal seizures and abnormal behavior.
piriform
The piriform lobe is involved in olfactory processing and can affect behavior when damaged.
True or False: Amygdalectomy leads to increased aggression and sexual behavior.
True
Removal of the amygdala can result in loss of fear and increased hypersexuality.
What syndrome is associated with the English springer spaniel?
Rage syndrome
This syndrome is characterized by sudden aggressive outbursts in affected dogs.
Which neurotransmitter’s excess levels make the hippocampus vulnerable to toxicity and necrosis?
Glutamate
Excessive glutamate can lead to neurotoxicity and damage in the hippocampus.
Which limbic structure is involved in focal seizures when stimulated?
Cingulate gyrus
Stimulation of the cingulate gyrus can trigger abnormal electrical activity leading to seizures.
