Chapter 58 -Guyton and Hall, Textbook of Medical Physiology, 12th edition -Unit Ten: The Nervous System

AB
What plays an important role in causing dreaming, and rapid eye movement sleep (REM sleep)?the locus ceruleus.
Destruction of the dopaminergic neurons in the substantia nigra is the basic cause ofParkinson’s disease.
The raphe nuclei controlsthe serotonin system.
The raphe nuclei secretsserotonin.
The serotonin released in the diencephalon and cerebrum help causenormal sleep.
The gigantocellular neurons secretacetylcholine.
Activation of the gigantocellular neurons acetylcholine neurons release leads toan acutely awake and excited nervous system.
The limbic system neuronal circuitry controlsemotionalbehavior and motivational drives.
The hypothalamic infundibulum control the secretions of the theanterior and posterior pituitary.
The hippocampus is responsible forcritical decision-making neuronal mechanism.
What causes translation of short-term memory into long-term?the hippocampus.
Consolidation of long-term memories of the verbal or symbolic thinking takes place in thehippocampus.
The basolateral nuclei of the amygdala play important roles inbehavioral activities.
Stimulation of other amygdaloid nuclei can give reactions ofreward and pleasure.
Stimulation the amygdaloid nuclei can causeof rage, escape, punishment, severe pain, and fear.
Amygdala stimulation can causeinvoluntary movements.
Bilateral ablation of the Amygdala causesKlüver-Bucy Syndrome.
Ablation of the anterior temporal cortex also damages thethe amygdalas.
Ablation of the posterior orbital frontal cortex causesinsomnia associated with intense motor restlessness.
Ablation of the anterior cingulate gyri and subcallosal gyri causesrelease of the rage centers from the prefrontal inhibitory influence.
The anterior temporal cortex controlsthe gustatory and olfactory behavioral associations
In the middle and posterior cingulate cortex coordinatessensorimotor behavioral associations.
