The dorsal raphe nucleus is which region of reticular formation?
The reticular activating system
The lateral reticular formation
The medial reticular formation
The median reticular formation
It is NOT a member of the reticular formation
When the mesopontine cholinergic fibres are active, and the locus coeruleus are inactive, what state of sleep exists?
This does not occur
This occurs only in light sleep
This occurs in light sleep and deep REM sleep
This occurs in deep REM sleep
This occurs in biphasic sleep and wakefulness
Wakefulness involves which reticular formation constituents?
Mostly median nuclei
A model for reticular formation implication of the pathogenesis of schizoid disorders include
FGF23 causes a decrease the mesopontine projectile cholinergic population
ACh blockade occurs in the nucleus basilis Meynert
Mesopontine fibres have similar projection effect on the prefrontal cortex as mesocortical fibres
There is a reduction in developmental apoptosis of mesopontine cholinergic projection neurons
None of the above
Which particular glucocorticoid receptor subtype locations are implicated in working models of the reticular formation role in post traumatic stress disorder?
Which portion of the amygdaloid complex is associated intimately with cardiorespiratory regulation?
The fimbriae-fornix complex is responsible for connecting which two subcortical structures?
Entorhinal cortex and amygdala
Amygdala and hippocampus
Posterior commissure and habenulointerpeduncular tract
Hippocampus and mammillary bodies
Anterior thalamus and stria medullaris
Which is the most critical afferent connection for the hippocampus to receive information?
The efferent hippocampal complex information projects to two regions. The first the mammillary bodies, the second are septal nuclei located ...
About the posterior perforated substance
Within the basalis pontis
Deep to the uncus
Within the parahippocampal gyrus
Within the subcallosal region
A patient with a sudden intense interest in religion, desire to draw and reduction of libido would most likely have a bespoke lesion to which tract network?
Anterior thalamic projections
Question 10 Explanation:
The uncinate fasciculus connects the orbitofrontal cortex and amygdala. The condition above is Gershwind's syndrome.
