|
All limbic system connections ultimately project to the..
|
Hypothalamus
|
|
|
Entry of information into the limbic system is to the... (direct and indirect)
|
directly to the amygdala or indirectly to to the hippocampal formation via the entorhinal area
|
|
|
the limbic system can influence motor responses via projections to...
|
the nucleus accumbens, which forms part of the basal ganglia
|
|
|
what are the afferents to the amygdala?
|
from inferior temporal association complex, the septum, the olfactory tract, has catecholamine and serotonin projections from the fore brain bundle of the brain steam.
|
|
|
What are the Amygdala efferents?
|
stria terminalis (in wall of lateral ventricle to hypothalamus) and amygdalofugal path to hypothalamus
|
|
|
Where is the Amygdala?
|
near temporal pole between inferior horn of lateral nucleus and the lentiform nucleus.
|
|
|
Where is the septum?
|
beneath the rostral part of the corpus callosum
|
|
|
What are the connections of the septum?
|
1 - connects with amygdala and projects to hypothalamus via the medial forebrain bundle. 2 - with the monoaminergic nuclei of the brain stem via fibres to the habenular nuclei of diencephalon as the stria medullaris thalami. the habenular nuclei then project to the interpeduncular nuclei with in turn projects to the brain steam.
|
|
|
What makes up the hippocampal formation?
|
The Hippocampus, the dentate gyrus and parts of the parahippocampal gyrus.
|
|
|
The hippocampus is formed by...
|
the folding of the temporal lobe into the lateral fissure along the line of the choroid fissure.
|
|
|
The dentate gyrus lies between which two structures?
|
the parahippocampal gyrus and the hippocampus.
|
|
|
What are the afferents to the hippocampal formation?
|
1 - fibres from the inferior temporal cortex via the entorhinal area of the temporal lobe. 2 - from the countralateral entorhinal area 3 - the hippocampus via the fornix and hippocampal formations
|
|
|
What are the efferents from the hippocampal formation?
|
Primary efferent = fornix
|
|
|

|
|
|
What are the efferents from the hippocampal formation?
|
Primary efferent = fornix
|
|
|
what two structures does the fornix link?
|
the hippocampus and the mammillary body of the hypothalamus.
|
|
|
How do efferent fibers pass from the hippocampus to the fornix?
|
via the fimbrai
|
|
|
Where does the mammillary body project to?
|
1 - the anterior nucleus of the thalamus via mamillothalamic tract 2 - brain steam via mammillotegmental tract
|
|
|
How are the cingulate gyrus and the parahippocampal gyrus connected?
|
The are continuos around the splenum of the corpus callosum.
|
|
|
What is the Papez circuit?
|
the connections of the principle structures of the limbic system.
