The Limbic System Revision

The following is a plain text extract of the PDF sample above, taken from our Neurology Notes. This text version has had its formatting removed so pay attention to its contents alone rather than its presentation. The version you download will have its original formatting intact and so will be much prettier to look at.

Anatomy
 Hippocampal fibres go via fornix to mammillary bodies of hypothalamus
 MB project via mammillothalamic tract to anterior thalamic nuclei (AT)
 Fibres from AT project to cingulate gyrus via internal capsule
 White matter pathway; cingulum bundle from cingulate cortex to parahippocampal gyrus and then to hippocampus Function
 Thought to principally be involved in emotional processing but is NOT
 Expanded to include

• Septal Nuclei

• Ventral striatum

• Prefrontal cortex

• Amygdala
 Structure in circuit critical for MEMORY not emotion Present model

The Limbic system o Components (diverse set of cortical & subcortical structures; medial & ventral)
 Prefrontal cortex
 Parahippocampal gyrus; Hippocampus
 Septal nuclei and nucleus accumbens
 Amygdala
 Hypothalamus
 Thalamus
