Description

Amygdala

62

61

Defined anatomically.  Traced in coronal view.

Ant: presence of anterior commissure, slice w/ brightest medial point

Post: slice where any hippocampus is visable

Sup: medially by the entorhinal sulcus, Laterally, draw a line from lateral point of ES to white matter of insular cortex

Inf:  white matter of the uncus

Med: CSF

Lat:  white matter of insular cortex

Nucleus Accumbens

64

63

Defined anatomically.  Traced in coronal view.

Ant: rostral end of ventral caudate/putamenal junction

Post: last slice with the midline decussation of AC

Sup: line that connects the inferiormost tip of the lateral ventricle to the ventral point of the IC.

Inf: white matter

Med: line which includes all gray matter next to the white matter tract

Lat: vertical line drawn from tip of internal capsule to the white matter

Orbital Frontal Cortex

66

65

Defined anatomically.  Traced in coronal view.

Lat: Intermediate, lateral orbital sulcus; Anterior, frontomarginal sulcus; Posterior, orbito insular sulcus

Med: Anterior, superior rostral sulcus; Posterior & Intermediate, olfactory sulcus

Post: most posterior coronal slice containing some aspect of the posterior medial OFG

Superior Frontal Cortex

68

67

Defined anatomically.  Traced in coronal view.

Ant:vVaries.  Typically the frontomarginal sulcus or superior rostral sulcus

Post: anterior tip of inner surface of CC

Inf: Posterior, cingulate sulcus; Anterior, superior rostral sulcus

Med: superior margin of the hemisphere

Lat: Deepest point of superior rostral sulcus

Hippocampus

70

69

Defined anatomically.  Traced in coronal view.

Ant: sagittal slice where the temporal horn of the lateral ventricle curves downwards at a 90 degree angle

Post: last viewable coronal slice w/ hippocampus

Sup: follow the alveus

Inf: white matter located inferior to hippocampus.  Include subiculum

Med: CSF inuncal cistern.  Include subiculum

Lat: CSF of temporal horn of lateral ventricle. 

Parahippocampal Gyrus

71

Defined anatomically.  Traced in coronal view.

Ant: temporal horn of lateral ventricle

Post: first view of calcarine sulcus

Sup: subliculum

Inf: end of cerebrum, no uncus

Med: CSF in uncal cistern

Lat:  beginning of collateral sulcus, straight line to hippocampus

Inferior Frontal Gyrus

74

73

Defined anatomically.  Traced in axial view.

Ant: vertical line from anterior tip of inferior frontal sulcus to frontomarginal sulcus or lateral orbital sulcus

Post: precentral sulcus

Sup: inferior frontal sulcus that runs anterior & perpendicular to the inferior segment of the precentral sulcus

Inf: frontromarginal sulcus or lateral orbital sulcus in the anterior part or the superior circular sulcus of insula at level of the frontal operculum

Med: circular sulcus of insula

Lat: meeting of inferior frontal sulcus & precentral sulcus
