The basal ganglia are a cluster of nuclei located deep within the cerebral hemispheres, wrapped around the thalamus and lateral ventricles.

Consider:

How do the caudate nucleus and putamen form a curved shape around the lateral ventricles?

Why does the internal capsule separate different parts of the basal ganglia?

How does the positioning of the substantia nigra in the midbrain relate to Parkinson’s disease?

Multimedia Suggestions: Post an annotated CT or MRI scan, use Visible Body to rotate and highlight their deep position, or create a video tracing their connections in 3D.

Peer Engagement Instructions:

Step 1: Explore in 3D – Before commenting, review at least five posts and think about spatial relationships:
Can you see how these structures wrap around or interact with others?
How do different students' perspectives help clarify complex 3D relationships?

Step 2: Engage Meaningfully – Respond to at least two peers by:
Asking a spatial-focused question (e.g., "How does the curved shape of the caudate nucleus affect its relationship with the ventricles?")
Expanding their post with a 3D insight (e.g., "Great breakdown of the limbic system! The hippocampus also curves along the floor of the lateral ventricle, which is important for its placement.")
Linking their post to real-world imaging or clinical cases (e.g., "Your post on the basal ganglia made me think of Huntington’s disease, which affects the caudate nucleus—how does its shape change in this condition?")

The limbic system is not a single structure—it is a network of interconnected regions spread throughout the deep brain.

Consider:

How do the hippocampus, amygdala, and cingulate gyrus wrap around other deep brain structures?

Why is the fornix important for connecting parts of the limbic system?

How does the limbic system's deep location explain why emotions can be linked to memory?

Multimedia Suggestions: Use Visible Body to show the spatial layout, draw a 3D concept map

The pineal gland is a small, midline structure located between the two superior colliculi, just posterior to the third ventricle.

Consider:

Why is the pineal gland a useful midline landmark in imaging (especially in CT/MRI scans)?

How does the third ventricle’s location relate to the pineal gland?

Why does pineal gland calcification appear on X-rays as people age?

Multimedia Suggestions: Create a labeled cross-section, use Visible Body to rotate and highlight its midline position, or post a CT/MRI/US scan showing the pineal gland as a landmark.
