The interthalamic adhesion (also known as the massa intermedia, intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces.
The principal subdivision of the thalamus into nucleus groups is the trisection of each thalamus (left and right) by a Y-shaped internal medullary lamina. This trisection divides each thalamus into anterior, medial and lateral groups of nuclei. [8] The medial group is subdivided into the medial dorsal nucleus and midline group.

PET image of the human brain showing energy consumption The brain consumes up to 20% of the energy used by the human body, more than any other organ. [ 131 ] In humans, blood glucose is the primary source of energy for most cells and is critical for normal function in a number of tissues, including the brain. [ 132 ]
In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...
Mammillary bodies, and their projections to the anterior thalamus via the mammillothalamic tract, are important for recollective memory. [7] According to studies of rats with mammillary body lesions, damage to the medial mammillary nucleus lead to spatial memory deficits.

The thalamic reticular nucleus is part of the ventral thalamus that forms a capsule around the thalamus laterally. However, recent evidence from mice and fish question this statement and define it as a dorsal thalamic structure. [1] [2] It is separated from the thalamus by the external medullary lamina.
