Above the midbrain, caudal = posterior. Below the midbrain, caudal = inferior. Dorsal: pertaining to the back or upper surface of the body; opposite of “ventral.” (NCIt) Structures found on the top of the human brain or on the top of some other structure within the brain.
The thalamus, or the dorsal and ventral thalamus collectively, are two oval structures made up of gray matter at the base of the cerebrum. This structure’s primary function is as a relay center through which sensory nerves transmit signals from the spinal cord and brainstem on the way to the cerebral cortex.
When used in reference to the nervous system, dorsal refers to the back when discussing the spinal cord. However, above the junction of the midbrain and diencephalon, dorsal refers instead to the upper or superior portion of the brain.

What is the surface of the brain called?
The surface of the cerebrum is called the cortex. It has a folded appearance with hills and valleys. The cortex contains 16 billion neurons (the cerebellum has 70 billion = 86 billion total) that are arranged in specific layers.
Where is the surface of the brain?
The cortex dominates the exterior surface of the brain. The surface area of the brain is about 233 to 465 square inches (1,500 to 2,000 cm2), which is about the size of one to two pages of a newspaper. To fit this surface area within the skull, the cortex is folded, forming folds (gyri) and grooves (sulci).
What are the surface features of the brain?
The brain’s surface, called the cerebral cortex, is folded into a series of gyri (hills) and sulci (valleys). These features increase the amount of neurons (brain cells) that can fit within the skull. The outer portion of the cortex is made of grey matter, which contains the cell bodies of neurons.

What are the surface features of the brainstem?
The tectum forms the ceiling. The tectum comprises the paired structure of the superior and inferior colliculi and is the dorsal covering of the cerebral aqueduct.
What are the 3 parts of the brainstem and their functions?
The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.
