What would happen if your thalamus was damaged?

Speech and Cognitive Therapy While thalamus damage primarily causes sensory problems, it can also lead to behavioral and cognitive changes. For example, many patients with a thalamus injury have incorrect speech patterns and can struggle to find the right words. Others display apathy and memory problems.

What is the mid brain?

The midbrain is the topmost part of the brainstem, the connection central between the brain and the spinal cord. Of the 12 cranial nerves, two thread directly from the midbrain – the oculomotor and trochlear nerves, responsible for eye and eyelid movement.

What part of the brain is the thalamus?

diencephalon
The thalamus is a paired gray matter structure of the diencephalon located near the center of the brain. It is above the midbrain or mesencephalon, allowing for nerve fiber connections to the cerebral cortex in all directions — each thalamus connects to the other via the interthalamic adhesion.

What is the thalamus surrounded by?

The thalamus is surrounded by two thin layers of white matter. The grey matter of the thalamus is separated by a Y-shaped layer of white matter called the internal medullary lamina. This structure divides the thalamus into anterior, medial and lateral parts.

Is the thalamus covered by the stratum zonale?

On its superior surface, it is covered by the stratum zonale and on its lateral surface by the external medullary lamina. The grey matter of the thalamus is separated by a Y-shaped layer of white matter called the internal medullary lamina. This structure divides the thalamus into anterior, medial and lateral parts.

Where does the stratum griseum superficiale come from?

Lamina II or SGS, the stratum griseum superficiale (“superficial gray layer”), contains many neurons of various shapes and sizes. Lamina III or SO, the stratum opticum (“optic layer”), consists mainly of axons coming from the optic tract.

Is the spinosum layer in the stratum basale?

The spinosum layer lies just over the stratum basale and is only about five to 10 cells thick. Cells that move into the spinosum layer (which is also known as the prickle cell or squamous cell layer) naturally morph from its initial columnar shape into a polygonal (multi-sided) one.

Where is the stria terminalis located in the thalamus?

The lateral region of the superior surface of the thalamus contains the stria terminalis, a structure that plays a role in the regulation of emotions and behaviors related to stress. Another layer of white matter called the external medullary lamina divides the lateral region of the superior surface from the reticular nucleus.
