Where and What is the Thalamus?From News-Medical.Net: The thalamus is a small structure(highlighted green) within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex. It also regulates sleep, alertness and wakefulness.
Because of the tumor's location removal is not an option.
What is an Astrocytoma?
Astrocytomas are tumors that grow from a type of cell in the brain called an astrocyte. Throughout the brain and spinal cord we all have nerve cells called ‘neurons’, which transmit messages (electrical and chemical signals) to, from and within the brain. Surrounding the neurons are cells called ‘glial cells’, that support and protect the neurons by providing them with oxygen and nutrients and removing dead cells. An astrocyte is a type of glial cell. Astrocytes are the most abundant cells in the brain, and as well as supporting and protecting neurons, they also help to pass messages between the neurons and, therefore, are vital in processing information in the brain.
