What is basal ganglia responsible for?
The “basal ganglia” refers to a group of subcortical nuclei responsible primarily for motor control, as well as other roles such as motor learning, executive functions and behaviors, and emotions.
What structures make up the basal ganglia?
The basal ganglia are a cluster of subcortical nuclei deep to cerebral hemispheres. The largest component of the basal ganglia is the corpus striatum which contains the caudate and lenticular nuclei (the putamen, globus pallidus externus, and internus), the subthalamic nucleus (STN), and the substantia nigra (SN).
Is thalamus a part of basal ganglia?
The basal ganglia are situated at the base of the forebrain and top of the midbrain. Basal ganglia are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas.
Is amygdala part of basal ganglia?
The basal ganglia include: corpus striatum. claustrum. the amygdala.
Is the thalamus a gland?
The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The primary function of the thalamus is to relay motor and sensory signals to the cerebral cortex.
Is the amygdala the pineal gland?
Unlike many structures in the brain, the pineal gland is unpaired; in other words, many brain structures like the hippocampus or amygdala are symmetrically paired with another copy of the organ in the other hemisphere of the brain. There is only one pineal gland, however, and it sits right on the midline of the brain.
What happens when the thalamus is damaged?
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 thalamus gland?
What does the thalamus gland do?
Your thalamus is your body’s information relay station. All information from your body’s senses (except smell) must be processed through your thalamus before being sent to your brain’s cerebral cortex for interpretation. Your thalamus also plays a role in sleep, wakefulness, consciousness, learning and memory.
