What tracts go through the thalamus?

What tracts go through the thalamus?

It transmits information to the thalamus about pain, temperature, itch and crude touch. There are two main parts: the lateral spinothalamic tract, which transmits pain and temperature, and the anterior (or ventral) spinothalamic tract, which transmits crude touch and pressure.

What are the thalamic structures?

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 are the three main types of thalamic nuclei?

Each side can divide into three groups of thalamic nuclei: a lateral nuclear group, a medial nuclear group, and an anterior nuclear group. These three groups get split by the internal medullary lamina, a Y-shaped structure present on each side of the thalamus.

What are the thalamic nuclei?

“Sensory” thalamic nuclei connect sensory input to the cerebral cortex. These nuclei include the medial geniculate nucleus (MGN; auditory), lateral geniculate nucleus (LGN; visual), and the ventrobasal complex (VB, also known as the ventral posterior nucleus; somatosensory and vestibular).

Does the thalamus control emotions?

The limbic system is the area of the brain most heavily implicated in emotion and memory. Its structures include the hypothalamus, thalamus, amygdala, and hippocampus. The hypothalamus plays a role in the activation of the sympathetic nervous system, which is a part of any emotional reaction.

How does the thalamus affect you?

The thalamus plays a role in our memory, emotions, sleep-wake cycle, executive functions, processing sensory input, and sensorimotor control. When a stroke affects the thalamus, it can impair some of these functions — especially the processing and transmission of sensory information.

How is the thalamus used in everyday life?

The thalamus is extremely important to the regulation of the human nervous system. It is the center of information processing, and is what maintains consciousness, organizes subconscious information and regulates the very survival of the human being.

What part of the brain controls moods and emotional behavior?

The limbic system
The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.
