The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. This sensation is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
In this way, what sense does not go through the thalamus?
The sense that does not go through the thalamus is smell. Smell is detected by chemoreceptors in the olfactory epithelium in the nose.
Also, does the thalamus control breathing? The thalamus is involved with sensory signals sent to the higher forebrain, in particular the cerebral cortex. The brain stem is made up of the midbrain, pons and medulla oblongata. It carries out many vital functions of the body for maintenance and survival such as breathing, heartbeat, and blood pressure.
Besides, what does the thalamus control in the brain?
Thalamus is involved in sensory as well as motor functions of the brain. It is the part of the brain where the sensory information from all over the body converge and are then sent to various areas of the cortex. It also helps the motor cortex for coordinated voluntary movements of the part.
What senses are routed through the thalamus?
Answer and Explanation: All of the senses are routed through the thalamus except the sense of smell. The sense of smell is controlled by the olfactory bulb.

What lobe is the thalamus in?
The thalamus is a structure in the middle of the brain. It is located between the cerebral cortex and the midbrain. It works to correlate several important processes, including consciousness, sleep, and sensory interpretation.
Does the thalamus process hearing?
Primary Auditory Pathway This pathway carries messages from the cochlea to a sensory area of the temporal lobe called the auditory cortex. The thalamus integrates the sensory systems in the body and hence functions as an essential factor in the preparation of a motor response e.g. vocal response.
How is the thalamus used in everyday life?
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. The thalamus also plays a significant role in sensory perception and movement.
Does Vision go through the thalamus?
For example, visual information from your retina travels to the lateral geniculate nucleus of the thalamus, which is specialized to handle visual information, before being sent on to the primary visual cortex (the main area for visual processing in the brain).
Can you recover from a thalamic stroke?
Following a thalamic stroke, full recovery can take anywhere from a week or two to several months. Depending on how severe the stroke was and how quickly it was treated, you may have some permanent symptoms.
Where is the right thalamus?
The thalamus is located deep within the brain in the cerebral cortex, adjacent to the hypothalamus. It is a symmetrical structure, situated on top of the brain stem and on either side of the third cortex.
Does taste go to thalamus?
Like many sensory systems, taste is projected through the dorsal brainstem or spinal cord, to the thalamus, and then on to sensory cortical areas.
Does smell pass through thalamus?
Odors in the Brain Smell information also goes to the thalamus, a structure that serves as a relay station for all of the sensory information coming into the brain. The thalamus transmits some of this smell information to the orbitofrontal cortex, where it can then be integrated with taste information.
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 thalamus serves as a sensory relay center; its neurons project signals to both the amygdala and the higher cortical regions for further processing.
How does the thalamus affect behavior?
The thalamus is a heterogeneous assembly of well-organized nuclei, which receives and processes sensory and motor input signals and has reciprocal connections with the cerebral cortex. It transmits the sensory information to the cortex and is involved in motor, arousal, and mood functions.
How does the thalamus regulate sleep?
The role of thalamus in sleep The opening of the sleep gate for nonrapid eye movement sleep is a thalamic function but it is assisted by melatonin which acts by promoting spindle formation. Thus, melatonin has a modulatory influence on sleep onset and maintenance.
Does the thalamus control temperature?
Homeostasis: the ability to keep a system at a constant condition. Hormone: a chemical message released by cells into the body that affects other cells in the body. Hypothalamus: a part of the brain that controls things like thirst, hunger, body temperature, and the release of many hormones.
What does the cerebral cortex control?
The cerebral cortex is responsible for many higher-order brain functions such as sensation, perception, memory, association, thought, and voluntary physical action. The cerebrum is the large, main part of the brain and serves as the thought and control center.
What happens if your cerebral cortex is damaged?
Damage to the sensory cortex results in decreased sensory thresholds, an inability to discriminate the properties of tactile stimuli or to identify objects by touch. The somatosensory association cortex (areas 5 and 7) is directly posterior to the sensory cortex in the superior parietal lobes.
