The pons, while involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement (REM) sleep.

How is pons used in everyday life?

The pons also serves to connect the cerebral cortex to the medulla oblongata via the cerebral peduncles. The pons is involved in many autonomic and sensory functions including arousal, respiratory processes, fine motor control, equilibrium, muscle tone, and the Circadian cycle (specifically regulating sleep).

Can you live without a pons?

Because of the part that the Pons plays in hearing, eating, facial expression, and eye movement, the Pons is NOT something you could live without. It relays messages throughout the brain and controls too many important vital functions we as human beings need.

What is the function of the pons in psychology?

Pons: n. a structure on the brain stem that lies above the medulla and regulates sleep, arousal, consciousness, and sensory processes.

What will happen if pons is damaged?

Pons also relays sensory information and signals governing sleep patterns. If pons is damaged, it may cause loss of all muscle function except for eye movement.

Why is pons called bridge?

Pons is Latin for “bridge”; the structure was given its name by the Italian anatomist Costanzo Varolio, who thought that the most conspicuous portion of the pons resembled a bridge that connected the two cerebellar hemispheres.

Does the pons control balance?

It also aids in our sense of taste and swallowing. … The pons relays sensory information between the cerebrum and cerebellum. Functions under the control of the cerebellum include fine motor coordination and control, balance, equilibrium, muscle tone, fine motor coordination, and a sense of body position.

What does brain lateralization refer to?

Lateralization of brain function is the view that functions are performed by distinct regions of the brain. … The human brain is split into two hemispheres, right and left. They are both joined together by the corpus callosum, a bundle of nerve fibres which is located in the middle of the brain.

Is the pons in the limbic system?

The archipallium or primitive (“reptilian”) brain, comprising the structures of the brain stem – medulla, pons, cerebellum, mesencephalon, the oldest basal nuclei – the globus pallidus and the olfactory bulbs. The paleopallium or intermediate (“old mammalian”) brain, comprising the structures of the limbic system.

What is the most important part of the brain?

The brain stem is regarded by many as the most important part of the entire brain and nervous system. It is connected to the spine and carries out the task of sending messages to all parts of the body. Every physical movement in the body is carried out in some capacity from the brain stem.

Can you recover from pons damage?

Some side effects of pontine stroke can be restored through rehabilitation. Specifically, loss of sensation, weakness in the limbs, and difficulty with speech and swallowing can be improved.

What can cause damage to the pons?

Damage to the pons most often results from tissue loss due to lack of blood flow (infarct) or bleeding (hemorrhage) – less frequently it can be caused by trauma. An infarct can be caused by several different conditions such as a blood clot (thrombosis) or stroke.

What type of stroke is a pontine stroke?

A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).

Is the pons white or gray matter?

The mesencephalon, metencephalon, and myelencephalon consist of gray and white matter. The gray matter forms the nuclei of the cranial nerves, autonomic nuclei, olivary nuclei, nuclei of the pons and cerebellum, red nuclei, substantia nigra, nuclei of the corpora quadrigemina, and reticular formation.

What are the fluid filled cavities in the brain?

The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).

Who discovered the pons?

The two words Pons Varolii are derived from “Pons” which means bridge in Latin and “Varoli” is the name of the Italian surgeon Costanzo Varolio who discovered this part of the brain between the years 1543 and 1575 (1).

Is known as the little brain?

For the longest time the cerebellum, a dense, fist-size formation located at the base of the brain, never got much respect from neuroscientists. Based on these observations, he concluded the cerebellum was responsible for coordinating movements. …

What is a bridge brain?

It is a thick bundle of nerve fibers that bridges the right and left halves of the brain. It is also the brain’s largest tract of white matter, the neuronal fibers that connect different brain regions.

What is the reptilian brain called?

In MacLean’s triune brain model, the basal ganglia are referred to as the reptilian or primal brain, as this structure is in control of our innate and automatic self-preserving behavior patterns, which ensure our survival and that of our species.

What part of the brain regulates arousal?

The limbic system is important for control of mood, and the nucleus accumbens signal excitement and arousal.

What are the 3 types of the brain?

The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1).

What is lateralization and why is it important?

Lateralization is the differing functions of the left and right hemispheres of the brain. Research over the years has shown that damage to one hemisphere or the other can produce different problems and knowing this can help predict behavior.

Why is lateralization important in the way our brain functions?

Researchers studying the human brain have long maintained that the advantage of having a lateralized brain is increased brain capacity, because lateralization means that neural circuits do not have to be duplicated in each hemisphere. Each hemisphere can have its own specialized circuits and functions.

Who invented brain lateralization?

Broca. One of the first indications of brain function lateralization resulted from the research of French physician Pierre Paul Broca, in 1861. His research involved the male patient nicknamed “Tan”, who suffered a speech deficit (aphasia); “tan” was one of the few words he could articulate, hence his nickname.

What part of the brain controls vision?

The occipital lobe is the back part of the brain that is involved with vision. Temporal lobe.

What part of the brain is responsible for long term memory?

The hippocampus is the catalyst for long-term memory, but the actual memory traces are encoded at various places in the cortex.

What part of the brain controls thirst and hunger?

The hypothalamus controls your pulse, thirst, appetite, sleep patterns, and other processes in your body that happen automatically. The hypothalamus also controls the pituitary gland, which makes the hormones that control growth, metabolism, water and mineral balance, sexual maturity, and response to stress.

Is Pontine the same as pons?

What is pons disease?

Definition. Central pontine myelinolysis (CPM) is a neurological disorder that most frequently occurs after too rapid medical correction of sodium deficiency (hyponatremia). The rapid rise in sodium concentration is accompanied by the movement of small molecules and pulls water from brain cells.

What are pontine lesions?

Neurology. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of the pons.

What is pontine demyelination?

ODS; Central pontine demyelination. Osmotic demyelination syndrome (ODS) is brain cell dysfunction. It is caused by the destruction of the layer (myelin sheath) covering nerve cells in the middle of the brainstem (pons). The central nervous system comprises the brain and spinal cord.
