A sulcus (plural: sulci) is another name for a groove in the cerebral cortex. Each gyrus is surrounded by sulci and together, the gyri and sulci help to increase the surface area of the cerebral cortex and form brain divisions.
What information is processed in the lateral sulcus?
The insula is a deep cortical structure located within the lateral sulcus (see Fig. 1) that serves as a region of integration of information from diverse functional systems related to autonomic regulation, perception, emotion, and cognition (Kurth et al., 2010).
What are the lateral parts of the brain?
The lateral view of the brain shows the three major parts of the brain, cerebrum, cerebellum and brainstem. Observed from the lateral aspect, there are many anatomical landmarks on these structures that carry great functional importance. …
- the frontal lobe.
- the parietal lobe.
- the temporal lobe
- the occipital lobe
Where is the central and lateral sulcus?

What does the lateral sulcus do?
The lateral sulcus divides both the frontal lobe and parietal lobe above from the temporal lobe below. It is in both hemispheres of the brain.
How are sulcus formed?
Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres. By allowing the cortex to invaginate to form sulci and gyri the surface area of the cortex is increased threefold 4.
What does the lateral brain do?
The occipital lobe, only a small part of which is apparent from the lateral surface of the brain, is primarily concerned with vision. In addition to their role in primary and sensory processing, each cortical lobe has characteristic cognitive functions.
Where is the lateral sulcus found?
The lateral sulcus is a deep fissure that is first identified on the inferior surface of the brain close to the anterior perforated substance but becomes most visible on the lateral surface where it separates the frontal and parietal lobes from the temporal lobe.
Which cerebral lobe is deep to the lateral sulcus?
A fifth lobe, the insula or Island of Reil, lies deep within the lateral sulcus.
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 part of brain controls sleep?
The hypothalamus, a peanut-sized structure deep inside the brain, contains groups of nerve cells that act as control centers affecting sleep and arousal.
What are the brain hemispheres?
The cerebrum is divided into two halves: the right and left hemispheres (Fig. 2) They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body.
What are brain sulci?
Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres. … Some may not be present in a number of individuals and others deep enough to produce elevations on the surface of the ventricles (e.g. collateral sulcus, calcarine sulcus/calcar avis) 4.
Where is sulci located in the brain?
cerebral cortex sulci) is a depression or groove in the cerebral cortex. It surrounds a gyrus (pl. gyri), creating the characteristic folded appearance of the brain in humans and other mammals.
What is the center of your brain called?
The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.
What happens if the Sylvian fissure is damaged?
Damage above the Sylvian fissure, in the parietal and frontal lobes, tended to cause speech production deficits; damage below the Sylvian fissure, in the temporal lobe, tended to cause speech recognition deficits.
Why do we have convolutions?
The cerebral cortex of the human brain is highly convoluted, meaning it has many folds and creases. These convolutions allow a large surface area of brain to fit inside our skulls. Because of this brain shape, our brains can have billions of neurons and we can still have relatively small heads!
What does the frontal lobe do?
The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one’s responses in order to achieve a goal.
What is sulcus in heart?
Anatomical terminology. The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart that separates the atria from the ventricles.
What is the complete sulcus?
The calcarine sulcus (or calcarine fissure) is an anatomical landmark located at the caudal end of the medial surface of the brain of humans and other primates. Its name comes from the Latin calcar meaning spur. It is very deep and known as a complete sulcus.
Why does brain have sulci and gyri?
Gyri and Sulci Functions Brain gyri and sulci serve two very important functions: They increase the surface area of the cerebral cortex and they form brain divisions. Increasing the surface area of the brain allows more neurons to be packed into the cortex so that it can process more information.
What is the right brain responsible for?
The right side of your brain is in charge of visual awareness, imagination, emotions, spatial abilities, face recognition, music awareness, 3D forms, interpreting social cues, and left-hand control.
What are the 4 lobes of brain?
The cerebral cortex is divided lengthways into two cerebral hemispheres connected by the corpus callosum. Traditionally, each of the hemispheres has been divided into four lobes: frontal, parietal, temporal and occipital.
Which side of the brain controls memory?
right Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving.
What artery runs in the lateral sulcus?
From its origin lateral to the anterior perforated substance, the fissure courses medially to form the stem of the lateral fissure, also known as the Sylvian cistern, into which passes the middle cerebral artery and its major branches.
In what way is the location of the central sulcus and lateral sulcus important for brain anatomy?
Lateral aspect of the brain The central sulcus is one of the most important landmarks in the human brain for clinicians and neuroscientists because it precisely divides the somatic sensory cortex of the parietal lobe from the motor cortex of the frontal lobe.
Which cerebral lobe is deep to the lateral sulcus quizlet?
In each hemisphere of the mammalian brain the insular cortex (often called insula, insulary cortex or insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes).
What are the 4 lobes of the brain and their function?
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
Where are the 4 lobes of the brain located?
The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe is involved in reasoning, motor control, emotion, and language.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
