What is the cingulate sulcus?
sulcus found on the medial wall of the cerebral hemispheres. The cingulate sulcus is adjacent to the cingulate gyrus, also known as the cingulate cortex. It separates the cingulate cortex and limbic lobe from the frontal and parietal lobes.
What happens if corpus callosum is damaged?
Lesions of any part of the corpus callosum might lead to loss of contact between bilateral hemispheres that cause mental disorders, pseudobulbar palsy, speech and movement ataxia.
What is the function of corpus callosum in the brain?
The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other.
Can you live without a corpus callosum?
Many people with agenesis of the corpus callosum lead healthy lives. However, it can also lead to medical problems, such as seizures, which require medical intervention.
Where is the cingulate sulcus located?
frontal lobes
The cingulate sulcus is situated directly superior to the cingulate gyrus, which is formed by the medial surface of the frontal lobes that is directly above the corpus callosum.
Where is the precentral sulcus?
frontal lobe
The precentral sulcus is one of the major sulci of the frontal lobe, running in front of and parallel to the central sulcus, separated from it by the precentral gyrus.
What are the symptoms of a damaged corpus callosum?
Symptoms of Corpus Callosum Injury
- Dysarthria, or slurred speech.
- Dysphagia, or difficulty swallowing.
- Dysphonia, or spasms in the vocal cords that cause changes in your voice.
- Emotional lability, or exaggerated mood swings.
How can I improve my corpus callosum?
Activities to Build the Corpus Callosum
- Crawling Races. Have crawling races with your child or baby to encourage crawling and bilateral integration for longer periods of time.
- Toy Reach.
- Flashlight Tag.
- Blow Bubbles.
- Practice Hand Dominance.
- Soccer Kicks.

What is hippocampal sulcus?
The hippocampal sulcus is the inferior lateral extension of the transverse fissure (of Bichat), which in turn communicates with the ambient cistern. It is a shallow groove on the medial surface of the hippocampus, between the dentate gyrus and subiculum, inferior to the fimbria and fimbriodentate sulcus 1.
What does precentral sulcus do?
An important functional area of the frontal lobe is the precentral gyrus, which is located rostral to the central sulcus. The precentral gyrus is called the somato-motor cortex because it controls volitional movements of the contralateral side of the body.
Is the callosal sulcus in the lateral ventricles?
Callosal sulcus is shown in red. The corpus callosum forms the floor of the longitudinal fissure that separates the two cerebral hemispheres. It also forms part of the roof of the lateral ventricles. The corpus callosum has four main parts; individual nerve tracts that connect different parts of the hemispheres.
Where is the corpus callosum located in the brain?
The corpus callosum is only found in placental mammals. It spans part of the longitudinal fissure, connecting the left and right cerebral hemispheres, enabling communication between them. It is the largest white matter structure in the human brain, about ten centimetres in length and consisting of 200–300 million axonal projections.
Where is the callosal sulcus located in the monkey?
Although there is a boundary along the corpus callosum, this is technically not a sulcus but a white matter/grey matter junction. Thus, the cas is mainly in the PCG in the monkey. In contrast, the human has a well formed cas at anterior and midcingulate levels and forms a shallow invagination for the ventral bank of the CG.
Where are the retrosplenial areas of the callosal sulcus?
The retrosplenial areas do not appear on the surface of the posterior cingulate gyrus but are in the depths of the callosal sulcus and continue in the dorsal bank of the calcarme sulcus. Most importantly, the retrosplenial and posterior cingulate cortices have no documented role in affect or motivation.
