In non-human brains the interthalamic commissure helps keep both hemispheres “in sync” by preventing the animal to have conflicting directional impulses and drives.

Also question is, what is the intermediate mass of the brain?

The intermediate mass is also known as interthalamic adhesion or middle commissure. It is a flattened area of tissues that attaches the two medial surfaces of the thalamus. Thalamus is a small structure positioned above the brain stem between the midbrain and cerebral cortex.

Also to know, where is the third ventricle?

In terms of location, the third ventricle is specifically located in the diencephalon and it is thus referred to as the cavity of the diencephalon. It is a median fossa situated between the right and left thalami.

What does the Massa Intermedia do?

Anatomical terms of neuroanatomy
The interthalamic adhesion (also known as the intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.

What is anterior commissure?

The anterior commissure (also known as the precommissure) is a white matter tract (a bundle of axons) connecting the two temporal lobes of the cerebral hemispheres across the midline, and placed in front of the columns of the fornix.

What is Interthalamic adhesion?

The interthalamic adhesion is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle. The interthalamic adhesion is notably enlarged in patients with the type II Arnold-Chiari malformation.

What is lamina terminalis?

The lamina terminalis is a thin sheet of gray matter and pia mater that attaches to the upper surface of the chiasm and stretches upward to fill the interval between the optic chiasm and the rostrum of the corpus callosum.

What is the fornix of the brain?

The fornix is a C-shaped bundle of fibrous commissural fibers (axons) that extends from the hippocampus to the mammillary bodies of the hypothalamus, the anterior nuclei of the thalamus, and forms an arch over the thalamus. It is located on the medial aspects of the cerebral hemispheres.

Where is the interventricular foramen?

The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. They are located on the underside near the midline of the lateral ventricles, and join the third ventricle where its roof meets its anterior surface.

What does the posterior commissure connect?

The posterior commissure (PC) is a transversely-oriented commissural white matter tract that connects the two cerebral hemispheres along the midline. It is a very important anatomical landmark which is thought to play a role in the visual system, however its functions are still largely unknown.

What does the cerebral aqueduct connect?

Cerebral Aqueduct. The cerebral aqueduct is a narrow channel, 1 to 3 mm in diameter, that connects the third ventricle (the cavity of the diencephalon) with the fourth ventricle (the rhombencephalic cavity).

Why is trauma to the base of the brain more dangerous?

THE BASE OF THE BRAIN IS MORE DANGEROUS THEN TRAUMA TO FRONTAL LOBES BECAUSE IT CONTAINS THE CENTERS MORE VITAL TO LIFE SUCH AS, RESPIRATORY, CARDIAC, AND VASOMOTOR CENTERS. IN "SPLIT BRAIN" EXPERIMENTS, THE MAIN COMMISSURE CONNECTING THE CEREBRAL HEMISPHERES IS CUT.

What is the corpus callosum?

The Corpus Callosum is the part of the mind that allows communication between the two hemispheres of the brain. It is responsible for transmitting neural messages between both the right and left hemispheres.

What is choroid plexus?

Key Points. The choroid plexus (ChP) is a secretory tissue found in each of the brain ventricles, the main function of which is to produce cerebrospinal fluid (CSF).

What is the function of corpora Quadrigemina?

The corpora quadrigemina are reflex centers involving vision and hearing. It consists of groups of nerve cells-grey matter scattered in white matter. It basically connects the forebrain and the hind brain. It has four corpora quadrigemina which are the reflex centres of eye movement and auditory responses.

What is Diencephalon?

The diencephalon is a division of the forebrain (embryonic prosencephalon), and is situated between the telencephalon and the midbrain (embryonic mesencephalon). It consists of structures that are on either side of the third ventricle, including the thalamus, the hypothalamus, the epithalamus and the subthalamus.

What separates the cerebrum from the cerebellum?

The longitudinal fissure separates the two cerebral hemispheres and the transverse fissure is what separates the cerebrum from the cerebellum. Utilizing your knowledge of the brain model, identify the frontal, parietal, temporal, and occipital lobes of the cerebrum.

What is lateral ventricles in the brain?

The lateral ventricles are the largest in the series of four interconnecting fluid-filled cavities within the brain. These cavities and theirs interconnecting channels, constitute the cerebral ventricular system.
