Which one is the largest and the main commisure of the brain?
corpus callosum
Split brain experiments the main commissure connecting the cerebral hemispheres is cut describe the results in terms of behavior the can be anticipated in such experiments?
In split-brain experiments, where the main commissure connecting the cerebral hemispheres is cut, individuals may display differences in behavior between the two hemispheres due to limited communication. This can result in isolated functions or responses in each hemisphere, leading to unique behaviors that are not coordinated between the two hemispheres. For example, in a split-brain patient, presenting stimuli to one hemisphere may produce different reactions compared to presenting the same stimuli to the other hemisphere, showcasing the specialization of each hemisphere for certain cognitive processes.
Describe the functions carried out by the lobes in the cerebral hemisphere?
Receives the messages from the Olfactory Lobe and sends them to the main part of the brain
What is each cerebral hemisphere is divided into?
Each cerebral hemisphere is divided into four main lobes: the frontal lobe, responsible for decision-making and movement; the parietal lobe, which processes sensory information; the occipital lobe, dedicated to vision; and the temporal lobe, involved in hearing and memory. Additionally, each hemisphere is associated with specific functions and often exhibits lateralization, where certain cognitive processes are more dominant in one hemisphere than the other.
What arches over diencephalon?
The corpus callosum is the main commissural fiber bundle that arches over the diencephalon, connecting the two cerebral hemispheres.
What commissure is cut during a split brain?
The corpus callosum is the commissure cut during a split-brain procedure, which is a surgical procedure that involves severing the connection between the left and right hemispheres of the brain. This procedure is sometimes performed to alleviate severe forms of epilepsy.
What is the function of cerebral peduncles?
Cerebral peduncles are responsible for connecting the cerebrum to the rest of the brain and spinal cord. They contain fiber tracts that carry motor signals from the cerebral cortex to the spinal cord and brainstem. Additionally, they are involved in coordinating voluntary movement and posture.
Where is location cerebral peduncles?
The cerebral peduncles are located in the midbrain, which is part of the brainstem. They serve as the main motor pathway for nerve impulses traveling from the cerebral cortex to the spinal cord.
What is the two pairs arising from the internal carotid artery?
The internal carotid artery gives rise to two main pairs of arteries: the ophthalmic artery and the middle cerebral artery. The ophthalmic artery supplies the eye and surrounding structures, while the middle cerebral artery is a major supplier of blood to the lateral aspects of the cerebral hemisphere, including areas responsible for motor and sensory functions. Additionally, the anterior cerebral artery, another branch, supplies the medial parts of the frontal lobes and superior medial parietal lobes. Together, these branches play crucial roles in cerebral circulation.
Is Maine in the north east hemisphere?
yes, main is in the northern hemisphere
What is the main culprit damage caused by a cerebral vascular accident?
Glutamate
What are the cerebral hemispheres?
The right and left cerebral hemispheres make up the main part of the brain, called the cerebrum, at the top, front, sides, and part of the back of the brain, and accounts for the majority of the brain's volume.The thin outer layer of the cerebrum is called the cerebral cortex, and is where cognition and long-term memory occur.
