- More partial seizures on one side of the brain.
- Speech problems, including trouble producing speech (apraxia) and trouble speaking and comprehending (aphasia).
- Stroke.

Why is split-brain important?
Sperry severed the corpus callosum in cats and monkeys to study the function of each side of the brain. He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain. The split-brain enabled animals to memorize double the information .
How is split brain syndrome treated?
Corpus callosotomy is surgery to treat epilepsy seizures when antiseizure medications don’t help. The procedure involves cutting a band of fibers (the corpus callosum) in the brain. Afterward, the nerves can’t send seizure signals between the brain’s two halves.
What is split brain syndrome in RAC?
Split Brain Syndrome, In a Oracle RAC environment all the instances/servers communicate with each other using high-speed interconnects on the private network . This private network interface or interconnect are redundant and are only used for inter-instance oracle data block transfers.
Who studied the effects of split brain surgery on cognitive functioning?
In the 1950s and 1960s, Roger Sperry performed experiments on cats, monkeys, and humans to study functional differences between the two hemispheres of the brain in the United States.
How does the corpus callosum affect behavior?
Individuals with a disorder of the corpus callosum typically have delays in attaining developmental milestones such as walking, talking, or reading; challenges with social interactions ; clumsiness and poor motor coordination, particularly on skills that require coordination of left and right hands and feet (such as ...
What happens if corpus callosum is damaged?

Where would a surgeon split the brain?
A corpus callosotomy is an operation that severs (cuts) the corpus callosum , interrupting the spread of seizures from hemisphere to hemisphere. Seizures generally do not completely stop after this procedure (they continue on the side of the brain in which they originate).
What is OCR file in Oracle?
Oracle Cluster Registry (OCR) The OCR contains cluster and database configuration information for RAC and Cluster Ready Services (CRS) such as the cluster node list, and cluster database instances to node mapping, and CRS application resource profiles. The OCR is a shared file located in a cluster file system.
What is node eviction in RAC?
A node eviction is done when a heartbeat indicates that a node is not responding , and the evicted node is re-started so that it can continue to partiipate in the cluster. ... Reason for RAC node evictions. There are many reasons for a RAC node eviction.
