Corpus callosotomy
A surgical procedure in which the corpus callosum, the bridge between the two hemispheres of the brain, is severed. This interrupts the flow of information between the two hemispheres. Commissurectomy was previously performed mainly for the purpose of controlling epileptic seizures.

Confabulation
Confabulation refers to a memory or explanation that the person concerned is completely convinced is true, but which is objectively false. There is no conscious intent to deceive behind this. The cause is usually medical, such as damage to the orbitofrontal or other frontal brain areas, amnestic syndrome (e.g., Korsakoff's syndrome), traumatic brain injury, or dementia.

Convergence
Convergence of neurons occurs when several neurons are connected synaptically to a single transmitting neuron. In the eye, for example, information received by up to 130 receptors is transmitted to only one neuron in the retina. The opposite is divergence, when one neuron transmits signals to several other neurons.

Basket cell
Basket cells are interneurons in the cerebellum and hippocampus. In the cerebellum, they are excited by parallel fibers and in turn inhibit Purkinje cells.

Granule cell
Relatively small nerve cells found in the cortex (cerebral cortex), hippocampus, olfactory bulb, and cerebellum. In the cortex, they are primarily located in layer IV and are predominantly excitatory. In the cortex of the cerebellum, they constitute 99% of the cells and form the parallel fibers.
