The internal capsule is a white matter structure situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the basal ganglia, separating the caudate nucleus and the thalamus from the putamen and the globus pallidus. The internal capsule contains both ascending and descending axons, going to and coming from the cerebral cortex. It also separates the caudate nucleus and the putamen in the dorsal striatum, a brain region involved in motor and reward pathways.

Hinging breast implant
A hinging breast implant capable a being variably sized and that includes an exterior shell and an inner bladder is described. The exterior shell is typically a bellows having a plurality of pleats so that the outer size of the implant is variable so that different sizes and shapes can be obtained. The rear of the housing closest to the patient's interior is typically shaped in order to conform to the patient's rib cage and internal connective tissues. Conversely, the front of the housing is shaped to naturally conform to the outer shape of the patient. The inner bladder can be filled with a suitable filling material, liquid, gas or solid. As the bladder is filled, the exterior shell expands in a manner that creates a lifting effect and a ballooning effect. An appendage, used to fill the bladder external to the patient, is connected to both the exterior shell and the inner bladder.
