Glossary

Dyskinetic = abnormal movement.  Cerebral palsy characterized by abnormal movements that can be slow, writhing or fast and jerky.  Types of dyskinetic CP are athetoid CP, chorea CP, and dystonic CP.

Referring to a failure of part of the midline of an embryo to fuse. Most commonly this term is seen in discussions about failure of midline structures of the spinal and/or spinal cord to fuse (i.e., spinal dysrahism), as in spina bifida.

A movement disorder consisting of involuntary muscle contractions that result in slow, repetitive movements and/or postures.

External Carotid Artery

Electrocardiogram, aka EKG. A recording of the electrical of the heart.

Electrocorticography – the recording of electroencephalography activity during a surgery. This is typically done in the setting of a need for identification of abnormal brain activity such as seen with seizures.

A revascularization technique used to treat cerebral ischemia due to Moyamoya Disease. The technique consists of dissecting a segment of the temporalis muscle with the the superficial temporal artery attached  without disturbing its vascular flow. The muscle is then laid down onto the exposed cortical surface after performing a craniotomy and dural opening. It can be held in contact by sewing the muscle to the cut edges of dura prior to closing the surgical wound.

Encephaloduroarteriosynangiosis – A revascularization technique used to treat cerebral ischemia due to Moyamoya Disease. The technique consists of dissecting superficial temporal artery free from surround scalp with a cuff of galea for a length of several centimeters without disturbing its vascular flow. The artery is then laid down onto the exposed cortical surface after performing a craniotomy and dural opening. It is held in contact by sewing the galeal cuff to the cut edges of dura prior to closing the surgical wound.

Electroencephalograph – The recording of the electrical activity emitted by the brain’s neurons.

A gene involved in production of the Ephrin B1 protein, a protein involved in the development of cell-to-cell adhesion and communication.  It plays a critical role in evolving the shaping of tissues and organs during embryonic development.
