25. Lethal femoral-facial syndrome: a case with unusual manifestations.
The femoral-facial syndrome is a very rare syndrome of uncertain inheritance comprising hypoplastic femora, microretrognathia, and a peculiar facies. We report an additional observation detected by ultrasound at 25 weeks and diagnosed at birth. In addition to the malformations usually described in this syndrome, there were heterotopias of the brain, partial

26. Ectopic midline spinal ganglion in diastematomyelia: a study of its connections.
The connections of an ectopic midline spinal ganglion associated with an asymptomatic sacral diastematomyelia were studied. The ganglion was intercalated in the ventral root of one hemicord and sent its efferents to the dorsal root of the other hemicord. The afferents joined the anterior root to form a midline intradural spinal nerve in the cauda equina. Isl

27. Localised neuronal migration disorder and intractable epilepsy: a prenatal vascular aetiology.
Localised neuronal heterotopias are an increasingly recognised cause of intractable focal epilepsies. The aetiology of these circumscribed disorders of neuronal migration is often unknown although in some instances proximity to areas of prenatal infarction suggests that severe ischaemia was responsible. A patient is described with intractable complex partial

28. Neuronal migration disorders: Heterotopic neocortical neurons in CA1 provide a bridge between the hippocampus and the neocortex
Neuronal migration disorders have been involved in various pathologies, including epilepsy, but the properties of the neural networks underlying disorders have not been determined. In the present study, patch clamp recordings were made from intrahippocampal heterotopic as well as from neocortical and hippocampal neurons from brain slices of rats with prenata
