Relative sizes of cortical visual areas in marmosets: functional and phylogenetic implications.

Visual areas V1, V2 and MT (V5) were identified through myeloarchitectonic criteria and their sizes estimated in a flattened map of caudal cerebral cortex in the marmoset Callithrix penicillata. The ratio MT/V1 in this species is similar to values reported for other species of primates, but the ratio V2/V1 in Callithrix penicillata is smaller than that in macaques and larger than that in Aotus. The possible implications of these results are discussed.

A previously undescribed condition: tricho-odonto-onycho-dermal syndrome. A review of the tricho-odonto-onychial subgroup of ectodermal dysplasias.

An apparently hitherto undescribed ectodermal dysplasia/malformation syndrome is presented. The patient, the last son in an outbred sibship of four males, presents scalp hypotrichosis, aplasia cutis congenita of the scalp, dental abnormalities, onychodyplasia, dry skin with hypochromic and atrophic (poikiloderma-like) spots with vicarious (marginal) hyperchromia, unusual facies, asymmetrical skull, absent right nipple, irregular areolae, palmar keratosis, dermatoglyphic alterations, syndactyly, clinodactyly, phalangeal aplasias and hypoplasias, right leukoma, abnormal EEG, and other findings. The aetiology is unknown. A review of seventeen ectodermal dysplasias is presented for different diagnosis.

A syndrome of hypohidrotic ectodermal dysplasia with normal teeth, peculiar facies, pigmentary disturbances, psychomotor and growth retardation, bilateral nuclear cataract, and other signs.

This paper describes a 7-year-old girl with trichodysplasia, normal teeth, onychogryposis, hypohidrosis, psychomotor and growth retardation, dry and warm skin with follicular hyperkeratosis, pigmentary disturbances (hyper- and hypochromic spots), bilateral nuclear cataract, dermatoglyphic anomalies, and other signs. This condition is considered a new form of ectodermal dysplasia.
