ABSTRACT
Modern humans appeared in Europe by at least 45,000 years ago1-5, but the extent of their interactions with Neanderthals, who disappeared by about 40,000 years ago6, and their relationship to the broader expansion of modern humans outside Africa are poorly understood. Here we present genome-wide data from three individuals dated to between 45,930 and 42,580 years ago from Bacho Kiro Cave, Bulgaria1,2. They are the earliest Late Pleistocene modern humans known to have been recovered in Europe so far, and were found in association with an Initial Upper Palaeolithic artefact assemblage. Unlike two previously studied individuals of similar ages from Romania7 and Siberia8 who did not contribute detectably to later populations, these individuals are more closely related to present-day and ancient populations in East Asia and the Americas than to later west Eurasian populations. This indicates that they belonged to a modern human migration into Europe that was not previously known from the genetic record, and provides evidence that there was at least some continuity between the earliest modern humans in Europe and later people in Eurasia. Moreover, we find that all three individuals had Neanderthal ancestors a few generations back in their family history, confirming that the first European modern humans mixed with Neanderthals and suggesting that such mixing could have been common.

PURPOSE: We attempted to identify cultural aspects of epilepsy among the Roma community in Bulgaria by elucidating cultural beliefs, traditional treatments, and potential markers of stigma. METHODS: We established representative discussion groups among five distinct Roma subgroups (Lom, Kalderas, Thracian Tinsmiths (Tinkers), Kyustendil Xoroxane and Kopanari) from different Bulgarian regions. Data about local beliefs and treatment strategies were gathered. RESULTS: Most people were familiar with convulsions but non-convulsive focal seizures were seen not as epileptic but mainly as a "mental problem". Beliefs about putative etiologies for epilepsy were not uniform as some considered environmental and external factors such as high environmental temperatures, electric shocks, loud music, and fever as causes of seizures while others listed bad experiences, stress, trauma, and fear as possible causes. Epilepsy was seen by some as a divine punishment or resulting from black magic. Most considered epilepsy shameful and an obstacle to children attending school. Despite local differences, there was a uniform belief that epilepsy is incurable by Western medicine and people usually resort to traditional healers. A variety of rituals performed by local healers to treat epilepsy were described. DISCUSSION: Misconceptions about epilepsy may contribute to stigmatization in this population; this may in turn contribute to a high treatment gap in this group. As a result, the majority of Roma children with epilepsy are likely to leave school early, are greatly limited in their choice of spouse (particularly girls), and marriages often occur between people with epilepsy or those with a family history of epilepsy.

Paleoneurosurgery represents a comparatively new developing direction of neurosurgery dealing with archaeological skull and spine finds and studying their neurosurgical aspects. Artificial skull deformation, as a bone artifact, naturally has been one of the main paleoneurosurgical research topics. Traditionally, the relevant neurosurgical literature has analyzed in detail the intentional skull deformations in South America's tribes. However, little is known about the artificial skull deformations of the Proto-Bulgarians, and what information exists is mostly due to anthropological studies. The Proto-Bulgarians originated from Central Asia, and distributed their skull deformation ritual on the Balkan Peninsula by their migration and domination. Proto-Bulgarian artificial skull deformation was an erect or oblique form of the anular type, and was achieved by 1 or 2 pressure bandages that were tightened around a newborn's head for a sufficiently long period. The intentional skull deformation in Proto-Bulgarians was not associated with neurological deficits and/or mental retardation. No indirect signs of chronic elevated intracranial pressure were found on the 3D CT reconstruction of the artificially deformed skulls.
