814-557: The description of the tentorial notch (the so-called "Pacchioni's oval foramen"), the observation that dural adherence to the inner table is variable in different areas, and especially the discovery of arachnoid granulations. In 1705, Pacchioni dedicated to Professor Luca Schrok (a German colleague from Augsburg) the Dissertatio Epistolaris de Glandulis Conglobatis Durae Meningis Hurnanae, indeque Ortis Lymphaticis and Piam Meningem produclis.

851-453: The discussion of their doctoral thesis). Moreover, Pacchioni exhibited a remarkable attention to scientific progress beyond Italy's borders as shown by the frequent quotation of foreign authors in his works (Willis and Vieussens among others).

999-546: The function of an organ was merely based on its mechanical activity. Therefore, he believed that dura mater was a special kind of membranous muscle ("musculus suigeneris membranaceus"), comparable to cardiac muscle, made up of several layers of fibers and arranged in three bellies and four tendons; its contractions served to squeeze the glands which, in Malpighi's opinion, constituted the cerebral cortex, pushing their secretion along nerve roots? Among Pacchioni's findings, we recall

1036-513: The latter was known to be a protegé of Pope Innocenzo XII. The year 1705 was a special time in Pacchioni's life: he was appointed head physician at the ancient Ospedaledi S.

He was fellow of several prestigious academies such as

1073-490: The less demanding charge of head physician at his favorite Ospedale della Consolazione, where he worked until retirement. He was struck by an undetermined disease of the central nervous system (perhaps a tumor or intracranial hematoma) that caused seizures, a right hemiparesis, and progressive mental deterioration. He was attended to by his most trusted colleagues and his old master Vallisneri. Pacchioni died in Rome at 62 years of age. Despite his extreme versatility, Pacchioni

1110-451: The light of present knowledge, new observations seem "to do justice" to Antonio Pacchioni. In a recent study, Go, et al., ~ using enzyme ultracnytochemistry, detected Na+/K + adenosine triphosphatase activity on cap cells of arachnoid villi; they proposed that this biochemical mechanism could contribute to CSF absorption. This assumption implies a "'secretory" component in CSF absorption along with

1147-526: The massive Rocca Pia to control the always restive population, and as a symbol of the permanence of papal temporal power here. From the sixteenth century the city saw further construction of villas. The most famous of these is the Villa d'Este , a World Heritage Site , whose construction was started in 1550 by Pirro Ligorio for Cardinal Ippolito II d'Este and which was richly decorated with an ambitious program of frescoes by painters of late Roman Mannerism, such Girolamo Muziano, Livio Agresti (a member of

The present Piazza del Duomo occupies the Roman forum. In 547, in the course of the Gothic War , the city was fortified by

1295-421: The sinus. Numerous thin filaments, which he thought were lymphatic vessels, seemed to bloom from the "glandulae," running toward the pia on one side and penetrating dural layers on the other. Therefore, he concluded that his "glandulae" (glands) had the function of secreting lymph to lubricate the sliding movements between brain and meninges during contractions. Although these speculations appear grossly incorrect in

1332-460: The slaughter at Thebes, Greece . Catillus and his three sons Tiburtus, Coras, and Catillus drove out the Siculi from the Aniene plateau and founded a city they named Tibur in honor of Tiburtus.

Pacchioni's most important works particularly concerned
