TNO Biomedical Instrumentation (author), van Lieshout, J.J. (author), Pott, F. (author), Madsen, P.L. (author), van Goudoever, J. (author), Secher, N.H. (author)Background and Purpose - When standing up causes dizziness, tensing of the leg muscles may alleviate the symptoms. We tested the hypothesis that leg tensing improves orthostatic tolerance via enhanced cerebral perfusion and oxygenation. Methods - In 10 healthy young adults, the effects of leg tensing on transcranial Doppler-determined middle...article 2001

Neurophysiol., Westeinde Hosp., The Hague, Netherlands Medisch Biologisch Laboratorium TNO (author)The local EEG, the local cerebral blood flow (lCBF), and the flow in the distal stump of the occluded middle cerebral artery were simultaneously recorded in 28 acute experiments in cats. Nembutal anesthesia was used eleven times, and Halothane anaesthesia 17 times. The recordings were made via platinum electrodes: 12 in the ischaemic hemisphere,...article 1982

Tulleken, C.A.F. (author), van Dieren, A. (author), Mollevanger, W.J. (author), van Eijck, P. (author), Inst. Med. Phys., TNO, Utrecht, Netherlands (author)In a group of 21 cats, the middle cerebral artery pressure (MCAP) was recorded by means of a catheter introduced into the artery at its origin, just distal to the occlusion. The effects of hypertension, hypercapnia, and hypocapnia were studied. In a group of five cats, both middle cerebral arteries (MCA) were catheterized and the pressure was...article 1978
