Cerebral blood flow modeling in primate cortex.
We report new results on blood flow modeling over large volumes of cortical gray matter of primate brain. We propose a network method for computing the blood flow, which handles realistic boundary conditions, complex vessel shapes, and complex nonlinear blood rheology. From a detailed comparison of the available models for the blood flow rheology and the phase separation effect, we are able to ...
متن کاملCoupling and robustness of intra-cortical vascular territories
Vascular domains have been described as being coupled to neuronal functional units enabling dynamic blood supply to the cerebral cyto-architecture. Recent experiments have shown that penetrating arterioles of the grey matter are the building blocks for such units. Nevertheless, vascular territories are still poorly known, as the collection and analysis of large three-dimensional micro-vascular ...
متن کاملRole of Local Nerves and Prostaglandins in Regulation of Basal Blood Flow and Hypercapnic Vasodilatation of Cerebral Blood Vessels in the Rabbit
The mechanisms underlying cerebral vasodilatation during hypercapnia are not fully understood. To examine the role of nerves and prostaglandins in the regulation of basal blood flow and in hypercapnia-induced vasodilatation in the cerebral blood vessels of rabbit.Cerebral blood flow was measured by laser Doppler flow-meter in 18 NZW rabbits anesthetized with sodium pentobarbital. Tetrodetoxin ...
متن کاملShort-latency category specific neural responses to human faces in macaque inferotemporal cortex
In this article I would present evidence to show that timing of the flow of neural signals within the ventral visual stream is a crucial part of the neural code for categorization of faces. We recorded the activity of 554 inferotemporal neurons from two macaque monkeys performing a fixation task. More than 1000 object images including human and non-primate animal faces were presented up to 10 t...
متن کاملCEREBRAL BLOOD FLOW REGULATION IN ANESTHETIZED MORPHINE DEPENDENT RATS: THE ROLE OF THE ADENOSINE SYSTEM
Adenosine has many of the characteristics of a regulator of cerebral blood flow and adenosine receptors change in morphine dependency. In this study the changes in adenosine receptors' responsiveness of pial vessels in the hind limb area of the sensory cortex were evaluated in morphine dependent rats (MDR) using the laser Doppler flowmetry technique. Adult male Sprague Dawley rats (250-350 ...
