Neutral red as a hydrophobic probe for monitoring neuronal activity

Journal of Neuroscience Methods, 2000
Neutral red fluorescence has been used to monitor neuronal activity. Local changes in either pH or hydrophobicity are reported to increase neutral red fluorescence, but the mechanisms underlying the increases remain unclear. In this study, the pH-dependent fluorescence changes in the basic and acidic forms of neutral red preloaded in rat cerebellar ...

Paralelización de una red neuronal

, 2021
El entrenamiento de una red neuronal es altamente costoso cuando hablamos de los recursos de un sistema computacional. En este documento se recoge el desarrollo seguido para conseguir una reducción del tiempo en dicha fase. Este objetivo se ha logrado paralelizando este proceso gracias al uso de computación de alto rendimiento o high-performance ...

Afterhyperpolarization in neurones of the red nucleus

Experimental Brain Research, 1984
Afterhyperpolarization (AHP) following single or short trains of spikes in rubrospinal neurones (RN neurones) of the cat has been studied with intracellular recording techniques. The AHP amplitude was potential dependent; it increased with depolarization and decreased with hyperpolarization and had an extrapolated reversal potential about 20 mV below ...

‘Disfacilitation’ of red nucleus neurones

Experientia, 1965
Dans les neurones du noyau rouge, il a ete demontre par l'enregistrement intracellulaire que les potentiels hyperpolarisants de longue duree sont produits par la stimulation de la region du noyau interpose et du cortex cerebelleux. En changeant le potentiel de membrane de la cellule, l'amplitude de l'hyperpolarisation diminue ou augmente parallelement ...

Electrical constants of neurons of the red nucleus

Experimental Brain Research, 1975
Membrane electrical constants have been studied in neurons of the red nucleus (RN) of the cat which were identified antidromically from the spinal cord. For each cell, the input resistance was determined from the membrane potential changes to current steps and was found to be 2.5+/-0.9 Momega in twenty five RN cells studied.

The organization of projection neurons in the opossum red nucleus

Brain Research, 1974
Abstract The opossum red nucleus is populated by neurons encompassing a considerable size range. The largest neurons (giant neurons, 45–70 μm) are restricted to its caudal, medial third, whereas those in the large-medium category (25–40 μm) are located throughout the nucleus. The smallest neurons (less than 20 μm) are relatively achromatic and few in

The mode of cerebral activation of red nucleus neurones

Experientia, 1966
Elektrische Reizung des sensorimotorischen Kortex ruft monosynaptische EPSPs, in den grossen Zellen des N. ruber der Katze hervor (RNZellen). Die kortikalen Punkte, von denen EPSPs hervorgerufen werden konnen, sind somatotopisch so angeordnet, dass sie mit der histologischen Projektion der kortikorubralen Fasern ubereinstimmen.

Improving RED by a Neuron Controller

2007
In this paper, we propose a novel active queue management (AQM) algorithm called Neuron Control RED (NC-RED) that overcomes the drawbacks of the original RED. NC-RED uses a neuron controller to adaptively adjust the maximum drop probability to stabilize the average queue length around the target queue length.
