Single-neuron discharge properties and network activity in dissociated cultures of neocortex.

Cultures of neurons from rat neocortex exhibit spontaneous, temporally patterned, network activity. Such a distributed activity in vitro constitutes a possible framework for combining theoretical and experimental approaches, linking the single-neuron discharge properties to network phenomena. In this work, we addressed the issue of closing the loop, from the identification of the single-cell di...

Rhythm Generation in Spinal Cultures: Is It the Neuron or the Network?

The impact of input fluctuations on the frequency-current relationships of layer 5 pyramidal neurons in the rat medial prefrontal cortex.

The role of irregular cortical firing in neuronal computation is still debated, and it is unclear how signals carried by fluctuating synaptic potentials are decoded by downstream neurons. We examined in vitro frequency versus current (f-I) relationships of layer 5 (L5) pyramidal cells of the rat medial prefrontal cortex (mPFC) using fluctuating stimuli. Studies in the somatosensory cortex show ...

Modulation of intrinsic spiking in spinal cord neurons.

The vertebrate spinal cord is equipped with a number of neuronal networks that underlie repetitive patterns of behavior as locomotion. Activity in such networks is mediated not only by intrinsic cellular properties but also by synaptic coupling. In this study, we focused on the modulation of the intrinsic activity by 5-hydroxytryptamine (5-HT, serotonin) and the cholinergic agonist muscarine in...

بررسی تاثیر مصرف جوانهی گندم بر پروفایل لیپید

diseases and emphasis on using nondrug treatments, this study was performed to assess the effect of wheat germ on lipid profile reduction among hyperlipidemia and normolipidomia students. Materials and Methods: 108 volunteer students in the age range of 21.33±2.15 years old (74 normolipidemics, 34 hyperlipidemics) were entered to the study. In addition to their typical diet, these students were...
