The reactivity of the somesthetic S1 cortex during sleep and waking in the rat

Brain Research Bulletin
C ArnaudC Gottesmann


The reactivity of the somesthetic S1 cortex was studied in the rat, in the course of the seven principle stages of the sleep-waking cycle, in terms of the variation in amplitude of positive wave 4 of the evoked potential induced by stimulation of the thalamocortical radiations. The amplitude of positive wave 4 is minimal during waking with theta (attentive and/or active). It increases in the course of waking without theta, to reach its maximum during the stage of sleep with slow waves. The amplitude decreases with the deepening of slow sleep (spindles, intermediate stage) to a level near to waking without theta, during rapid sleep. No significant difference is observed during periods of eye movements bursts. The variability of the amplitude of intra-state responses is lowest in the phases of waking and paradoxical sleep. The recovery cycle of the S1 cortex responses is long (several hundreds of milliseconds). The rate of recovery is inversely proportional to the amplitude of the response to the conditioning stimulus. It is therefore higher during waking and rapid sleep than during the different stages of slow sleep. These results are integrated in the neurophysiological data of sleep in the rat.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
