Electrophysiological analysis of hyperkalemic cardiomyocytes using a multielectrode array system [PDF]

Biophysics and Physicobiology
The action potential of cardiomyocytes is controlled by electrolytes in serum such as Na+, K+ and Ca2+. Hyperkalemia, which refers to an abnormally high concentration of K+ in the blood, can induce lethal arrythmia.

Social Interaction and Cocaine Conditioning in Mice Increase Spontaneous Spike Frequency in the Nucleus Accumbens or Septal Nuclei as Revealed by Multielectrode Array Recordings [PDF]

Pharmacology, 2015
Both cocaine and social interaction place preference conditioning lead to increased neuronal expression of the immediate early gene EGR1 in the nucleus accumbens, a central region of the reward pathway, suggesting that both drug and natural rewards may ...
