introduction: antibiotic supplements are regularly used in neuronal culture media to control contamination however, they can interfere with the neuronal excitability and affect electrophysiological properties. therefore, in this study, the effect of penicillin/streptomycin supplements on the spontaneous electrophysiological activity of hippocampal pyramidal neurons was examined. methods: electr...

Background and purpose: Methamphetamine (METH) is one of the most powerful drugs that leads to many cognitive and behavioral side effects such as anxiety. On the other hand, studies have shown that ovarian hormones such as estrogen and progesterone have neuroprotective effects on a wide range of cognitive and behavioral disorders. The aim of this study was to investigate the role of estrogen an...

epilepsy is accompanied with a strong change in neuronal activity not only in excitatory (glutamatergic) and inhibitory (gabaergic) neurotransmission, but also in neuromodulatory agents. dopaminergic system, as an important neuromodulatory system of the brain, has significant effect on neuronal excitability. in addition, this system undergoes many changes in epileptic brain. understanding the e...

this study has examined the functional importance of nucleus accumbens (nac)-ventral tegmental area (vta) interactions. as it is known, this interaction is important in associative reward processes. under urethane anesthesia, extracellular single unit recordings of the shell sub-region of the nucleus accumbens (nacsh) neurons were employed to determine the functional contributions of the vta to...

New probes are letting neuroscientists record neuronal activity over larger areas and longer time periods

It is an Intensive 1-day course for introducing utilizing transcranial direct current stimulation (tDCS) in an applied format. This technique is a noninvasive brain stimulation that uses direct electrical currents over the head to stimulate specific parts of the brain which modulates neuronal activity. It has strong potentiality in the field of medical and neuroscientific research. Anodal stimu...

Adrenergic receptors have an important role in neural excitability and synaptic plasticity. Despite a lot of studies on these receptors, their exact role in brain disorders accompanied with hyperexcitability has not been determined. There are also controversies on their role in synaptic plasticity. In this review article, the important studies done in this regard have been reviewed to achieve a...
