Large and fast human pyramidal neurons associate with intelligence

eLife, 2018
It is generally assumed that human intelligence relies on efficient processing by neurons in our brain. Although grey matter thickness and activity of temporal and frontal cortical areas correlate with IQ scores, no direct evidence exists that links ...

Modulation of neural cell membrane conductance by the herbal anxiolytic and antiepileptic drug aswal [PDF]

, 2000
To evaluate the effects of aswal on ionic fluxes and neuronal excitation, we performed extracellular and whole cell patch clamp recordings on CA1 pyramidal neurons of guinea pigs and Long-Evans rats.

Intraoperative Microelectrode Recordings in Substantia Nigra Pars Reticulata in Anesthetized Rats

Frontiers in Neuroscience, 2020
The Substantia Nigra pars reticulata (SNr) is a promising target for deep brain stimulation (DBS) to treat the gait and postural disturbances in Parkinson’s disease (PD).

Similarities between action potentials and acoustic pulses in a van der Waals fluid [PDF]

, 2018
An action potential is typically described as a purely electrical change that propagates along the membrane of excitable cells. However, recent experiments have demonstrated that non-linear acoustic pulses that propagate along lipid interfaces and ...

Modulation of Functional Connectivity Between Dopamine Neurons of the Rat Ventral Tegmental Area in vitro

Frontiers in Integrative Neuroscience, 2019
Micro Electrode Arrays were used to simultaneously record spontaneous extracellular action potentials from 10 to 30 dopamine neurons in acute brain slices from the lateral Ventral Tegmental Area (VTA) of the rat.

Single fibre action potentials in skeletal muscle related to recording distances [PDF]

, 1994
Single muscle fibre action potentials (SFAPs) are considered to be functions of a bioelectrical source and electrical conductivity parameters of the medium.

Parametric analysis of the ionic concentrations effects in the behavior of the sinoatrial node

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
A sensibility study on the effect of ionic concentrations in the behavior of the sinoatrial node was carried out. The study was based on the model proposed by H. Zhang, A. V. Holden and M.R. Boyett.

Effects of sugammadex and rocuronium on electro-mechanical activity of cardiac myocytes [PDF]

Korean Journal of Anesthesiology
Background Sugammadex reverses the effects of steroidal neuromuscular-blocking agents, such as rocuronium, by encapsulating these agents. Its cardiovascular adverse effects include QTc prolongation, hypotension, bradycardia, atrioventricular block ...

A brief exposure to toluene vapor alters the intrinsic excitability of D2 medium spiny neurons in the rat ventral striatum

Frontiers in Neuroscience, 2023
Although volatile organic solvents such as toluene are used for commercial and industrial uses, they are often voluntarily inhaled for their intoxicating and euphoric effects.

Presynaptic actions of 4-Aminopyridine and γ-aminobutyric acid on rat sympathetic ganglia in vitro [PDF]

, 1980
Responses to bath-applications of 4-aminopyridine (4-AP) and -aminobutyric acid (GABA) were recorded intracellularly from neurones in the rat isolated superior cervical ganglion.
