MODULATION OF DEFENSIVE REFLEX CONDITIONING IN SNAILS BY SEROTONIN
Frontiers in Behavioral Neuroscience, 2015 We studied the role of serotonin in the mechanisms of learning in terrestrial snails. To produce a serotonin deficit, the neurotoxic analogues of serotonin, 5,6- or 5,7-dihydroxytryptamine (5,6/5,7-DHT) were used.

Modeling Interference-Free Neuron Spikes with Optogenetic Stimulation [PDF]
, 2019 This paper predicts the ability to externally control the firing times of a cortical neuron whose behavior follows the Izhikevich neuron model. The Izhikevich neuron model provides an efficient and biologically plausible method to track a cortical neuron'

A low-voltage activated, transient calcium current is responsible for the time-dependent depolarizing inward rectification of rat neocortical neurons in vitro [PDF]
, 1987 Intracellular recordings were obtained from rat neocortical neurons in vitro. The current-voltage-relationship of the neuronal membrane was investigated using current- and single-electrode-voltage-clamp techniques.

Ion channels to inactivate neurons in Drosophila
Frontiers in Molecular Neuroscience, 2009 Ion channels are the determinants of excitability; therefore, manipulation of their levels and properties provides an opportunity for the investigator to modulate neuronal and circuit function.

Joule heating involving ion currents through channel proteins
Biophysics and Physicobiology, 2023 Ion currents associated with channel proteins in the presence of membrane potential are ubiquitous in cellular and organelle membranes. When an ion current occurs through a channel protein, Joule heating should occur. However, this Joule heating seems to

Stochastic Dynamics of Electrical Membrane with Voltage-Dependent Ion Channel Fluctuations
, 2014 Brownian ratchet like stochastic theory for the electrochemical membrane system of Hodgkin-Huxley (HH) is developed. The system is characterized by a continuous variable $Q_m(t)$, representing mobile membrane charge density, and a discrete variable $K_t$
