Acetylcholine receptor

An acetylcholine receptor (abbreviated AChR) is an integral membrane protein that responds to the binding of acetylcholine, a neurotransmitter.

Cav1.1

Cav1.1 also known as the calcium channel, voltage-dependent, L type, alpha 1S subunit, (CACNA1S), is a protein which in humans is encoded by the CACNA1S gene.

Excitatory postsynaptic potential

In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential.

Histrionicotoxins

Histrionicotoxins are a group of related toxins found in the skin of poison frogs from the family Dendrobatidae, notably Oophaga histrionica (formerly Dendrobates histrionicus), which are native to Colombia.

Hypokalemic periodic paralysis

Hypokalemic periodic paralysis (hypoKPP) is a rare, autosomal dominant channelopathy characterized by muscle weakness or paralysis when there is a fall in potassium levels in the blood.

Latrotoxin

A latrotoxin is a high-molecular mass neurotoxin found in the venom of spiders of the genus Latrodectus (widow spiders).

LY294002

LY294002 is a morpholine-containing chemical compound that is a potent inhibitor of numerous proteins, and a strong inhibitor of phosphoinositide 3-kinases (PI3Ks).

Methyllycaconitine

Methyllycaconitine (MLA) is a diterpenoid alkaloid found in many species of Delphinium (larkspurs).

Motor nerve

A motor nerve is a nerve located in the central nervous system (CNS), usually the spinal cord, that sends motor signals from the CNS to the muscles of the body.This is different from the motor neuron, which includes a cell body and branching of dendrites, while the nerve is made up of a bundle of axons.

Neural facilitation

Neural facilitation, also known as paired pulse facilitation (PPF), is a phenomenon in neuroscience in which postsynaptic potentials (PSPs) (EPPs, EPSPs or IPSPs) evoked by an impulse are increased when that impulse closely follows a prior impulse.

Neuromuscular-blocking drug

Neuromuscular-blocking drugs block neuromuscular transmission at the neuromuscular junction, causing paralysis of the affected skeletal muscles.

Pinnatoxin

Pinnatoxins are neurotoxic chemical compounds that inhibit neuronal and muscle-type nicotine acetylcholine receptors.

Postsynaptic potential

Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse.

Quantal neurotransmitter release

Neurotransmitters are released into a synapse in packaged vesicles called quanta.

Repetitive nerve stimulation

Repetitive nerve stimulation is a variant of the nerve conduction study where electrical stimulation is delivered to a motor nerve repeatedly several times per second.

Summation (neurophysiology)

Summation, which includes both spatial and temporal summation, is the process that determines whether or not an action potential will be triggered by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).

Synaptic vesicle

In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse.

Synaptogenesis

Synaptogenesis is the formation of synapses between neurons in the nervous system.
