Acetylcholine

Acetylcholine (ACh) is an organic compound that functions in the brain and body of many types of animals (including humans) as a neurotransmitter.

See Orexin-A and Acetylcholine

Cysteine

Cysteine (symbol Cys or C) is a semiessential proteinogenic amino acid with the formula.

See Orexin-A and Cysteine

Disulfide

In chemistry, a disulfide (or disulphide in British English) is a compound containing a functional group or the anion.

See Orexin-A and Disulfide

Dopamine

Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells.

See Orexin-A and Dopamine

G protein-coupled receptor

G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular responses.

See Orexin-A and G protein-coupled receptor

Glucose

Glucose is a sugar with the molecular formula.

See Orexin-A and Glucose

Histamine

Histamine is an organic nitrogenous compound involved in local immune responses communication, as well as regulating physiological functions in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus.

See Orexin-A and Histamine

Lateral hypothalamus

The lateral hypothalamus (LH), also called the lateral hypothalamic area (LHA), contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature, digestive functions, and blood pressure, among many others.

See Orexin-A and Lateral hypothalamus

Memory

Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed.

See Orexin-A and Memory

N-terminus

The N-terminus (also known as the amino-terminus, NH2-terminus, N-terminal end or amine-terminus) is the start of a protein or polypeptide, referring to the free amine group (-NH2) located at the end of a polypeptide.

See Orexin-A and N-terminus

Narcolepsy

Narcolepsy is a chronic neurological disorder that impairs the ability to regulate sleep–wake cycles, and specifically impacts REM (rapid eye movement) sleep.

See Orexin-A and Narcolepsy

Neuron

A neuron, neurone, or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.

See Orexin-A and Neuron

Neuropeptide

Neuropeptides are chemical messengers made up of small chains of amino acids that are synthesized and released by neurons. Orexin-A and Neuropeptide are neuropeptides.

See Orexin-A and Neuropeptide

Norepinephrine

Norepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as a hormone, neurotransmitter and neuromodulator.

See Orexin-A and Norepinephrine

Orexin

Orexin, also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. Orexin-A and Orexin are molecular neuroscience, neuropeptides and orexin receptor agonists.

See Orexin-A and Orexin

Orexin receptor

The orexin receptor (also referred to as the hypocretin receptor) is a G-protein-coupled receptor that binds the neuropeptide orexin.

See Orexin-A and Orexin receptor

Peptide

Peptides are short chains of amino acids linked by peptide bonds.

See Orexin-A and Peptide

Placebo

A placebo is a substance or treatment which is designed to have no therapeutic value.

See Orexin-A and Placebo

Positron emission tomography

Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.

See Orexin-A and Positron emission tomography

Protein isoform

A protein isoform, or "protein variant", is a member of a set of highly similar proteins that originate from a single gene or gene family and are the result of genetic differences.

See Orexin-A and Protein isoform

Pyroglutamic acid

Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid) is a ubiquitous but understudied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.

See Orexin-A and Pyroglutamic acid

Rhesus macaque

The rhesus macaque (Macaca mulatta), colloquially rhesus monkey, is a species of Old World monkey.

See Orexin-A and Rhesus macaque

Treatment and control groups

In the design of experiments, hypotheses are applied to experimental units in a treatment group.
