Semiotics (/ ˌ s ɛ m i ˈ ɒ t ɪ k s / SEM-ee-OT-iks) is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter. Semiosis is any activity, conduct, or process that involves signs.
The term was introduced by Charles Sanders Peirce (1839–1914) to describe a process that interprets signs as referring to their objects, as described in his theory of sign relations, or semiotics. Other theories of sign processes are sometimes carried out under the heading of semiology , following on the work of Ferdinand de Saussure (1857 ...
DOI is a serotonin 5-HT 2A, 5-HT 2B and 5-HT 2C receptor agonist. [4] It is said to be approximately 5- to 12-fold selective for the serotonin 5-HT 2A receptor over the serotonin 5-HT 2C receptor. [7] The drug is not a monoamine releasing agent of serotonin or dopamine. [8] DOI is an agonist of the rat trace amine-associated receptor 1 (TAAR1). [9]
Biosemiotics (from the Greek βίος bios, "life" and σημειωτικός sēmeiōtikos, "observant of signs") is a field of semiotics and biology that studies the prelinguistic meaning-making, biological interpretation processes, production of signs and codes and communication processes in the biological realm.
An agonist is a chemical that activates a receptor to produce a biological response. Receptors are cellular proteins whose activation causes the cell to modify what ...
A receptor modulator, or receptor ligand, is a general term for a substance, endogenous or exogenous, that binds to and regulates the activity of chemical receptors.They are ligands that can act on different parts of receptors and regulate activity in a positive, negative, or neutral direction with varying degrees of efficacy.
Semiotics can be described as all of the following: Academic discipline – branch of knowledge that is taught and researched at the college or university level. . Disciplines are defined (in part), and recognized by the academic journals in which research is published, and the learned societies and academic departments or faculties to which their practitio
Functional selectivity has been proposed to broaden conventional definitions of pharmacology.. Traditional pharmacology posits that a ligand can be either classified as an agonist (full or partial), antagonist or more recently an inverse agonist through a specific receptor subtype, and that this characteristic will be consistent with all effector (second messenger) systems coupled to that ...
