Nod (gesture)

A nod of the head is a gesture in which the head is tilted in alternating up and down arcs along the sagittal plane. In many cultures, it is most commonly, but not universally, used to indicate agreement, acceptance, or acknowledgment.

Nodding to indicate acceptance

Different cultures assign different meanings to the gesture. Nodding to indicate "yes" is widespread, and appears in a large number of diverse cultural and linguistic groups. Areas in which nodding generally takes this meaning include the Indian subcontinent (note that the head bobble also shows agreement there), Iran, Southeast Asia, most of Europe (see below), Latin America and North America. Nodding may also be used as a sign of recognition in some areas. Nodding is also used to show respect. Insult can be inferred if it is not returned in kind.

Origin

There are varying theories as to why nodding is so frequently used to mean "yes". One simple theory is that it is a form of bowing, indicating that one is prepared to accept what another person is saying or requesting. It has also been stated that babies, when hungry, search for milk by moving their heads vertically, but decline milk by turning their head from side to side.

NOD, Nod, or nod may refer to:

NOD2

Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) also known as caspase recruitment domain-containing protein 15 (CARD15) or inflammatory bowel disease protein 1 (IBD1) is a protein that in humans is encoded by the NOD2 gene located on chromosome 16. NOD2 plays an important role in the immune system. It recognizes bacterial molecules (peptidoglycans) and stimulates an immune reaction.

NOD2 is an intracellular pattern recognition receptor, which is similar in structure to resistant proteins of plants and recognizes molecules containing the specific structure called muramyl dipeptide (MDP) that is found in certain bacteria.

Structure

The C-terminal portion of the protein contains a leucine-rich repeat domain that is known to play a role in protein–protein interactions. The middle part of the protein is characterized by a NOD domain involved in protein self-oligomerization. The N-terminal portion contains two CARD domains known to play a role in apoptosis and NF-κB activation pathways.

Gesture

A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak.

Gesture processing takes place in areas of the brain such as Broca's and Wernicke's areas, which are used by speech and sign language. In fact, language is thought by some scholars to have evolved in Homo sapiens from an earlier system consisting of manual gestures. The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language.

Musical gesture

In music, gesture is any movement, either physical (bodily) or mental (imaginary). As such "gesture" includes both categories of movements required to produce sound and categories of perceptual moves associated with those gestures. The concept of musical gestures has received much attention in various musicological disciplines (e.g. music analysis, music therapy, music psychology, NIME) in recent years.

For example, the "musical" movement from a close-position tonic C major chord to a close-position dominant G major chord requires on the piano the physical movement from each white key of the first chord to the right (in space, upwards in pitch) four white keys or steps. Thus gesture includes both characteristic physical movements by performers and characteristic melodies, phrases, chord progressions, and arpeggiations produced by (or producing) those movements.

Introduction

The concept of musical gestures encompasses a large territory stretching from details of sound-production to more global emotive and aesthetic images of music, and also include considerations of cultural-stylistic vs. more universal modes of expression. In all cases, it is believed that musical gestures manifest the primordial role of human movement in music. For this reason, scholars speak of embodied music cognition in the sense that listeners relate musical sound to mental images of gestures, i.e. that listening (or even merely imagining music) also is a process of incessant mental re-enactment of musical gestures.
