Russian physiologists

These plant species (not Pollen), according to the Russian physiologist and pharmacologist Prof. I.I.Brehkman, belong to the group that are called adapto ens, i.e. drugs. [Pg.112]

Russian physiologist Ivan Mikhaylovich Sechenov (1829-1905), who was first to propose it in 1873-1892. The value of this coefficient depends on water salinity and salt composition. However, for major salts of the solution (NaCl, CaCy these coefficients are approximately equal if their concentrations are expressed in gram-equivalents. That is why for accoxmting for the effect of dissolved salts is advisable to apply salinity expressed in gram-equivalents of NaCl. Equation (2.290) covers mostly nonpolar organic compounds. Activities coefficients of mineral nonpolar components hke HjS, COj, H SiO, H3BO3 etc., usually correlate in more complex way with water composition. [Pg.311]

Lorenz (1981) recognized that some appetitive behaviors are FAPs, endogenously released and terminated upon detection of the key stimulus for the consummatory act that is the objective of the search. But, he did not develop the theoretical implications of this idea. Instead we must turn to the Russian physiologists who have spent 50 years studying orienting reflexes (Sokolov, 1963 Voronin et al., 1965, see also Berlyne, 1960). [Pg.40]

Pavlov, Ivan (1849-1936) A Russian physiologist and psychologist, Pavlov began investigating the digestive system, which led to experiments with the effects of behavior on the nervous system and the body s automatic functions. He used animals in researching conditioned reflex actions to a variety... [Pg.2013]

Russian physiologists well into the 1950s accepted the reality of the hormones secretin and gastrin, but in their emphasis on the primacy of neural control of gastrointestinal function they relegated the hormones to the role of chemical transmitters of nerve impulses. ... [Pg.209]

This is an experimental, surgical technique introduced by the famous Russian physiologist-psychologist, Ivan Petrovich Pavlov. A portion of the stomach is brought to the body wall and formed into a pouch from which samples may be taken. Secretions in the pouch are the same as those in the stomach. [Pg.833]

Classical conditioning was discovered by Russian physiologist Ivan Pavlov, who found that dogs could be trained to salivate at the sound of a bell rung a few seconds before the dogs were fed. The reaction (salivation), he found, could be transferred to another stimulus (the sound of the bell) that would not normally produce this reaction. [Pg.95]

Prepare a report on the research performed by Russian physiologist Ivan Pavlov on classical conditioning. Refer to Reference 1 or some other introductory textbook in psychology. [Pg.108]

The next layer in material selection based on feel involves the concept of response. Like all animals, humans respond to sensory input. The response may be an involuntary action (like your knee kicking out), a body sensation (feeling dizzy), a physical action (salivating when you smell food), an emotional response (feeling happy when you hug your child), or a combination of these items. It may also involve an intellectual assessment, where one evaluates the sensory input and makes a conscious decision on what actions to take next (such as whether or not they should yell Turn that music down ). These responses may also be affected by conditioning (either intentional or unintentional). The Russian physiologist Ivan Pavlov... [Pg.259]
