Sample text

The preparation is used for intracellular recording from central neurons (with the central nervous system intact and connected to the periphery). The mollusk receives whole-body tactile stimuli, CS+ and CS− , from an electrical stimulator ES1 and ES3 by means of inductance and whole-body painful US from an electrical stimulator ES2 . During operant conditioning the mollusk receives an US in those cases in which beforehand chosen trained neuron does not generate an instrumental action potential.

It has become apparent that no single memory center exists, and many parts of the nervous system participate in the representation of any single event. Extirpations of brain tissue or other influences to neural centers have not revealed the center of memory and give rise to the hypothesis that the ability to memorize is an inalienable property of any neuron. K. Lashley formulated the law of mass action, according to which the extent of a memory defect in rats may be correlated with the size of the cortical area removed, but not with its specific location [705].

In the complex (although discrete) environment an animal tries to accomplish some simple variants of complex chains of reflexes, in order to reach the reinforcement. Such erroneous movements can more exactly be considered as ”probing” movements of accidental choice from a set of preferable actions [1251]. Sometimes, mistakes during trial-and-error behavior happen because of a shortage of reliable information from the environment or due to failures in memory for information necessary to perform the task successfully.
