All-or-None Subprocesses in the Learning of Complex Sequence+
This paper reports a study designed to investigate whether the all-or-none conception of the learning process can be extended to a learning task more complex than conditioning or simple verbal association. The experimental task is to learn numerical sequences by anticipating each new member of the sequences. Although the obtained sequence learning appears very complex, it proves to be analyzabl...
متن کاملGraded and All-or-None Electrogenesis in Arthropod Muscle
Graded electrically excited responsiveness of Romalea muscle fibers is converted to all-or-none activity by Ba(++), Sr(++), or Ca(++), the two former being much the more effective in this action. The change occurs with as little as 7 to 10 per cent of Na(+) substituted by Ba(++). The spikes now produced have overshoots and may be extremely prolonged, lasting many seconds. During the spike the m...
متن کاملAll-or-none craniorachischisis in Loop-tail mutant mouse chimeras.
Mouse embryos homozygous for the mutant gene Loop-tail (Lp) are characterized by craniorachischisis, an open neural tube extending from the midbrain to the tail. In the present study, experimental chimeric mice containing mixtures of genetically mutant (from Lp/+ x Lp/+ matings) and genetically normal cells were produced. Our aim was to determine whether a 'rescue,' phenotypic gradient, or inte...
متن کاملOn the all-or-none rule of conscious perception
What are the true functional underpinnings of perception, emotion, consciousness, and subconscious processes remains an unsolved question (Alivisatos et al., 2012). For example, it seems somewhat mysterious how one and the same structure of neural circuits—the human brain—sometimes allows conscious experience and sometimes does not allow it. We even do not know whether this owes to the alternat...
متن کاملGPRC6A: Jack of all metabolism (or master of none)
BACKGROUND GPRC6A, a widely expressed G-protein coupled receptor, is proposed to be a master regulator of complex endocrine networks and metabolic processes. GPRC6A is activated by multiple ligands, including osteocalcin (Ocn), testosterone (T), basic amino acids, and various cations. SCOPE OF REVIEW We review the controversy surrounding GPRC6A functions. In mice, GPRC6A is proposed to integr...
