  2. Positive feedback - Wikipedia

    en.wikipedia.org/wiki/Positive_feedback

    Positive feedback is used in digital electronics to force voltages away from intermediate voltages into '0' and '1' states. On the other hand, thermal runaway is a type of positive feedback that can destroy semiconductor junctions. Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions.

  3. Feedback - Wikipedia

    en.wikipedia.org/wiki/Feedback

    Positive feedback occurs when the fed-back signal is in phase with the input signal. Under certain gain conditions, positive feedback reinforces the input signal to the point where the output of the device oscillates between its maximum and minimum possible states. Positive feedback may also introduce hysteresis into a circuit. This can cause ...

  4. Biological applications of bifurcation theory - Wikipedia

    en.wikipedia.org/wiki/Biological_applications_of...

    Biological applications of bifurcation theory provide a framework for understanding the behavior of biological networks modeled as dynamical systems.In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system.

  5. Positivity offset - Wikipedia

    en.wikipedia.org/wiki/Positivity_offset

    In psychology, the positivity offset is a phenomenon where people tend to interpret neutral situations as mildly positive, and rate their lives as good, most of the time. The positivity offset stands in notable asymmetry to the negativity bias .

  6. Behavioral neuroscience - Wikipedia

    en.wikipedia.org/wiki/Behavioral_neuroscience

    The term "psychobiology" has been used in a variety of contexts, emphasizing the importance of biology, which is the discipline that studies organic, neural and cellular modifications in behavior, plasticity in neuroscience, and biological diseases in all aspects, in addition, biology focuses and analyzes behavior and all the subjects it is ...

  7. Biochemical switches in the cell cycle - Wikipedia

    en.wikipedia.org/wiki/Biochemical_switches_in...

    Positive feedback loops play a role by switching cells from low to high Cdk-activity. The interaction between the two types of loops is evident in mitosis. While positive feedback initiates mitosis, a negative feedback loop promotes the inactivation of the cyclin-dependent kinases by the anaphase-promoting complex.

  8. Hodgkin cycle - Wikipedia

    en.wikipedia.org/wiki/Hodgkin_Cycle

    In membrane biology, the Hodgkin cycle is a key component of membrane physiology that describes bioelectrical impulses, especially prevalent in neural and muscle tissues. It was identified by British physiologist and biophysicist Sir Alan Lloyd Hodgkin.

  9. Physiological psychology - Wikipedia

    en.wikipedia.org/wiki/Physiological_psychology

    Various forms of psychology concentrations are included in the sectors of health psychology, forensic psychology, clinical psychology, industrial and organizational psychology, and school psychology. Health psychology is a discipline that understands the psychological, behavioral, and cultural aspects that affect the physical health and ...
