  2. Addiction-related structural neuroplasticity - Wikipedia

    en.wikipedia.org/wiki/Addiction-related...

    These neurons project inhibitory connections to the VTA and receive excitatory input from various other structures in the limbic system. Changes in the excitatory synaptic inputs into these neurons have been shown to be important in mediating addiction-related behaviors. [43] It has been shown that LTP and LTD occurs at NAc excitatory synapses ...

  3. Mirror neuron - Wikipedia

    en.wikipedia.org/wiki/Mirror_neuron

    In these monkeys, mirror neurons are found in the inferior frontal gyrus (region F5) and the inferior parietal lobule. [1] Mirror neurons are believed to mediate the understanding of other animals' behaviour. For example, a mirror neuron which fires when the monkey rips a piece of paper would also fire when the monkey sees a person rip paper ...

  4. Hebbian theory - Wikipedia

    en.wikipedia.org/wiki/Hebbian_theory

    Hebbian learning and spike-timing-dependent plasticity have been used in an influential theory of how mirror neurons emerge. [14] [15] Mirror neurons are neurons that fire both when an individual performs an action and when the individual sees [16] or hears [17] another perform a similar action. The discovery of these neurons has been very ...

  5. Associative sequence learning - Wikipedia

    en.wikipedia.org/wiki/Associative_Sequence_Learning

    The fact that mirror system activation is sensitive to sensorimotor expertise, provides a strong indication that the properties of mirror neurons are acquired through learning. Heyes and colleagues have also shown that a number of imitative effects, thought to be mediated by the mirror system, may be reversed through periods of 'counter-mirror ...

  6. Christian Keysers - Wikipedia

    His team uncovered a mechanism responsible for emotional contagion by showing that rats have neurons in the cingulate cortex, a region involved in nociception, that respond both when a rat experiences pain and when it witnesses another animal experience pain, providing the first systematic evidence for the presence of emotional mirror neurons ...

  7. The Tell-Tale Brain - Wikipedia

    en.wikipedia.org/wiki/The_Tell-Tale_Brain

    Chapters four and five talk about mirror neurons, while chapter six discusses human language. Ramachandran proposes "nine laws of aesthetics ," which he discusses in chapters seven and eight. The final chapter, chapter nine, "The Ape With A Soul" concerns introspection and human self-awareness.

    The term Mirror cell may be used as: Colloquial term for Mirror neuron , a specialized brain neuron Mirror support cell which supports the primary mirror in a reflecting telescope

  9. Evolutionary models of human drug use - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_models_of...

    The hijack model of substance addiction suggests that Psychoactive drugs act on ancient and evolutionarily conserved neural mechanisms associated with positive emotions that evolved to mediate incentive behavior. [1] [2] They induce emotions that in human evolutionary history signaled a benefit for the group. Modern drugs tap into these ...
