  2. A Logical Calculus of the Ideas Immanent in Nervous Activity

    en.wikipedia.org/wiki/A_logical_calculus_of_the...

    Theorem 4 and 5 state that these are equivalent. They considered three forms of excitation: spatial summation, temporal summation, and facilitation. The definition above is spatial summation (which they pictured as having multiple synapses placed close together, so that the effect of their firing sums up).

  3. Summation (neurophysiology) - Wikipedia

    en.wikipedia.org/wiki/Summation_(neurophysiology)

    Basic ways that neurons can interact with each other when converting input to output. Summation, which includes both spatial summation and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs ...

  4. Synaptic potential - Wikipedia

    en.wikipedia.org/wiki/Synaptic_potential

    Temporal summation refers to successive excitatory stimuli on the same location of the postsynaptic neuron. Both types of summation are the result of adding together many excitatory potentials; the difference being whether the multiple stimuli are coming from different locations at the same time (spatial) or at different times from the same ...

  5. Excitatory synapse - Wikipedia

    en.wikipedia.org/wiki/Excitatory_synapse

    Temporal summation occurs when a particular synapse is stimulated at a high frequency, which causes the postsynaptic neuron to sum the incoming EPSPs and thus increases the chance of the neuron firing an action potential.

  6. Neurotransmission - Wikipedia

    en.wikipedia.org/wiki/Neurotransmission

    Neurotransmission (Latin: transmissio "passage, crossing" from transmittere "send, let through") is the process by which signaling molecules called neurotransmitters are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and react with the receptors on the dendrites of another neuron (the postsynaptic neuron) a ...

  7. Coincidence detection in neurobiology - Wikipedia

    en.wikipedia.org/wiki/Coincidence_detection_in...

    Coincidence detection is a neuronal process in which a neural circuit encodes information by detecting the occurrence of temporally close but spatially distributed input signals. Coincidence detectors influence neuronal information processing by reducing temporal jitter and spontaneous activity, allowing the creation of variable associations ...

  8. Threshold potential - Wikipedia

    en.wikipedia.org/wiki/Threshold_potential

    A. A schematic view of an idealized action potential illustrates its various phases as the action potential passes a point on a cell membrane. B. Actual recordings of action potentials are often distorted compared to the schematic view because of variations in electrophysiological techniques used to make the recording.

  9. Semantic processing - Wikipedia

    en.wikipedia.org/wiki/Semantic_Processing

    It is believed that the left hemisphere of the brain dominates convergent semantic processing due to the fine grained, small window of temporal integration. [ 1 ] [ 2 ] Spatially, neurons in the left hemispheres occupy mutually exclusive regions, allowing for the more fine-tuned response seen in convergent semantic processing.
