Usage examples of "activated".

The shape of the basilar membrane and its position in the ear are such that there is a direct correspondence between the frequency of each sine wave component of a sound and the positions of the hair cells activated by that component.

There is an intrinsic plausibility to this theory: if two neurons A and B have inputs to C, and if the activation of C is stronger when its inputs come in repeatedly at almost exactly the same time, then neuron C will be more strongly activated if its inputs A and B are synchronous.

Since C is active in the map, and D is not very active, the consonant relationship with C causes E to be activated in the map.

Finally G enters the map and becomes activated because it is harmonically related to both the notes already active.

The intensity of the response to a given beat reflects the current dominance of the beat period whose corresponding neurons are activated by that beat.

Neurons are activated by pitch, in inverse proportion to the speed at which the pitch in the melody is changing.

The competition for the two states is won by whichever chord has its neurons activated first, i.

Since, in practice, neurons that input into a neuron must have either inhibitory or excitatory connections, each musicality neuron must have a fixed division of its inputs into those expected to be active and those expected to be inactive, and the musicality neuron will only be activated when the actual activity of the neurons that it receives input from takes on this pattern.

For each cortical map, the number of ways the cortical map can be activated over a period of time is very large compared to the number of ways it can be activated that produce a constant activity pattern.

It is not the primary purpose of the bass accompaniment to activate those maps activated by other features of melody, or to activate those maps that respond to rhythmical features.

Portions of the brain can be artificially activated or deactivated by various means, and the effects of this observed.

Neurons in the network would become activated and reactivated by corresponding pitch values, and their activity would decay slowly.

Somewhere in between the point where the sensory cells in our eyes are activated, and the point where neurons in the speech areas of the brain select which words to say, there must have been a conversion from intensity-based encoding to position-based encoding.

The cortical map that responds to chords is one that is activated by pitch values that are consonantly related to pitch values already active in the map.

There is a cortical map that contains a map of neurons activated by the occurrence of regular beats of fixed tempos.
