Learning about Learning - by Directly Driving Networks of Neurons
Learning about Learning - by Directly Driving Networks of Neurons

... New behaviors require new patterns of neural activity among the population of neurons that control behavior. How can the brain find a pattern of activity appropriate for the desired behavior? Why does that learning process take time? To tackle questions like these, we reverse the normal order of ope ...

... Networks of integrate-and-fire neurons with recurrent feedback can perform analog to digital conversion at a rate that is proportional to the size of the network (E.K.Ressler et al, 2004, Proc. SPIE Int. Soc. Opt. Eng. 5200, 91). The individual neurons are coordinated using feedback in a manner that ...

... Sensory neurons carry the impulses to the spinal cord by way of the dorsal root. An interneuron picks up the impulse from the sensory and transmits it to the motor neuron. At the same time the impulse is also transmitted to the brain. The motor neuron stimulates the specific effector organ to make t ...

Central pattern generator

Central pattern generators (CPGs) are biological neural networks that produce rhythmic patterned outputs without sensory feedback. CPGs have been shown to produce rhythmic outputs resembling normal ""rhythmic motor pattern production"" even in isolation from motor and sensory feedback from limbs and other muscle targets. To be classified as a rhythmic generator, a CPG requires:1. ""two or more processes that interact such that each process sequentially increases and decreases, and 2. that, as a result of this interaction, the system repeatedly returns to its starting condition.
