Similarly, Olshausen shows that if neural responses to natural movies are forced to be sparse and independent, the receptive fields that result resemble those found physiologically in V1. These two lines of research provide paradigmatic ex ...

Neural Oscillators on the Edge: Harnessing Noise to Promote Stability
... Abnormal neural oscillations are implicated in certain disease states, for example repetitive firing of injured axons evoking painful paresthesia, and rhythmic discharges of cortical neurons in patients with epilepsy. In other clinical conditions, the pathological state manifests as a vulnerability ...

How Does the Brain Work?
... Throughout the brain, neurons communicate with one another through interlocking circuits. When a neuron is stimulated, it generates a tiny electrical current, which passes down a fiber, or axon. The end of the axon releases neurotransmitters —chemicals that cross a microscopic gap, or synapse — to s ...
