Early brain wiring: activity-dependent processes.
One of the leading theories of the neuropathology of schizophrenia is that it is a developmental disorder of "neural connectivity." To assess this theory, it is first necessary to understand how precise neural connections normally are established. Sensory-driven neural activity has been widely recognized as crucial for this process. Recent studies have revealed a similar requirement for endogen...
متن کاملWiring Optimization in the Brain
La Jolla, CA 92037 [email protected] The complexity of cortical circuits may be characterized by the number of synapses per neuron. We study the dependence of complexity on the fraction of the cortical volume that is made up of "wire" (that is, ofaxons and dendrites), and find that complexity is maximized when wire takes up about 60% of the cortical volume. This prediction is in good agreement w...
متن کاملDiscovering the wiring diagram of the brain
he brain, the seat of our cognitive abilities, is perhaps the most complex puzzle in all of biology. Every second in the human brain, billions of cortical nerve cells transmit billions of messages and perform extraordinarily complex computations. How the brain works—how its function follows from its structure—remains a mystery. The brain's vast numbers of nerve cells are interconnected at synap...
متن کاملNeuronal processes underlying rhythmic brain activity.
The neuroelectric activity of the brain provides a variety of instances of rhythmic events. The periodicity of such events ranges from milliseconds in the case of the firing of individual neurons t o circadian in the case of certain aspects of the "sleep" EEG. This paper will (be devoted t o a discussion of (i) methodological approaches to the detection and description of s6me of the shorter pe...
متن کاملElectrical Wiring of the Oscillating Brain
In this issue of Neuron, two laboratories (Deans et al. and Hormuzdi et al.) find that cortical gamma oscillation in vitro is impaired in the Cx36 knockout mouse. What are the implications?
