HUMAN BRAIN THE BUSY WORKER.....




 HUMAN BRAIN THE BUSY WORKER.....


The human brain contains 1011 neurons, which are thought to be its computational units. These cells are densely connected within the brain, with the average neuron making approximately 104 direct connections, or synapses, to other neurons. Surprisingly, these connections can fail to propagate up to 95% of neuronal signals during steady activity.
How do thought, perception, and creativity emerge fr...om the collective activity of the astronomical number of unreliable neurons that make up the human brain? Did these neurons evolve to become noisy, and why are noisy neuronal networks advantageous? What role does this noise and collective neuronal activity play in neurological diseases?
The Initiative for Collective Neuronal Dynamics and Epilepsy (ICNDE) is a scientific research organization founded to answer these fundamental questions and explore the nature of spatiotemporal patterns of neuronal activity in the brain. These patterns or collective excitations are ubiquitous in nature, occurring in noisy systems from semiconductors to ant colonies. In the brain, this coherent activity not only likely underlies cognitive processesand consciousness, but also is essential to our understanding of diseases of cognition and epilepsy. By engaging in this research, ICNDE hopes to make a significant impact in our understanding of the brain.,,,:))
