Several copies were purchased here at Duke University for evaluation. MacBrain had a reasonable mouse interface for placing neurons and for linking neurons, and had built-in rules for learning such as the delta-rule, back-propagation, and the Boltzmann machine. There was no language that allowed complicated networks to be set up, so drawing and linking more than about ten neurons was tedious and impractical. The program is slow, making scaling studies also impractical. The worst part of the product was that it was extremely buggy and many advertised features had not been implemented. Repeated calls to the makers of MacBrain at Neuronics led to promises that bug-free versions would be available any day now, but they never arrived. Neuronics also refused to refund our money. Try another product from more trustworthy company. Henry Greenside
