We provide an overview and comparison of several recent large-scale brain models. In addition to discussing challenges involved with building large neural models, we identify several expected benefits of pursuing such a research program. We argue that these benefits are only likely to be realized if two basic guidelines are made central to the pursuit. The(More)
Hippocampal cells replay sequences of neural activity that have been experienced in the past, implicating the hippocampus in episodic memory. We present a spik-ing-neuron attractor network model that can encode arbitrary experiences in a combination of learned connection weights and neural activity. The model can then recall part or all of the encoded(More)
I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract As we experience life, we are constantly creating new memories, and the hippocampus plays an important(More)
work model of visual motion processing and perceptual decision making, independent of the number of choice alternatives. As an application we simulate the two-alternative forced choice (2AFC) task. The integration of local dot velocities over time produces a decision vector that depends on the nature of the sensory input, processing and integration(More)
