Computational Model Linking Neural Activity to Behavior
A big question in neuroscience is how neural activity represents knowledge. We can use modelling to explore how different levels of neural activity- subthreshold currents, action potentials, local ...

Can processing effort for sub-tasks in neural networks be measured?
I often heard statements like:
80% of your brain processing is computing the effect of gravity
or, similarily:
You only use 20% of your brain power
My question isn't about the truth of ...

How can STDP fit with reciprocal connectivity?
I have rather technical question regarding STDP dynamics.
I am working on a neural network implementing an STDP learning algorithm, and have noticed that it is extremely anti-reciprocal. When two ...

What explains variability in the mean firing rate across biological neurons?
Biological neurons have a trade-off between high information transfer (high firing rate) and energy conservation (low firing rate). One would suspect that the maximization of this function has a ...

References for biologically plausible models of knowledge representation?
I'm looking for references that deal with the issue of how various kinds of semantic knowledge is (or might be) neurally represented. Most of the discussion of this topic seems skewed by social ...

Neural networks with biologically plausible accounts of neurogenesis
One of the reasons artificial neural net algorithms like cascade correlation (pdf) have been generating interest is because they start with a minimal topology (just input and output unit) and recruit ...
