We constantly change our behavior between things like driving a car to chopping an onion. How does the brain switch quickly between different sensory-motor pathways…

Finding an Alternative to Connectionism
Mainstream theory of brain function revolves around patterns of connectivity. Could the adaptations of neurons be an alternative anchor that provides greater insight? Today’s mainstream…
Predicting Human Behavior with Diffusion Models
Random walk or diffusion models have been successful at predicting human decision making and guiding experiments. Here’s why. In my last post I described two…
Two Successful Theories in Biology
The theory of evolution and the Hodgkin-Huxley model of the action potential are two successful theories in biology that are relevant to the brain. Why…
Constructing a Theory of the Brain
What are the necessary elements for a genuine theory of the brain and what will it take to construct one? In my previous posts I…
Engineering a Brain: Can This Work?
Many theoretical proposals in neuroscience are presented in the form of an engineering solution. But engineering a solution is a different process than creating a…
Building The Brain With Modules
Models in computational neuroscience that solve for one outcome cannot combine with one that solves for another. Can a modular approach solve this? The short…
The Crisis of Computational Neuroscience
Computational Models attempt to explain the behavior of the brain using neural network simulations, but assumptions that help simulate one phenomenon are destructive to the…
Finding your Grandmother Inside Your Head
How do you perceive your Grandmother? It is still not known how the activity of neurons represent complex perceptual objects with many features. The theories…
The Puzzle of Working Memory
Working memory, the capacity to keep things ‘in mind’ such as a phone number, is a phenomenon poorly understood in Neuroscience. What do we know…
