(From BU Today) “That is a ball.” “I do believe that is a cone.” “Seems like a wonderful book.” The voice is mechanical and flat, and anyone offering such banal commentary and sounding so bored would surely bomb in a job interview. But in this case, the observations are impressive. They’re made by what looks like a two-foot-tall stack of hors d’oeuvre trays on wheels, careening around the floor and proclaiming its discoveries as its “eye,” an attached camera, falls on them.

A slightly different post ..... away from robot and GPU! Today, I want to point to a new article titled Resonant Cholinergic Dynamics in Cognitive and Motor Decision-Making: Attention, Category Learning, and Choice in Neocortex, Superior Colliculus, and Optic Tectum was published on Frontiers in Neuroscience (20 January 2016 | http://dx.doi.org/10.3389/fnins.2015.00501). The article, directly derived from my PhD research on laminar mechanisms of memory and perception in the cerebral cortex, was written in collaboration with Jesse Palma. This article, freely available online, elaborates on links between ... a cup of coffee (cholinergic modulation!!!!), attention, learning, and decision making within several brain systems, both cognitive and motor.
Selecting relevant sensory information while interacting with a changing environment is a key feature not only in robotsof animal intelligence. This selection is necessary to direct limited sensory, cognitive, and motor resources toward the important stimuli in the environment, and to choose a set of motor commands that correspond to behavioral goals. The present article proposes how cholinergic modulation of cognitive and sensory-motor circuits may realize such selectivity in a task-sensitive way. Understanding how animals can solve this, can help build more intelligent machines.

What will it take to get robots out of YouTube and into our day to day lives? Max Versace, Director of the Boston University Neuromorphics Lab, talks about the state of the art in robotic bodies, brains and minds. He says that in just a few years, it will be robotic intelligence that will make the next leap forward.
In just a little more than 10 minutes, Dr. Versace presented the trends in a compelling presentation at the MassTLC Future of Robotics Summit on December 13, 2013. Watch the video and go on a journey to Mars and the brain of a mouse.

I was recently interviewed by Scope, a publication established in 2005 to showcase the work undertaken by the students in the MIT Graduate Program in Science Writing. The interview was about a research project led by Chi-Sang Poon, whose MIT group has designed a chip emulating in detail the dynamics of brain synapses, the junctions between neurons.

On Friday, September 16, 2011 Boston University chartered a vibrant new center to house research in Computational Neuroscience and Neural Technology (CompNet). In addition to some new areas of emphasis CompNet will support many aspects of the research mission of the former Department of Cognitive and Neural Systems (CNS). The closing of the CNS Department affords an opportunity to reflect on an epoch through the lens of the Outstein symbol that came to be its de facto logo. On the left, the Outstein logo.

The Computational Neuroscience PhD specialization of Boston University’s Graduate Program for Neuroscience provides students with a uniquely specialized curriculum that supplements core neuroscience coursework with advanced training in a wide array of computational methods for studying the nervous system and developing neuroscience-related technologies. Topics of study include: neural network modeling, neural dynamics, sensory, motor, and cognitive modeling, statistical modeling, sensory and motor prosthesis, brain-machine interfaces, neuroinformatics, neuromorphic engineering, and robotics. Coursework is chosen from the wide array of computational and neuroscience courses offered by the many departments and programs of the main Boston University campus and the BU School of Medicine. Students pursue their research interests in laboratories across the University and have the opportunity to combine hands on experimental research with highly sophisticated computational analysis.

More than anything, the neocortex makes us human, so it has been said. Humans are better than any other living things at reading blog posts, scheduling daily activities, and filling out tax forms, among other things mundane and not. Much progress has been made localizing certain functions to certain areas of the brain, in the neocortex in particular. Other questions remain unanswered. These include how function arises from form: how do the individual neurons cooperate together to process and combine information? What is the role of each of the six neocortical layers in information processing? What impact does network connectivity have on the shape of dynamics? How do neuronal oscillations and rhythms help process information? How are different aspects of cognition coordinated? These questions are often difficult or impossible to answer from in-vivo measurements, not only because it is currently impossible to measure the state of all neurons in the brain, but also because knowledge of the state of each neuron would create an insurmountably large dataset that would be difficult to interpret.

Numenta is a neuromorphic technology company, founded in 2005 by Dileep George (then a graduate student at Stanford), and Jeff Hawkins (founder of Palm Computing). Numenta’s Hierarchical Temporal Memory (HTM) is a hierarchical Bayesian model based on the theory of cortical function outlined in Hawkins's book, On Intelligence. It has been used in commercial applications such as a video monitoring application, and web analytics. This post introduces Neurdon readers to HTM. Read the rest of this entry »

Previously I demonstrated how to represent and simulate models of individual neurons using Python. In this next series of articles I'm going to show how Python can be used to simulate connected networks of spiking neurons. Modeling and evaluating these networks can give us an insight into how populations of neurons in the brain interact to give rise to various observed phenomena. Lateral and feedback recurrent networks are of particular interest for computational simulation as attempting to analytically describe these systems quickly becomes intractable. First I'm going to start off with some of the most basic recurrent networks. Read the rest of this entry »
