01 Dec Robot Neurons: Analog versus Digital
Digital is basically black and white: 1 is yes and 0 is no or vice-versa. Yet our world is full of other colors. We can efficiently use digital devices to stretch arbitrary numbers of 1’s and 0’s together to represent a virtually infinite degree of possible values. Yet there are places where exactly two values may […]
06 Sep Varieties of Neural Circuits in the Cerebellum
The Cerebellum In this post we explore the roles and varieties of neural circuits of the cerebellum in motor control and the maintenance of life-support systems. The layers of the cerebellum have different cell populations, and the types of cells have radically different forms. Three main points will be made today: the morphology of cells and layers […]
05 Sep Brain Form and Function
Functional Morphology I’ve addressed questions related to modeling form, function and process in an earlier post. Today’s post drills down in some specific areas to point out some important connections between form and function that could contribute to engineering systems that more accurately model the human brain. Paul Churchland suggests that many AI initiatives have […]
29 Aug Black Boxes: Specialized Areas of the Brain
The Black Box Black Box is a term used to describe a mechanical device that does something inside, but whose functions are not visible from the outside. Specialized areas of the brain may operate as black boxes. Activation flows in and activation flows out, and what happens inside may have no direct affect on other […]
28 Aug Sensory Input to the Brain
Part of the definition of any computer program is defining the inputs and outputs, where they come from, what they are and where they get processed. Fortunately, we know enough about the brain to answer many of these questions, thus we have a basis for defining artificial models that, in some way, mimic these elements of […]
27 Aug Brain Correlation Processes
Many computer systems focus on a single capability, one task or just one dimension of a complex process. Sentient brain activity is an example of a complex process with many dimensions. Optical character recognition, such as identifying a capital “Q” on a piece of paper, is an example of a problem with three dimensions: Length, […]
18 Aug Neuromorphic Computing
To Mimic is Human When is imitation not flattering or sincere? I try to be sincere in my blogging, and I have tried not to unnecessarily emphasize the computing ability of the human brain, but the whole point of this blog is to imitate it using computers. A neuromorphic (resembling the brain and/or neurons) computing model […]
09 Aug Emotional Intelligence
What Does it Take to Think In describing the role of the hippocampus, we discussed the correlation of various sensory inputs to form a cohesive picture of our physical surroundings. The direct links between the amygdala and the central gray matter demonstrate the importance of emotional feedback or emotional intelligence in cognitive processes. Dr. Travis […]
06 Aug Finding yourself in the Hippocampus
On October 6, 2014, the Nobel Assembly at Karolinska Institutet awarded The 2014 Nobel Prize in Physiology or medicine to John O´Keefe and to May‐Britt Moser and Edvard I. Moser for their discoveries of cells that constitute a positioning system in the brain. John O´Keefe is Director of the Sainsbury Wellcome Centre in Neural Circuits […]
