24 Aug Coordinating Neural Pathways

Visual Association Pathways in the Brain

Specialization & Cross-Over A great deal of functional specialization and cross-over is evidenced in the brief summary in the table on functional morphology and descriptions of the areas of the brain covered in my last post. In fact, the extent to which many areas specialize is understood in minute detail, even to the functional segregation […]

23 Aug Specialized Instruments – Brain Areas

Brodmann map

Finding Functions on a Map Much of what we know about the functions of areas of the brain was discovered by Korbinian Brodmann in the early 1900s. He mapped the brain by sticking in many electrodes, eliciting cognitive responses such as making a sound or showing an image to trigger perception, and monitoring electrical activity. Now, […]

21 Aug How Do You Think?

Activated Network

Weighing the Options As part of my quest for the truly intelligent system, I have invested much in investigating and attempting to describe how people think. I am particularly concerned with how people integrate multiple ideas or constraints into their thinking and decision-making processes. More ideas help make better decisions: consider my posts on exformation and […]

18 Aug Neuromorphic Computing

Inside a Neuron

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 […]

17 Aug Stimuli

Cybernetic Eye

Responses to Stimuli When we speak of computational systems, we use words like “input” and “output” and “program“. When computers become able to communicate, understand and process knowledge in context, will we use different words: words that are more anthropomorphic? I’ve been playing with anthropomorphic concepts with MIPUS. In today’s post I will draw us […]

15 Aug MIPUS and Association Neurons

Coordinating Areas in the Cerebrum

Association Neurons ==> Coordination Association Neurons are tied to motor neurons, though they are much more numerous (30 to 1 ratio). They have multiple roles depending on where in the nervous system they are found. Innovateus has a convenient primer on this category of nerve cell. To understand the importance of association neurons, consider the plight […]

13 Aug MIPUS the Robot Assistant

MIPUS Graphical Study Aid I’d like to introduce you to a friend of mine: His name is MIPUS. The main intent of the Understanding Context blog is to investigate mechanical models of cognition. What do robots have to do with language understanding (my main focus), you may ask. As you can see in the illustration, […]

11 Aug Emotion – The Perturbable Mr. Amygdala

Amygdala in Man

Fear and the Amygdala Have you ever been asked not to be so emotional, or on the contrary, to show more emotion? Or have you been asked to suppress a specific emotion, such as fear? I recall a scene from an Indiana Jones movie in which, after a scene of amazing heroics, a pilot tells […]

09 Aug Emotional Intelligence

Emotions

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

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 […]
