Histo-Psychology Edit

Histo-Psychology is the study of Tissues and how they impact on Psychology


There are over 1000 tissues in the brain. Some impact on psychology and some don't. Graeme E. Smith, noted that while we often talk about Neuro-psychology, and Psychology tends to talk a lot about the arrangement of the brain at the Organ level, There is very little available on the Architecture of the Tissues that make up the brain, and how those affect the processing and ultimately the psychology of the brain.


Although we know that there are 120 different types of neurons in the Cerebral Cortex, and about 150 different types in the brain itself, The classification of these neurons depends very heavily on their physical structure. The output characteristics of any particular neuron seems however to depend more on the selection from some 200 ion channels, that it implements, than its shape.


It took scientists a long time to realize that individual neurons were not significant, that it was circuits of multiple neurons that were significant, and they still haven't managed to characterize many of the circuits of the brain. Simulations of neural networks have often been limited to homogeneous networks. To truly understand the brain at the histological level, we need to be able to simulate heterogeneous networks of neurons.


A basic model of Neural Function Edit

Although other disciplines have other models of neurons, Graeme E. Smith has suggested a three role model, in which a neuron is classified as being optimized for one of three different roles, Transport, Memory, or Processing. This does not meant that there aren't cells that are optimized for more than one role, but that one role usually dominates the cell and the other roles that the cell exibits support that main dominant role.


It should be noticed that Transport neurons are long and thin and tend to gather together into larger nerve clusters.

Memory Cells tend to want to interconnect with other surrounding neurons in laminae or layers of similar neurons forming relatively flat tissues, that might be crumpled in appearance without losing their identity as flat tissues.

Processing Cells, tend to want to have complex dendritic structures with many forks, and branches.


This can then be projected onto the tissues, in that transport tissues tend to be long and thin

Memory Tissues tend to be flat, and broad

Processing tissues tend to be globular and round.
