0.0 : Overall Perspective of Neural Science
What problems of Neural Science will be solved here
From 1950s to 2000s, the central focus of biology was on the gene, but now it has shifted to the neural science and specifically to the biology of mind.
We need to study the process which we perceive, act, learn, and remember:
- How does the brain conceive of the infinite, research new things, and how does it can produce the unbelievable individuality of human thoughts, feelings, and actions
- How are the mental capabilities distribute with in the organ
- How are different mental processes localized to specific combinations of regions in the brain
- What rules relate the anatomical organization and the cellular physiology of a region to its specific role in the neural architecture of the brain
- To what extent are mental processes hardwired into neural architecture of the brain
- What do genes contribute to behavior, and how is gene expression
- How does the experience alter the way the brain processes subsequent events, and to what degree is that processing unconscious
- What is the neural basis underlying neurological and psychiatric disease
These posts – about Principles of Neural Science – will attempt to address these questions, we will find how neural science is attempting to link logic of neural circuitry to the mind – how the activities of nerve cells within defined, neural circuits are related to the complexity of mental processes.
New Techniques Help Us See Brain
In the last several decades, many new techniques have been used to study brain. Now, molecular dynamics of interconnected circuits of cells has been link to the internal representations of perceptual and motor acts in the brain, and these internal mechanisms has been relate to observable behavior. New imaging techniques permit us to visualize the human brain in action – to identify specific regions of the brain associated with particular modes of thinking and feeling and their patterns of interconnections.
Two Parts of these Posts
In the first part of these posts, we consider how mental functions can be located in specific regions of the brain. In the later part we examine in detail: perception, action, motivation, emotion, development, learning ,and memory.
There are two chief ideas in my posts:
1. The specificity of the synaptic connections established during development underlie perception, action, emotion, and learning.
2. Innate(genetic) and environmental determinants of behavior
About the 2nd ideas, We specifically want to know how gene contribute to behavior. Behavior itself, of course, is not inherited. The DNA is inherited. Genes encode proteins, and the proteins are important for the development and regulation of the neural circuits that underlie behavior.
Environment influence begins in utero, and then become the prime importance after birth. And after that environment contingencies can in turn influence behavior by altering gene expression.
Modern Neural Science
Modern Neural Science has merged with molecular biology, neurophysiology, anatomy, developmental biology, and cell biology, and become a new science of mind.
Experimental cognitive psychology and clinical psychotherapy can now be strengthened by insights into the neural science of behavior and by imaging mental processes in action in real time.
This post is my first post about Neural Science, then we are going to details about the problems we present above. Good luck
