The individual personality consists of cognition, emotion, and behavior of himself or herself across the culture according to the philosophers in western and eastern countries.
There are approximately one hundred billion neurons (cells) in the human brain, composed of thousands of distinct types of cells versus a few distinct types of cells in the heart and liver. The primary elements of communication are not neurons but synapses, the specialized gaps across which neurons communicate with each other. Neurons in the brain generally form thousands of synapses with neighboring distant neurons. Overall, there are likely to be more than 100 trillion synapses in a single human brain.
In synapses, there are hundreds of neurotransmitters (neurochemistries) discovered so far that are actively working between the presynaptic receptor and postsynaptic receptor. The processing of sensory information and the production of motor or endocrine outputs is carried out in the brain by neurons arrayed in precise networks, which we call circuitry.
A synapsis can be excitatory (+1) or inhibitory (-1) and the strength of a synapsis can be any number between -1 and +1 and is referred to as the weight of the synapsis.
The major neurotransmitters are glutamate (excitatory) GABA (inhibitory), Dopamine, Norepinephrine, and Serotonin, and etc…The concept of neuromodulation and neuroplasticity based upon neurotransmitter interaction in the synapsis will be the highlight of cognitive neuroscience. The learning, memory and information as well as experience and the culture depend upon the weight of synapsis. The neuronetwork through synaptic transmission is more or less influenced by learning and education than genetically determined (approximately 8%).
When one receives sensory perception (input) from the environment or world, which the spinal cord first gets this perception (input) and passes through the brain stem and arrives to the amygadala (part of limbic system, emotional brain), where emotion arises and where emotional memory occurs. The behavior forms interaction between emotional brain and cerebral cortex with sensory motor functioning in the basal ganglia and cerebellum. Near amygadala, the hippocampus is responsible for declarative memory (facts; knowledge of). The procedural memory (skills; knowledge how) is from basal ganglia and cerebellum.

Title: "Neuroscience: philosophical and political implications"
Speaker:Dae-Shik Kim(Univ. of Boston and Collaborating Professor, Department of
Time/Date: 2:30-4:00 pm, April 9th (Friday)
Place: Room 217, CMS Building
It's going to be a rather "brainstorming" talk that discusses questions
1) Is Artificial Intelligence possible - and if so, should we do it?
2) Is there a free will? - legal implications
3) Can neuroscience help us to predict people's behavior?
4) Can neuroscience help us to manipulate people's opinion?
5) How logic and mathematics can help us to bypass brain's design flaws
I have been thinking about the above topics quite a bit recently (based
on many recent exciting neuroimaging and developmental neuroscience
data). It might be useful for the BioSystems students to think a little
bit about the possible consequence of their work, and also about what
their responsibilities are as rational thinking (hopefully!) scientists
and engineers in a society which is becoming more and more irrational
these days (in particular in the USA). This talk is meant mainly for
undergraduate/graduate students in the department, so it would be nice
to schedule it on a day/time that is free of other classes. For me, any
time between April/6 - April/9 will be fine.
