static, dynamic and kinematic
components of a brain activity
• Memory is the static part; the flow of free
energy flow is the dynamic part; emotion and
reasoning are the kinematic part and attention
is a factor of continuity in kinematics.
• The inner, middle and frontal lobe are the
attraction sites for driving; where the cortex is
the bed-stream for the activities forward.
An activity pathway
• A pathway is the route for the sequent activities and receives a
number of inputs and memories linked with many variety of
memory pixels as the media; when the circuit of pixel memories are
attracted by needs and complete the functional aspect of the activity.
• Attention and focus preserve the continuity of the activity by the
connecting the memory pixels so that definite inputs and memories
as the static milestones would be linked. Uniqueness, splitting, or
sustainability of the attention depends on how complex is the
interaction of the need and the environment and memorized
circumstances (inputs and memories).
• Attention attractors can be unique or several depending on the
complexity of the stressful inputs and attractors sensitivities.
• The stronger the attractors; the more automatic and straight the
activity.
General functions of the brain
• Perception, cognition and action operation are
the main functions of the brain as the
kinematic part of the brain activities. Most of
the time, these processes are not distinguished,
but overlap each other; especially in more
complicated brain activities. Perception and
cognition are highly integrated and use the
same attractor or attentional resources.
Perception
• Perception as the pre-perception stage is the sensory
inputs receiving and screening processes. Screening
would apply for the separation of the parts previously
experienced and there is a saved memory for those
pieces of the input from the parts that are new
experiences and no previous saved memory exists for
those parts. The screening process, which during that,
the captured pictures are compared for available
memories of the pieces, consists of resonating for the
saved pieces and straining for the new entries. This part
is the shared portion between perception and cognition
processes.
Cognition
• Cognition functions are the mental processes
which conclude in products like remembering,
recognizing, understanding, problem solving
or decision making. Basically attention
effectiveness and memory recalling develop to
advanced functions of language production
and understanding, problem solving and
decision making.

Due to changes in simultaneous firing pattern by the synapses configuration changes,
cognition function is a function of the brain detail general structure in the level of neural
network arrangement and their slight changes by stress forces, when active.
alterations in brain structure and function are intimately tied to alterations in cognitive
function.
"Establishing such links between brain and cognition is the principal goal of cognitive
neuroscience" and kinematics is successful to provide a fair descriptive model for such a link.
Such a link according to kinematics, not only change by months and years, but fluctuating
slightly during a day.
the relationship between brain and cognition is a dynamic one and may change across the
lifespan,
The brain neural network changes depends on the type of functionality of different areas and
kinematically, some areas are more effective than others. Furthermore, it firmly depends on
the type and different daily experiences of the individual. Therefore, "age-related changes in
brain structure and function are not uniform across the whole brain or across individuals". The
brain tissues aging significantly changes the stress-strain behaviour, although it would be
different for different parts of the brain.

Pathway determination
• Attention and memory functions as well as
related processing speed in different locations
determine the pathway for a brain activity. The
attractors (including needs, desires and goals)
combining with the environment
circumstances and the action operatororientation ( emotions, reasoning), all together
have a determinative role in the neural route
continuation as the pathway.
Attractors in a brain activity
• A brain activity can remain as a confined temporary strains along a building
its working memory. It can become a short memory when the following
stress relaxation of the dreaming equalizes the layer; otherwise will be
erased (forgotten). However, a "working memory is really a divided
attention task“ for the next activities.
• Emotional (automatic) attractors are located in the amygdala, the attention
attractors are hosted in the prefrontal cortex. The "role for dorsolateral
prefrontal cortex (PFC) in the manipulation and updating of information in
working memory, with left PFC involved more in verbal tasks and right
PFC in visuospatial tasks". Reduction of attentional resources is either due
to increase of emotional drives and deficient perception and cognition
processes. However, the activities need less or no attention like automatic
tasks would remain unaffected too.
• Attractors for a pathway configuration and networks selection in a
pathway are needs, emotions and attention.

Memory in the brain; inputs entries in
to the brain

As static part of a mentation, memories like a real object in environment have
location and time orientations. An excitation that correlate the time and space to
remind a memory is the virtual circumstance that an emotion creates that. Similarly,
an excitation that correlate the time and space to create an image is the virtual
circumstance that a reasoning creates that.
Reminding a memory evokes an emotion or a reasoning connection; and an
emotion or a reasoning connection recalls a memory; when the attractors (needs)
and circumstance are the source of an emotion.
There are different types of memories with emotion or reasoning attachments
including: episodic memory (memory of the experienced events in a particular
place and time and are attached to a kind of emotion); semantic memory (the made
integrated knowledge or explanatory philosophy about the environment, which are
not attached to a place or a specific time); autobiographical memory (one's past
history of life including episodic and semantic memories); implicit memory
(memory of the same family memories which provide a collective pattern or a
trained procedure to follow in similar cases unconsciously); prospective memory
(memory of those are planned to do).
Memories site locations
• The specific memories as episodic memory are hypothesized that
located in hippocampus; while collective memories like the
semantic memory should be located somewhere in the frontal lobe.
The implicit memories are functional memories and are mapped
over brain outer layer.
• The results of the brain activities (like decisions or plans to do
works) are located similarly in some areas of the frontal lobe and
would store the result as a working memory.
• By such assigning memories to different structure all over the brain,
it can be theorized that the neural networks are the sites for different
types of memories and the memory individuality depends on how
the housing structural configuration is rigid or flexible. The more
rigid; the more static (like facts and events). The more flexible; the
more implicit or collective memories.
