How does a neural assembly constitute an intention?
Well, I guess the exact implementation and distribution
is different in each person. The details of encoding
(activation patterns, frequencies, etc) is probably
still controversial among neuroscientists. What
we know for sure is roughly which region corresponds
to which level of abstraction. A neural assembly
in the highest motoric region of abstraction represents
an intention or abstract goal.
As you know, the cortex is organized as follows
from top to bottom: the highest layer, the prefontal
cortex, contains intentions and plans movements, the
layer beneath organizes how these movement are
arranged into sequences, and the lowest layer determines
how these sequences produce concrete movements.
* prefontal cortex plans movements:
abstract intentions and plans
* premotor cortex organizes movement sequences:
abstract actions
* motor cortex produces specific movements:
concrete actions and particular movements
The organization for the sensory layers is similar
and ranges from concrete perceptions to abstract
beliefs: the lowest layer, the sensory cortex
(incl. somatasensory cortex, primary visual cortex
or V1, primary auditory cortex,.. ), makes concrete
perceptions of physical patterns. The layer above,
the secondary cortex (incl. somatosensory cortex,
secondary visual cortex (or V2), secondary auditory
cortex, ..) recognizes how these patterns are
arranged into abstract objects and forms. Finally
the highest layer (incld. tertiary somatosensory
cortex, tertiary visual cortex (or V3-V5), tertiary
auditory cortex, ..) forms abstract beliefs (color
form, static and dynamic form, words, motions,
stories).
* tertiary cortex perceives abstract static and
dynamic forms, words, motions: abstract beliefs
* secondary cortex perceives pattern forms:
abstract perceptions
* sensory cortex perceives physical patterns:
concrete perceptions

Do you have a good example of how a neural assembly constitutes an intention
in an organism we could paw over for a while?
