Ventral
the anterior intraparietal area (AIP) of macaque monkeys discharge in response to viewing and/or grasping of three-dimensional objects
representing object features relevant for grasping (Sakata, Taira et al. 1995; Sakata, Taira et al. 1998).
Area AIP has strong recurrent connections with the rostral part of the ventral premotor cortex (area F5) in the macaque (Matelli,
Luppino et al. 1994). The ventral premotor cortex is involved in grasp planning and execution (Rizzolatti, Gentilucci et al. 1990), and
projects to motoneurons that control finger muscles (Dum and Strick 1991). The activity of neurons in the primary motor cortex (area
F1) when contrasted to the premotor activity suggests that the primary motor cortex may be more involved in dynamic aspects of
movement, executing ‘instructions’ sent by the premotor cortex. Thus, it is generally accepted that the Anterior IntraParietal area –
Ventral Premotor Cortex – Primary Motor Cortex network (AIP-F5-F1 circuit in short) is responsible for grasp planning and execution
(Gallese, Murata et al. 1994; Jeannerod, Arbib et al. 1995; Fagg and Arbib 1998; Fogassi, Gallese et al. 2001).

24. About representation
According to George Lakoff(1990), thre are two different
kinds of representations;
a predictive category and a motivative category.
• The tap is running. :
• Estimates of the total cost run well over $10000 :
10000
• Sheʼs run for office four times but only won once.:
4 1
• The streets run like the grid of a go board. :
(the examples taken from Eijiro)
This tells you that the usage of “run” can be extended
because the behind category is not predictive but motivative.

37. We should stop mapping between
syntactic structures and meaning
brought from somewhere.
A system (data) itself must
create meaning by itself like our
brain systems do.
